Description

This data set consists of daily, global grayscale TIFF images derived from radiative temperatures measured in the 6.7 µm window (6.5 µm - 7.0 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 6.7 µm window to map the water vapor distribution in the upper troposphere and stratosphere. Note: This data set is not georeferenced and there are some gaps in temporal coverage because of missing data.
