This data set consists of ISIS 2 Pulse Code Modulation (PCM) data that have been obtained through an AISRP-funded data restoration project. The PCM data contain header, time, AGC, frequency-marker information and telemetry-level data from all ISIS-2 instruments. Detailed information about the data restoration project can be found at http://nssdc.gsfc.nasa.gov/space/isis/isis-status.html .
Other archived data sets from the restoration project include: (1) the digitized full resolution ionograms in the PI-provided OS2 binary format (71-024A-01J); (2) the average-resolution ionograms (averages of each 4 successive 40 kHz 8-bit values) in OSII binary (-01L); (3) the average ionograms in CDF format (-01K); and (4) ASCII header files with pass-specific information (-01N).
ISIS-2 data are available to the extent permitted by telemetry station scheduling and the location of telemetry stations. The data selected for the ISIS data restoration effort include data from 24 telemetry stations. A list of stations can be found at http://nssdc.gsfc.nasa.gov/space/isis/isis-table1-new.html and their location on a worldmap is shown in http://nssdc.gsfc.nasa.gov/space/isis/isis_station_lar.GIF .
