SCR/Nimbus-5 Level 1 Radiance Data from CD-ROM V001 (SCRN5L1RAD_CDROM) at GES DISC

SCRN5L1RAD_CDROM is the gridded Nimbus-5 Selective Chopper Radiometer (SCR) Level 1 Radiance Data Product. The radiances are measured by 16 channels at 2.3 to 15 micrometers with a ground resolution of 25 km. This product contains corrected and uncorrected radiances in a daily 4 degree latitude x 10 degree longitude grid format, as well as the original orbit format and reformatted copies of the original tapes. This was the follow-on to the SCR experiment flown on Nimbus-4. The data for this product are available from 13 December 1972 to 20 April 1978. The principal investigator for the SCR experiment was Dr. John T. Houghton from Oxford University.

This product was created by the Oxford University's Atmospheric, Oceanic and Planetary Physics (AOPP) group. The data are stored on a set of 28 CD-ROMs in ASCII files of hexadecimal characters, and are available in gzipped Unix tar archive files. The first CD-ROM contains the gridded radiance data and a few original tape data files, the subsequent CD-ROMs contain the remaining compressed copies of the original data tapes. The byte-ordering in the data files follows the DEC convention for 16-bit integers of less significant byte first. Normal 2's complement integer storage is assumed.
