ESMR/Nimbus-5 Images of Brightness Temperature on 70 mm Film V001 (ESMRN5IM)

Additional information can be found in "The Nimbus 5 User's Guide." The primary objectives of the ESMR experiment were: (1) to derive the liquid water content of clouds from brightness temperatures over oceans, (2) to observe differences between sea ice and the open sea over the polar caps, and (3) to test the feasibility of inferring surface composition and soil moisture. To accomplish these objectives, the ESMR was capable of continuous global mapping of the 1.55-cm (19.36 GHz) microwave radiation emitted by the earth/atmosphere system, and could function even in the presence of cloud conditions that block conventional satellite infrared sensors.

The ESMR instrument made measurements from Dec. 11, 1972 until May 16, 1977. This product was previously available from the NSSDC with the identifier ESAD-00192 (old ID 72-097A-04C).
