2. Global Birkeland Currents Key Parameter Data and Quick-look Products
Available On-line: http://sd-www.jhuapl.edu/Iridium/
From: Brian J. Anderson <brian.anderson@jhuapl.edu>

We are pleased to announce that key parameter data and quick-look
products derived from magnetometer data of the Iridium Satellite
constellation are now available on line at
http://sd-www.jhuapl.edu/Iridium/ .
The page provides open community access to view and retrieve data products
from the Point-Mosaic Auroral Imaging project conducted under sponsorship
by the National Science Foundation. These data products were developed at
JHU/APL and are publicly released with the approval of Iridium Satellite
LLC. The available data cover 18 February 1999 through 31 May 2003 and
will be updated as data are received and processed, approximately weekly.
Data coverage is nearly 100% although there are some days for which data
are not available.

Products released on this page include (but are not limited to):
(a) Daily summary plots of the intensity, distribution and latitude
distribution of magnetic perturbations associated with Birkeland currents:
polar plots at six hour accumulations and time series plots with 15 minute
time steps;
(b) Monthly summary plots showing the time histories of the net magnetic
perturbation due to the Birkeland currents and their lowest latitude
(c) Data at 15 minute time steps of field aligned current analogues of the
auroral indices, (AU, AL, and AE) for both hemispheres and separated by
magnetic daytime and nighttime hours;
(d) Data for estimates of the mean, minimum and maximum latitudes of the
large scale Birkeland currents also at 15 minute time steps;
Descriptions of these and other data products, processing steps and file
formats are provided on the page.

These data are relevant for study and retrospective specification of the
large scale auroral field aligned currents. The key parameter data are to
be used for non-commercial purposes only specifically including education
and scientific research. They are appropriate for survey, event
identification, and preliminary science investigations. Because there are
some noise artifacts in the data products, investigators are advised to
contact Dr. B. J. Anderson prior to conducting detailed science
investigations. Analysis for field aligned current distributions can be
conducted on a case by case basis in collaboration with JHU/APL but because
quantitative measures of the error and reliability of the results are still
under development, these products are not yet produced for public access.
Acknowledgment and notification of JHU/APL and Dr. B. J. Anderson are
required if information in or derived from these products is used in
publicly presented or published materials.

1. New Solar Wind Data Products Available on the Genesis Mission Website
From: Roger Wiens <rwiens@lanl.gov>

"Additional solar wind data products are now available on the Genesis
Mission website (http://genesis.lanl.gov). Recent additions include
processed level-2 data for the first year of the mission, browse ion data
based on on-board calculated ion moments through mid-April 2003, and
magnetic field orientation data through the end of 2002. The level-2 data
include proton density, temperature, velocity vector, alpha/proton ratio,
and the times of bi-directional electron streaming at 2.5 minute intervals.
The browse data include the same parameters except the velocity is 1-D, and
include running 1-hour averages, as well as several additional parameters
related to real-time identification of coronal mass ejections. The
magnetic field orientation data are based on the peak flux direction of the
suprathermal electrons and are generally accurate to better than 5 degrees,
but contain a sign ambiguity. The website also includes solar-wind browse
data plots and electron spin angle plots. Browse data plots are generally
posted within 1-3 days of data acquisition, allowing views of very recent
solar-wind activity. We will be adding more level-2 data shortly.

Genesis was launched August 8, 2001 and has been in an L1 halo orbit since
November '01. Genesis is a solar-wind sample return mission. Solar-wind
collection is to continue until April, 2004, at which time the spacecraft
will leave L1 for its Earth return phase. The samples will be returned via
a re-entry capsule, which separates from the main portion of the spacecraft
and will re-enter the Earth's atmosphere September 8, 2004.

We are currently proposing to re-direct the spacecraft, which is free to
fly without the return capsule, and which will have a very large reserve
of propellant. The proposed new mission would take the Genesis spacecraft
to a distant retrograde orbit which would allow it to participate in
multi-spacecraft observations at distances between 5 and 10 million
kilometers from Earth, well beyond the L1 and L2 points. More information
is available on the Genesis data website."

2. Ulysses Open Data Policy
From: Richard Marsden <Richard.Marsden@esa.int>

The scientific data from the Ulysses mission is now being made available
to the general scientific community with the minimum possible delay. It
is hoped that this new data policy will encourage and facilitate
multi-mission and other collaborative research into global physical
phenomena in the heliosphere. Ulysses, with its unique orbit inclined at
80.2 degrees to the Sun's equator, provides an ideal complement to present
(and future) missions investigating the heliosphere, and the Sun's
influence on geospace.

The data provided by the Ulysses investigations include the following:

VHM/FGM - high resolution interplanetary magnetic field measurements in
spacecraft and RTN coordinates
SWOOPS - full time resolution solar wind plasma parameters
SWICS - full time resolution solar wind ion kinetic parameters and
abundance ratios of selected charge states
URAP - high resolution radio and plasma wave peak/average intensities and
comprehensive summary plots
HISCALE, EPAC and COSPIN - high resolution ion and electron intensities
(including PHA) over a wide range of energies
GAS - full sky maps of interstellar helium and celestial UV intensities
GRB - full resolution solar X-ray and gamma-ray burst count rates
DUST - cosmic dust impact event parameters
SCE - coronal sounding measurements using radio science

Data coverage extends from launch (in October 1990) well into 2003 for
most instruments, representing more than a complete solar cycle of
continuous measurements.

Data may be obtained from the ESA Ulysses website
(http://helio.esa.int/ulysses/) or from the Ulysses web pages at NSSDC
(http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1990-090B). CDROM
collections of measurements are also available for selected data sets (the
Jupiter encounter, Solar Minimum Mission ESA-SP, SWICS data archive and
HISCALE full resolution data). Documentation describing in detail the
instruments and the data sets is also provided, as well as contact points
within the experiment Principal Investigator teams. Summary plots of
selected parameters at varying time resolutions are included for quick
browsing of periods of interest.

3. LWS/CDAW Data Open to the Scientific Community
From: Nat Gopalswamy <gopals@fugee.gsfc.nasa.gov>

A Coordinated Data Analysis Workshop (CDAW) was conducted last Summer
(July 22-26, 2002) to study the Large Solar Energetic Particle (SEP)
Events of solar cycle 23 (until the end of 2001). The CDAW brought
together scientists of Living With a Star (LWS) disciplines to interact
and establish long-term collaborations. Data, data products, models, and
analysis tools were assembled for the CDAW. The data from the CDAW and
the results produced during the CDAW are now available on line to the
broader scientific and space weather community for continued research.
Data from 40 different sources were assembled for the CDAW covering the
entire Sun-Earth Space: solar sources of SEP-producing CMEs to the impact
of SEPs on the ozone layer. Movies, images, plots and digital data for
each one of the 48 SEP events can be downloaded from


First-cut results from the LWS/CDAW will be soon published in a special
section of the Geophysical Research Letters. Interested researchers are
encouraged to do further analysis of the data. If you use the data from the
data base for publication, we request you to acknowledge the data base. If
you have any questions, please feel free to contact Nat Gopalswamy

4. A New Release of the GEOPACK Software Available Online
From: Nikolai Tsyganenko <Nikolai.Tsyganenko@gsfc.nasa.gov> and
Paul O'Brien <Paul.OBrien@aero.org>

A new FORTRAN-90 version of the software package GEOPACK-2003 has been
developed (NT) and translated into MATLAB (PO). The GEOPACK library includes
19 FORTRAN subroutines for magnetospheric modeling studies, in particular,
the internal (IGRF/DGRF) field model for the period between 1965 and 2005,
a group of routines for transformations between various coordinate systems,
a field line tracer, and two magnetopause model codes.

The original FORTRAN package was incepted in 1979, and its latest version
emerged as a result of several upgrades, based on numerous helpful comments
of many users received since its first release. An across-the-board revision
of the previous edition was made, with the goal to make the package simpler
and more compiler-independent. The package is provided with a detailed
documentation file and two sample main programs.

The FORTRAN package is available from:


and the MATLAB version can be downloaded from


5. Multi-Spacecraft Bowshock Database at NSSDC
From: Natalia Papitashvili <natasha@mail630.gsfc.nasa.gov> NSSDC/QSS

NSSDC's bowshock crossings database at
http://nssdc.gsfc.nasa.gov/ftphelper/bowshock.html has been
significantly improved recently by adding data from a number of
spacecraft and enhancing its Web-based interactive interface. The
database now includes the bowshock crossings made by the following
spacecraft: IMP-8 (1992-2000), Geotail (1995-1997), Magion (1996-1997),
and Cluster (2001-2002). Time coverage for each, except Magion, will
be further extended.

Each record in the database contains the time and location of the
actual crossing, the observed upstream IMF and solar wind plasma
parameters and the downstream plasma density (IMP only), as well as
several NSSDC-computed parameters (flow pressure, sonic and Alfvenic
Mach numbers, beta, etc.). The record's format is the same for all
spacecraft, although some fields have meaningful values only for IMP.

The new Web-based interactive interface identified above allows users
to select any combination of spacecraft, time span, and/or ranges for
any parameters in the database. We have also added output sorting
capabilities by date and time or by any user-selected parameter.
The underlying data are accessible as annual ASCII files from

These data and interfaces allow the user to accomplish several
scientific tasks, for example, (1) find nearly simultaneous crossings;
(2) specify the crossings for specific IMF and solar wind conditions;
(3) find the crossings in the certain regions of the bowshock (e.g.,
dayside, flanks, etc).

The IMP-8 basic shock identification and specification of the upstream
observables were done by the members of the IMP-8 magnetometer group at
Goddard (A. Szabo, J. Merka, T. Narock) and of the MIT's IMP-8 plasma
group (K. Paularena, J. Richardson, L. Finck). The Magion-4 (Interball-
Tail's sub-satellite) bowshock crossings were supplied by J. Safrankova
and Z. Nemecek (Charles University, Prague, Czech Rep.) The Geotail and
Cluster crossing were identified by R. Kessel (GSFC). The NSSDC team is
N. Papitashvili, R. Kessel and J. King.

1. DMSP Thermal Plasma Data Now On-Line
From: Marc Hairston <hairston@utdallas.edu>

The Center for Space Sciences at the University of Texas at Dallas
announces that after years of distributing the DMSP SSIES (thermal plasma)
in bits and pieces, we now have the on-line capability to distribute these
data. These data files include the three dimensional velocity vector of
thermal plasma (ram drift and the two cross track drifts), ion and
electron temperature (Ti and Te), ion density (Ni), and fractional
composition of ions (H+, He+ and O+) all at with a four-second resolution.
Further, there are quality flags (good/high confidence, caution,
poor/don't use, or undetermined) for each four seconds of data in the
files to provide guidance for researchers wishing to use these data. So far
we have data for the years 2000 through 2002 completed and on-line. We
also have some portions of earlier data on-line as well and we list those
periods on the website. We are continuing to add new data after 1 January
2003 as it arrives and are working to fill in the historical record back to
1987 as time and further funding allow. Please visit the website at


to examine the data. If you have any questions about this, please contact
Dr. Marc Hairston <hairston@utdallas.edu>.

2. COSPAR/URSI International Reference Ionosphere - Software and Web
Interface Updated
From: Dieter Bilitza <bilitza@pop600.gsfc.nasa.gov>

The International Reference Ionosphere (IRI) is a data-based model
developed by a joint working group of the Committee on Space Research
(COSPAR) and the International Union of Radio Science (URSI). The
software and web interface for this model are available online and
were recently updated. The software files are available from the
National Space Science Data Center archive at
The most recent updated introduces a number of program technical
improvements for greater compatibility with different Fortran
compilers and now fully implements the new options for the topside
electron temperature and for the D-region electron density. In
addition the solar and magnetic indices files were updated with the
most recent values. IRI model updates are reported regularly and in
greater detail via an email distribution list (to sign up go to

The IRIWeb interface at
http://nssdc.gsfc.nasa.gov/space/models/iri.html lets user compute,
list, plot and download IRI parameters for a variety of input and
output options. IRIWeb has now been upgraded to provide access to the
latest version of the IRI model. In addition to the traditional IRI
parameters (Ne, Te, Ti, Ni, TEC) users can now also compute the
equatorial vertical ion drift, the ratio foF2_storm/foF2_quiet, and
the F1-layer occurrence probability. Several new input options are
provided: (i) the user can specify the sunspot number (R) and the
ionospheric index (IG), (ii) the STORM model can be turned on and
off, (iii) for the topside electron temperature the new
Triskova-Truhlik-Smilauer model can be used, (iv) for the D-region
electron density the new Friedrich-Torkar model can be used, (v) for
the F1 occurrence probability the user can choose between three model

1. Wind/SWE Plasma Ion Data Available at NSSDC
From: Natalia Papitashvili <natasha@mail630.gsfc.nasa.gov>

This note announces the availability at NSSDC of 1995-2001 solar wind plasma parameter data from the Solar Wind Experiment (SWE) on the Wind spacecraft. The data are at full resolution (92 sec) and contain proton and alpha particle parameters, plus uncertainties, as determined from nonlinear convecting bi-Maxwellian fits. Both species have densities, flow vectors and scalar thermal speeds; thermal anisotropies are included for protons. In addition, proton densities, flow velocities, scalar thermal speeds and thermal anisotropies as determined by taking moments over the distribution functions are also included. Finally, magnetic field vectors as determined by the Wind magnetometer (and averaged from 3-s to 92-s by the MIT team) and spacecraft location data are included in the data records.

The data are available with graphical browse capability from http://nssdc.gsfc.nasa.gov/ftphelper/wind_swe_2m.html

This FTPBrowser interface also lets users create screen lists or downloadable ASCII files for any time span and/or subset of data words in the basic records.

The data are also available via ftp as monthly ASCII files at ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/wind/plasma_swe/2-min/ The data will shortly be accessible from CDAWeb.

The SWE Principal Investigator is K.W. Ogilvie at GSFC. The Co-Investigator with main responsibility for the SWE ion observations is A.J. Lazarus at MIT. The ion data were prepared by Justin Kasper at MIT. Extensive documentation excerpted from Dr. Kasper's recent Ph.D. dissertation is also available at the above-cited ftp site in PDF format.

Feedback on prior versions of these data was provided by NSSDC and used by MIT during its data preparation effort. The feedback was based on FTPBrowser-enabled data review, including comparison of the fits-based and moments-based parameter values and, at hourly resolution, of these data with concurrent ACE and IMP data. (Joe King, now retired from NASA and NSSDC, remains active in OMNI-2 preparation including work with input data such as the 92-s SWE ion data.)

4. NOAA Solar X-ray Imager (SXI) Images Available in Near Real-Time --------------------------------------------------------------------
From: Steven Hill <Steven.Hill@noaa.gov>

NOAA's Space Environment Center (SEC) is pleased to announce that NOAA's SXI has been returning soft X-ray images of the Sun since January 22 (Press Release - http://www.noaanews.noaa.gov/stories/s1087.htm). The images are available in near real-time at http://sxi.ngdc.noaa.gov/. SXI is in a routine patrol mode most of the time, taking one full-disk, solar image per minute. SXI's imaging cadence, multiple spectral bandpasses, and near real-time data availability are unprecedented for an instrument imaging the Sun's multi-million degree corona.

SXI was launched on 23 July 2001 on NOAA's GOES 12 spacecraft. After undergoing a four-month checkout, the spacecraft was placed into on-orbit storage. SXI officially becomes operational on April 22 when GOES 12 reaches its final operating orbit. Until then, expect that test imaging sequences will interrupt the routine patrol imagery occasionally. We encourage you to look at the images and to use them in your work, but please see below.

Currently SXI performance looks nearly identical to that during its test phase in the fall of 2001. Pointing control is excellent. However, there appears to be a spatially localized, off-band light leak evident only in the images with the filter wheel in the 'OPEN' position. This light-leak was absent during the SXI test phase. SEC is currently analyzing the off-band source and working on a corrective software algorithm. When a correction algorithm is available, we will apply it to the images in real-time. Until the correction is applied, the 'OPEN' filter images are available with the caveat that this contamination exists. It is most evident in the southeast quadrant of the detector.

SXI images in FITS or browse format are available immediately (generally less than 5 minutes latency) from NOAA's National geophysical Data Center (NGDC) web site http://sxi.ngdc.noaa.gov/. This site also hosts movies in MPEG format, updated every five minutes. Further information on the SXI and updates to its schedule can be found at http://www.sec.noaa.gov/sxi/.

2. Cluster EDI Prime Parameter Data Available
From: Goetz Paschmann <gep@mpe.mpg.de> and Jack Quinn <jack.quinn@unh.edu>

The Cluster EDI team has made available its full Prime Parameter data set for 2001. The PP data consist of drift velocities, and the associated -VxB electric field, produced with data from 1-spin (4 sec) intervals. The PP data may be downloaded as zipped files for either 1-day or 1-month periods. The data are publicly available at the same web site as the team's 3-hour survey plots, which were made available in December. Please read the caveats and contact the EDI team with any questions. The web address is: http://edi.sr.unh.edu

4. Cluster-CIS Public Summary Data Available
From: Iannis Dandouras <Iannis.Dandouras@cesr.fr>

The CIS (Cluster Ion Spectrometry) team has made available 6-hour energy-time spectrograms on the experiment public web site. The data come from the CODIF (CIS-1) ion mass spectrometer and the HIA (CIS-2) ion sensor, they now cover the first year of operations (2001), and they will be regularly enriched with more recent data. The purpose of these spectrograms is to facilitate scientific collaborations within the space physics community, and to provide a quick way for identifying interesting events and checking the character of the CIS data.

These spectrograms have been processed with the most recent calibration values, however the users need to be cautious, and should consult the Caveats for the CIS data, available on the same web site. These spectrograms are not for publication, and the users should contact the PIs (Henri Rème and Iannis Dandouras).

The CIS web site URL is http://cis.cesr.fr:8000/CIS_sw_home-en.htm (link "CIS Spectrograms").

1. New Space Weather Maps Available on the Web
From: Y. Kamide <kamide@stelab.nagoya-u.ac.jp>

We are pleased to announce that space weather maps in terms of northern hemisphere electric potential and currents in the ionosphere, and other related parameters, are now available to the scientific community on a near real-time and forecast basis at the following URL:


with a U.S. mirror site at:


For these maps of ionospheric parameters to be constructed, ground magnetometer data from a number of observatories, solar wind data from the ACE spacecraft, as well as Weimer's empirical models of electric potential, are utilized along with the KRM and rt-AMIE inversion algorithms.
