Two-Channel Infrared Radiometer

NSSDC ID: 1973-085A-06
Mission Name: Mariner 10
Principal Investigator: Mr. Stillman C. Chase, Jr.

Description

The infrared radiometer utilized two channels, 22--39 micrometers (80--500 K) and 10--17 micrometers (200--650 K), to observe the thermal emission from Venus and Mercury in two broad spectral bands. The infrared thermal emission from the surface of Mercury between late afternoon and early morning (local time) and deviations from the average thermal behavior of the surface were measured. Measurements were also made of the brightness temperatures of Cytherian cloud tops and limb darkening phenomena. Attempts were made to correlate unusual temperature variations with photographs and measurements by other instruments to identify mountains, valleys, volcanoes, and unusual surface materials.
