Nimbus-6 SCAMS

Contributors: tonyr

The Nimbus-6 satellite was successfully launched on June 12, 1975. The Nimbus-6 Scanning Microwave Spectrometer (SCAMS) experiment was follow on to the successful Nimbus-E Microwave Scanner (NEMS) flown on Nimbus-5.

SCAMS continuously monitored emitted microwave radiation at frequencies of 22.235, 31.65, 52.85, 53.85 and 55.45 GHz.  The instrument scanned plus or minus 45 deg normal to the orbital plane with a 10-deg field of view. The swath width is about 2400 km, with a spatial resolution of 145 km at nadir to about 330 km at the scan edges. Measurement objectives include:

  • Atmospheric temperature profiles - 52.85, 53.85 and 55.45 GHz (O2 absorption band)

  • Water vapor and cloud liquid content - 22.235 and 31.65 GHz (H2O bands)

More information can be found in the README file or Nimbus-6 Users' Guide under the Documentation link on the menu bar.

You may download the Nimbus-6 SCAMS data product by selecting the "Data Holdings" link on the menu bar.
