Nimbus 5 (also called Nimbus E or Nimbus V) was a meteorological satellite for research and development of sensing technology. It was the fifth successful launch in a series of the Nimbus program.

The objective of Nimbus 5 was to test and evaluate advanced sensing technology, and to provide improved photographs of cloud formations. There were 6 science instruments aboard Nimbus 5:

1) Infrared Temperature Profile Radiometer (ITPR)
2) Selective Chopper Radiometer (SCR)
3) Nimbus E Microwave Spectrometer (NEMS)
4) Electrically Scanning Microwave Radiometer (ESMR)
5) Surface Composition Mapping Radiometer (SCMR)
6) Temperature/Humidity Infrared Radiometer (THIR)
