Description

This data set (NmTHIR115-3G) consists of daily, global composites of radiative temperatures obtained in the 11.5 µm window (10.5 µm - 12.5 µm) by the Temperature-Humidity Infrared Radiometer (THIR) on board the Nimbus 4 satellite. This window was used to measure cloud top or surface temperatures. Data files are GeoTIFF versions of the HDF-formatted equatorial projection file <em>only</em> from the Nimbus Temperature-Humidity Infrared Radiometer 11.5 µm Remapped Digital Data Daily L3, HDF5 (<a href="http://dx.doi.org/10.5067/NIMBUS/NmTHIR115-3H">NmTHIR115-3H</a>) data set.
