    • THIR/Nimbus-6 Images of Daytime and Nighttime Brightness Temperature on 70 mm Film V001 (THIRN6IM) at GES DISC

    Metadata Updated: December 6, 2023

    The THIRN6IM data product consists of daily montages of brightness temperatures on 70 mm photofacsimile film strips from the Nimbus-6 Temperature-Humidity Infrared Radiometer measured at 6.7 and 11.5 microns. Daytime and nighttime orbital swaths are displayed in strips, each corresponding to a distance approximately from pole to pole and a width from horizon to horizon. The ground resolution of 22.6 km for 6.7 microns and 8.2 km for 11.5 microns at nadir decreases as the horizontal distance from the subsatellite track increases. Each film strip is gridded with geographic coordinates and is identified by orbit number, time, and an indication of whether it is daytime (D) or nighttime (N). The images are saved as JPEG 2000 digital files. About 1 week of images are archived into a TAR file. Additional information can be found in section 2.4.1 of "The Nimbus 6 User's Guide."

    The Nimbus 6 Temperature-Humidity Infrared Radiometer (THIR) was designed to detect emitted thermal radiation in both the 10.5- to 12.5-micron region (IR window) and the 6.5- to 7.0-micron region (water vapor). The window channel measured cloudtop temperatures day and night. The other channel operated primarily at night to map the water vapor distribution in the upper troposphere and stratosphere. The THIR experiment made measurements from June 18, 1975 until May 6, 1976.
