Surface Temperature Data Access and Tools

NASA has surface temperature datasets that help researchers characterize how warm air is over land and water. Access a range of data and data tools such as AppEEARS, HEG: HDF-EOS to GeoTIFF Conversion Tool, and GOES-5 Weather Maps to make the most of surface temperature data.

Featured Surface Temperature Observation Method: AIRS
The Atmospheric Infrared Sounder (AIRS) aboard the Aqua satellite is a hyperspectral instrument that makes daily global measurements of infrared energy reflected by Earth's surface and atmosphere. The data is used to create three-dimensional water vapor and temperature profiles throughout the atmosphere. Meteorologists and other scientists use the data to make weather forecasts and as part of the historical global temperature record.
