• In mid-April 2025, the “Order Files” option of NSIDC DAAC’s Data Access Tool will be retired and replaced with Earthdata Download. Earthdata Download is a native desktop application that enables efficient direct download for orders of any size. To use this new download option, you must install the new version release of Earthdata Download (v1.0.4) available here: https://nasa.github.io/earthdata-download/.
    Additionally, the “Order History” page (https://nsidc.org/order-history) will also be removed two weeks after this update, at the end of April 2025.

Data Set:
Nimbus Temperature-Humidity Infrared Radiometer 6.7 µm Water Vapor Remapped Digital Data Daily L3, GeoTIFF, Version 1
Data Set ID:
NmTHIR67-3G
Data Set Summary:
This data set (NmTHIR67-3G) consists of daily, global composites of radiative temperatures obtained in the 6.7 µm water vapor window (6.5 µm - 7.0 µm) by the Temperature-Humidity Infrared Radiometer (THIR) on board the Nimbus 4 satellite. The THIR 6.7 µm window was used to map the water vapor distribution in the upper troposphere and stratosphere. Data files are GeoTIFF versions of the HDF-formatted equatorial projection file only from the Nimbus Temperature-Humidity Infrared Radiometer 6.7 µm Water Vapor Remapped Digital Data Daily, HDF5 (NmTHIR67-3H) data set.
