Description

This data set consists of daily, global grayscale TIFF images measured in the 6.7 µm window (6.5 µm - 7.0 µm) and the 11.5 µm window (10.5 µm - 12.5 µm) by the Temperature-Humidity Infrared Radiometer (THIR) on board the Nimbus 7 satellite. Each data granule is a daytime or nighttime global composite of all the swaths in a day. Note: This data set is not georeferenced and there are some gaps in the temporal coverage because of missing data.
