Nimbus-5 THIR

The Nimbus-5 satellite was successfully launched on December 11, 1972. The Nimbus-5 Temperature-Humidity Infrared Radiometer (THIR) experiment was the follow-on instrument flown on Nimbus-4.

THIR is a two channel high resolution scanning radiometer designed to perform two major functions:

  • 10.5 – 12.5 micron channel provides both day and night cloud top or surface temperatures. The ground resolution at the sub-point is 8km and operates day and night.

  • 6.7 micron channel gives information on the moisture content of the upper troposphere and stratosphere and the location of jet streams and frontal systems. The water vapor channel has a resolution of the sub-point is 22 km and operates mostly at night.

More information can be found in the README file or Nimbus-5 Users' Guide under the Documentation link on the menu bar.

You may download the Nimbus-5 THIR data products by selecting the "Data Holdings" link on the menu bar.
