Hourly Averaged Alpha Particle (11-90 MeV/Nuc) Data
NSSDC ID: SPHE-00214
Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)
Time span: 1975-08-01 to 1992-04-30
Description
This data set was originally written by an IBM 360 computer in EBCDIC and restored on an IBM 9021 computer in ASCII. The tape contains 1 month of data per file. Each record in a file is 60 bytes long. It lists, in sequence, year (last two digits), day number, hour, and spacecraft number (7 or 8 of the IMP series), followed by the hourly averaged flux (1/sq cm-s-sr-Mev) of alpha particles in one of three energy bands. A1 in the sequence denotes the 25-90 MeV band, A2 denotes the 20-25 MeV band, and A3 denotes the 11-20 MeV band. Plots of the data have appeared in the several issues of Solar Geophysical Data-Comprehensive Report, published by NOAA, Boulder, Colorado.
