SSDOO Attends IAGA Meeting

Volume 13, Number 3, September 1997
By Dieter Bilitza, Ramona Kessel, and Natalia Papitashvili

Dieter Bilitza, Ramona Kessel, and Natalia Papitashvili recently attended the 8th Scientific Assembly of the International Association of Geomagnetism and Aeronomy (IAGA) in Uppsala, Sweden (August 4-15, 1997). It was an excellent opportunity for continuing or beginning discussions and collaborations with international colleagues. There was a strong European presence at the meeting.

Dieter Bilitza gave a talk during the IAGA space weather session on "Ionospheric Predictions Using IRI and GPS Data," discussing the use of the Global Positioning Satellite (GPS) electron content measurements for near real-time updating of the International Reference Ionosphere (IRI) electron density model. He also gave an invited topical review in the Solar-Terrestrial Energy Program Working Group (STEP WG) 6 (Informatics) Session on "Science Tools on the Internet-Access to Data and Models." The STEP sessions were part of the 9th Solar-Terrestrial Physics (STP) Symposium organized by the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP), held jointly with the IAGA meeting. The IRI talk triggered several questions and follow-on discussions regarding the most recent IRI and the spatial resolution of the GPS data maps.

Ramona Kessel gave a presentation entitled "Motion of the Earth's Bow Shock Using ISTP Multispacecraft Observations." Before and after her presentation she had extensive discussions with various colleagues concerning this research because of the significant differences seen in the observations between the dawn and dusk sides of the bow shock. A manuscript is in preparation. She also participated in various Cluster and Common Data Format (CDF) discussions.

Natalia Papitashvili presented two contributed papers and co-authored one poster presentation: "Network-Oriented Services at NASA's National Space Science Data Center," "Space Weather Assets at NASA's National Space Science Data Center," and "Global Changes in the IMF and Solar Wind Interaction with the Earth's Magnetic Field During Three Solar Activity Cycles." After her presentations she received positive feedback from a number of people regarding the "space weather-related" assets at NSSDC and suggestions for improving NSSDC services.

Natalia Papitashvili and Dieter Bilitza also attended an ad hoc open meeting on space weather during the IAGA meeting. Some people expressed their interest in internationalization of space weather-related programs. There were 12 to 15 presentations made by representatives of a number of countries where some efforts on the space weather studies are underway. NSSDC expects to continue to play a role in space weather. A move that IAGA must have a working group on space weather was not unanimously supported. This was forwarded to the IAGA Division III business meeting, where an ad hoc preliminary working group was formed under the chairmanship of Daniel Baker of the University of Colorado.

Presentations at the meeting frequently used data available from the NSSDC/SPDF Web-based systems, particularly CDAWeb and SSCWeb, and from NSSDC's FTP sites. Participation at the conference and in the discussions that followed allowed an opportunity to improve approaches in serving the national and international scientific communities.
