VO1/VO2 MARS INFRARED THERMAL MAPPER RESAMPLED DATA V1.0

This data set contains the Infrared Thermal Mapping (IRTM) data of Mars acquired by the Viking orbiters. The database contains the time, geometry, and radiative parameters obtained by the IRTM instrument. Included in the database for each measurement are model temperatures of Mars represent the average Martian response to the temporal variation of insolation. The reference 'Thermal and Albedo Mapping of Mars during the Viking Primary Mission', Journal of Geophysical Research, Vol. 82, No. 28, 1977, describes how the thermal emission and reflected energy measured by the various channels on the Infrared Thermal Mapper are used to reveal wide variations in the Martian surface properties. There is a description of how the surface thermal inertias are mapped and correlated with the surficial geologic units. The derivation of model and surface temperatures are described. The data set includes latitude and longitude for each measured point, as well as emission angle, solar incidence angle, the position of the sun, and other parameters that help to locate the position of the spacecraft relative to Mars. (For further information see the Confidence_Level_Note).
