Nimbus Temperature-Humidity Infrared Radiometer 11.5 µm Grayscale Swath Data L1, TIFF V001

This data set consists of daily, global grayscale TIFF images derived from radiative temperatures measured in the 11.5 µm window (10.5 µm - 12.5 µm). These data were detected by the Temperature-Humidity Infrared Radiometer (THIR) on board the Nimbus 4, Nimbus 5, and Nimbus 6 satellites, respectively, during 1970-1971, 1973-1975 and 1975. The Nimbus satellites used the THIR 11.5 µm window to measure cloud top or surface temperatures. Note: This data set is not georeferenced and contains some gaps in temporal coverage because of missing data.
