The data on the CD-ROM will be in ASCII format, and MS-DOS access and plotting software will be made available from NSSDC's anonymous ftp site. The data cover the time periods, December 16, 1973 to December 11, 1978, for AE-C; October 6, 1975 to January 29, 1976, for AE-D; and December 1, 1975 to June-6, 1981, for AE-E. The UA merged mission file includes data from the following experiments: Cylindrical Electrostatic Probe (CEP); Atmospheric Density Accelerometer (MESA); Photoelectron Spectrometer (PES); Retarding Potential Analyzer/Drift Meter (RPA), Open; Source Neutral Mass Spectrometer (OSS), Closed; Source Neutral Mass Spectrometer; Neutral Atmosphere Temperature Experiment (NATE); Magnetic Ion-Mass Spectrometer (MIMS); Bennett Ion-Mass Spectrometer (BIMS); Low-Energy Electron (LEE); Ultraviolet Nitric-Oxide (UVNO); Visible Airglow Photometer (VAE); and Neutral Atmosphere Composition Experiment (NACE). In addition to the actual data, the CD will include brief descriptions of the satellite missions of each experiment, and the data format.
The CD-ROM will also include EUV reference spectra and photon flux data from the Solar EUV Spectrophotometer (EUVS). EUVS data were not part of the original UA submission, but were included on the CD because of their importance in specifying the solar energy input. Additionally, the CD will contain the software and documentation for models that are related to the AE data (International Reference Ionosphere, IRI, and MASS Spectrometer Incoherent Scatter [MSIS] thermospheric model). Independently, the access and plotting software will provide an option to directly compare the satellite densities and temperatures with their IRI and MSIS counterparts.
The CD is being created by N. Papitashvili with help from D. Bilitza, J. King and the GSFC/Code 914 scientists, A. Hedin, W. Hoegy, D. Pesnell, and J. Grebowsky.
