The all-weather, global determination of sea surface temperature SST was identified as a requirement needed to support Navy operations. The acceptable SST accuracy is or - 1.0 K with a surface resolution of 25 km. Investigations of the phenomenology and technology of remote passive microwave sensing of the ocean environment over the past decade beginning with the Navy specification of the Remote Ocean-surface Measurement System, through the NASA launched Scanning Multichannel Microwave Radiometer flown on both SEASAT and NIMBUS-7 to the planning by NASA of the Large Antenna Multichannel Microwave Radiometer, and development of the Mission Sensor MicrowaveImager SSMI to be flown in 1985 by the NavyAir Force, have demonstrated that this objective is presently attainable. Preliminary specifications and trade-off studies have been conducted to define the frequency, polarization, scan geometry, antenna size and other essential parameters, as well as the retrieval algorithms and spacecraft interface requirements, of the Low Frequency Microwave Radiometer LFMR. As presently planned, the LFMR will be a stand alone system completely independent of the SSMI but with a 30 rpm conical scan at 53.1 deg incidence angle identical to the SSMI. It will be a dual-frequency system at 5.2 and 10.4 GHz using a 5.9 meter deployable mesh surface antenna. It is to be flown on the Navy-Remote Ocean Sensing System satellite scheduled to be launched in late 1988. Author
