Nimbus High Resolution Infrared Radiometer Grayscale Swath Data L1, TIFF, Version 1

This data set consists of daily, global grayscale TIFF images derived from radiative temperatures measured in the 3.4 to 4.2 µm window. These data were detected by the High Resolution Infrared Radiometer (HRIR) on board the Nimbus 1, Nimbus 2, and Nimbus 3 satellites during 1964, 1966, and 1969-1970. The Nimbus HRIR sensor was used to map the earth's nighttime cloud cover and to measure cloud top temperatures or surface temperatures. Note: This data set is not georeferenced and contains some gaps in temporal coverage because of missing data.

This is the most recent version of these data.
