Nimbus-3 Level 2 Medium Resolution Infrared Radiometer (MRIR) V001 (MRIRN3L2) at GES DISCEntry ID: GES_DISC_MRIRN3L2_V001
Abstract: The Nimbus III Medium Resolution Infrared Radiometer (MRIR) was designed to measure electromagnetic radiation emitted and reflected from the earth and its atmosphere at 5 wavelengths.
The five wavelengths regions are as follows:
6.5 to 7.0 microns- This channel covers the 6.7 micron water vapor absorption band. Its purpose is to provide information on water vapor ... distribution in the upper troposphere and, in conjunction with the other channels to provide relative humidities at these altitudes
10 to 11 microns - microns- This channel measures surface or near surface temperatures over clear portions of the atmosphere. It also provides cloud cover and cloud height information (day and night).
14.5 to 15.5 microns – This channel, centered about the strong absorption band of C02 at 15 microns, measures radiation which emanates primarily from the stratosphere.
20 to 23 microns – This channel yields data from the spectral region containing the broad rotational absorption bands of water vapor. This provides similar information to the 6.5 to 7.0 micron channel except that the flux is mostly radiated from lower in the atmosphere.
0.2 to 4.0 microns – This channel covers more than 99% of the solar spectrum and yields information on the intensity of the reflected solar energy from the earth and its atmosphere.
The Nimbus III MRIR data are stored in a binary TAP format (proprietary Tape emulated format).
The MRIR instrument was launched on April 14 1969 and was operational from 15 April 1969 through 4 February 1970.
