HRIR/Nimbus-2 Images of Nighttime Brightness Temperature on 70 mm Film V001 (HRIRN2IM) at GES DISC

Version 001 eng
  • Abstract
    HRIRN2IM is the Nimbus-2 High-Resolution Infrared Radiometer (HRIR) data product containing scanned negatives of photofacsimile 70mm film strips. The images contain orbital nighttime (3.5 to 4.1 microns) brightness temperature values showing cloud cover and the Earth's surface temperature. Each orbital swath picture is gridded with geographic coordinates and covers a distance approximately from the north pole to the south pole. The images are saved as JPEG 2000 digital files. About 7 days of images are archived into a TAR file. The processing techniques used to produce the data set and a full description of the data are contained in section 3.4.1 of the "Nimbus II Users' Guide. "The HRIR instrument was designed to perform two major functions: first to map the Earth's cloud cover at night to complement the television coverage during the daytime portion of the orbit, and second to measure the temperature of cloud tops and terrain features. This HRIR instrument was launched on the Nimbus-2 satellite and was operational from May 15, 1966 through November 15, 1966. This product was previously available from the NSSDC with the identifier ESAD-00226 (old ID 66-040A-03B).
  • Purpose
    These images can be used to supplement the level-1 radiance data files from the HRIRN2L1 data product.
