Nimbus-6 THIR

The Nimbus-6 satellite was successfully launched on June 12, 1975. The Nimbus-6 Temperature-Humidity Infrared Radiometer (THIR) experiment was a follow-on to the instruments flown on Nimbus-5 and Nimbus-4.

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

  • 11.5 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-6 users' guide under the Documentation link on the menu bar.

You may download the Nimbus-6 THIR 6.7 and 11.5 micron channel data products by selecting the "Data Holdings" link on the menu bar.
