Viking Orbiter MAWD

Data from the Mars Atmospheric Water Detector is archived at the PDS Atmospheres Node. The following description is from the Atmospheres Node catalog.

This data set consists of the raster-averaged radiant intensities and associated data parameters produced from data acquired by the Mars Atmospheric Water Detectors (MAWD) onboard the Viking Orbiters. The basic observations give temporal coverage spanning just over two martian years and variable, but extensive, spatial coverage of the planet. MAWD was a five-channel grating spectrometer measuring solar radiation reflected from the surface and atmosphere of Mars in and out of water vapor bands in the 1.4 micrometer spectral interval. The data set described here contains the solar reflected radiant intensities (i.e., radiances) measured by MAWD, derived water vapor column abundances, a derived '1.4-micrometer brightness', and ancillary data (e.g., viewing geometry, surface elevation and airmass).
