1. New IAGA Web Pages
From: Dan Baker <Daniel.Baker@lasp.colorado.edu>

The International Association of Geomagnetism and Aeronomy (IAGA) has new web pages at: www.iugg.org/IAGA.

The web site provides information about the upcoming IUGG meeting in Sapporo, including the IAGA Scientific Program. Please check it out.


2. ACE-Wind-IMP8-Earth "Impact Parameters" available at NSSDC
From: "Joseph H. King" <king@mail630.gsfc.nasa.gov>

A new data product is ftp- and FTPBrowser-accessible from NSSDC that gives "impact parameters" for any pair of the four bodies: ACE, Wind, IMP 8 and Earth. This is the distance by which the second body would miss seeing a plasma element observed by the first body, assuming the element was flowing radially away from the sun at 390 km/s and allowing for the 30 km/s circumsolar motion of the second body (with all other bodies) after the first body's observation of the plasma element.

This "impact parameter" is being used at NSSDC in its OMNI-2 preparation efforts by constraining the time spans used in regressions of data from one spacecraft against those of another spacecraft. But they obviously have relevance to analyses assessing local solar wind fluctuation scales, LWS-relevant geophysical predictability from L1 observations, etc.

Annual files of hourly resolution impact parameters, and a 1995-2002 file of daily resolution impact parameters are ftp-accessible from ftp://nssdcftp.gsfc.nasa.gov/miscellaneous/orbits/impact_parameters/
Graphical browse and subsetting of the daily resolution data are provided by the FTPBrowser interface at http://nssdc.gsfc.nasa.gov/ftphelper/impact.html

1. Polar, Wind and Geotail Mission Data
From: Barbara L. Giles (barbara.giles@gsfc.nasa.gov)

Starting Friday, September 27 the full Polar, Wind and Geotail science dataset will be available on-line from a new mission data server rather than the ISTP Central Data Handling Facility (ISTP/CDHF).

All level zero data products for the entire mission lifetime along with the related ancillary products and operational products are available via anonymous ftp at:ftp://pwgdata.gsfc.nasa.gov/pub/

There is a README file at that site giving additional information and contact information:

All key parameter data products for the entire mission lifetime along with orbit/attitude data products continue to be supplied via the web or by anonymous ftp at: http://cdaweb.gsfc.nasa.gov/

Specialized processed data products continue to be served by the individual instrument teams. Addresses for that data are available at ftp://pwgdata.gsfc.nasa.gov/pub/00readme.html.

All data services from the ISTP/CDHF will be discontinued on September 27. All data previously served by the CDHF, regardless of the mission, continue to be available either through the NSSDC, the NSSDC CDAWeb or through individual mission ftp and web sites. Please contact the NSSDC or the mission project scientists for further information regarding services for a particular spacecraft.

2. STEP Handbook of Ionospheric Models
From: Shawna Johnson <shawna@gaim.cass.usu.edu>

Due to the large number of requests, the STEP Handbook of Ionospheric Models, dated August, 1996 and edited by R. W. Schunk, has been reprinted. If you would like to receive a copy, please contact: Shawna Johnson, Center for Atmospheric and Space Sciences, Utah State University, 4405 Old Main Hill, Logan, UT 84322-4405; Telephone: 435-797-2962; Fax: 435-797-2992; shawna@cc.usu.edu.

1. IMP 8 Bow Shock Database Accessible via FTPBrowser at NSSDC
From: "Joseph H. King" <king@mail630.gsfc.nasa.gov>

A dataset of IMP 8 bow shock crossings for the 1994-2000 ISTP era is newly available at http://nssdc.gsfc.nasa.gov/ftphelper/bowshock1.html. There is one record for each of ~3,000 shock crossings, or ~15 crossings per IMP orbit on average. Each record contains the time and location of the crossing, observed upstream field and plasma parameters, observed downstream density, several derived parameters (various Mach numbers, etc.) and a set of flags related to the reliability of the shock identifications and characterizations.

The interface mentioned above allows the selection of records by time and/or by numeric ranges of any of the parameters in the records. The data are also accessible as annual ASCII files from ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/imp/imp8/bowshock_crossings/

The basic shock identification work and specification of upstream observables was done by members of the IMP magnetometer team at Goddard (A. Szabo, J. Merka, T. Narock) and of the MIT plasma team (K. Paularena, J. Richardson, L. Finck). Each team looked at both field and plasma data and reconciled their identifications jointly. The derived parameters were computed, and the FTPBrowser interface created, at NSSDC by N. Papitashvili.

In the coming months, additional shock-crossing records will be added to the dataset for the preceding 20+ years of the IMP 8 mission.

This work was supported by a grant from NASA's Applied Information System Research Program.

3. The 2002 Sun-Earth Connection (SEC) Roadmap Available
From: Stephen A. Fuselier (Chair, SEC Roadmap team)

The Sun-Earth Connection (SEC) Roadmap team has completed the 2002 SEC Roadmap. The final draft of the Roadmap is available online at the SEC Roadmap Web site "http://sec.gsfc.nasa.gov/sec_roadmap.htm". On the website, there is an option to download the version with or without the mission descriptions (10 MB versus about 1 MB). Also provided on this website is the opportunity to submit comments on the report. Over the next two months, members of the community will be preparing for a November meeting where the roadmaps from the Office of Space Sciences directorates will be incorporated into the OSS Strategic Plan for 2003. The SEC Roadmap is an important part of our directorate's input into this Strategic Plan.

Prominent progress in science is inevitably associated with controversies. Thus, young researchers in particular, have to learn how to persevere during the period of controversy and struggle for acceptance. Unfortunately, the skills needed are not taught in textbooks or monographs, which mostly describe the consensus of contemporary experts. This book, which is based on my own experiences as a scientist, describes the history of the progress made in auroral science and magnetospheric physics by providing examples of ideas, controversies, struggles, acceptance, and success in some instances. Although no general methodology (if any) is mentioned, I hope that the reader will learn about the history of progress in auroral science and examples (right or wrong) of dealing with the controversies.

1. The American Society of Information Science Named Syun-Ichi Akasofu
as a Top Cited Author
From: Editor <editor@igpp.ucla.edu>

The American Society of Information Science (IS) recently named Syun-Ichi Akasofu of the University of Alaska Fairbanks (sakasofu@iarc.uaf.edu) as one of "the world's most cited authors". This list of highly cited researchers is based on publications that feature important scientific developments of the last two decades. Less than one half of a percent of all published researchers earn the distinction.

Congratulations, Syun!

1. Revised NASA Marshall Engineering Thermosphere Model Available
From: "Bill Vaughan" <vaughan@nsstc.uah.edu>

The NASA Marshall Engineering Thermosphere Model--Version 2.0 has been published as NASA/TM-2002-211786 dated June 2002. The model is based on the extensive work of Luigi Jacchia and his colleagues at the Smithsonian Astrophysical Observatory during the 1960's and 1970's. The current version of the model has evolved, based on work conducted at the NASA Marshall Space Flight Center, over a long period of time. The report describes the development history leading to this second version of the model, attributes of the atmosphere at orbital altitudes, and the methods used to model those attributes. Copies of the report and computer code for the model are available on request to Jerry K. Owens, Email: jerry.owens@msfc.nasa.gov.
