Thermal Emission Spectra from the Infrared Interferometer Spectrometer (IRIS) on Nimbus 3 and 4

Entry ID: NIMBUS_IRIS

[ Update this Record ]

Summary

Abstract: The Infrared Interferometer Spectrometer (IRIS) on Nimbus 3 and 4 measured
thermal emission of the Earth and its atmosphere in the spectral range of
5 to 20 micrometers, with nominal spectral resolutions of 5 and 1.4 cm**-1,
respectively. Interferograms were Fourier transformed into spectra.

On the archival tapes are calibrated atmospheric spectra along with reference
calibration, average instrument temperature, summary information for each
orbital pass, and documentation. From these spectra, vertical profiles of
temperature, water vapor, and ozone data may be derived.

The original 9-track, 1600 bpi magnetic tapes are being restored at NSSDC
onto 6250 bpi tapes.
