SCR/Nimbus-4 Level 1 Radiance Data from CD-ROM V001 (SCRN4L1RAD_CDROM) at GES DISC

SCRN4L1RAD_CDROM is the gridded Nimbus-4 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. The CD-ROM contains corrected radiances in a daily 4 degree latitude x 10 degree longitude grid format, as well as the original orbit format. The data for this product are available from 27 July 1970 to 2 November 1972. 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 single CD-ROM in ASCII files of hexadecimal characters, and are available in a single gzipped Unix tar archive file. 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.
