    • SCR/Nimbus-5 Level 1 Calibrated Radiances V001 (SCRN5L1RAD) at GES DISC

    Metadata Updated: April 10, 2025

    SCRN5L1RAD is the Nimbus-5 Selective Chopper Radiometer (SCR) Level 1 Calibrated Radiances data product. The calibrated radiances are measured at 16 channels from 2.3 to 133 micrometers with a ground resolution of 25 km, and are "declouded" (interpolated and smoothed across regions of cloud). The radiances were used to obtain the global temperature structure of the atmosphere up to 50 km altitude, the distribution of water vapor, and the density of ice particles in cirrus clouds. The data were recovered from the original 9-track tapes, and are now stored online as daily files in their original proprietary binary format with about 14 orbits per day.

    Spatial coverage is near global from latitude -80 to +80 degrees. The data are available from 13 December 1972 (day of year 347) to 26 December 1974 (day of year 360). The principal investigator for the SCR experiment was Dr. John T. Houghton from Oxford University.

    This product was previously available from the NSSDC with the identifier ESAD-00250 (old ID 72-097A-02A).
