RADIOMETRE HYPERFREQUENCE BALAYAGE MULTIBANDE [4 records]

Record 1 2010-03-08

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Oceanography
CONT

The Multi-Channel Sea Surface Temperature (MCSST) data are derived from the 5-channel Advanced Very High Resolution Radiometers (AVHRR) on board the NOAA -7, -9. -11 and -14 polar orbiting satellites. Weekly averaged data for both the ascending pass (daytime) and descending pass (nighttime) are provided on an equal-angle grid of 2048 pixels longitude by 1024 pixels latitude (nominally referred to as the 18km resolution). Data are provided in Hierarchical Data Format and in Raw Binary Format.

CONT

The multichannel sea surface temperature algorithm (MCSST) has been used to routinely calculate SSTs using a split window approach. Currently this algorithm is applied by the Naval Oceanographic Office (NAVOCEANO) to calculate SSTs at a near real-time rate.

OBS

sea surface temperature: The temperature of the layer of sea water nearest the atmosphere.

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
  • Remote Sensing
DEF

A scanning radiometer that measures microwave radiation in five wavelength bands and 10 channels to determine the wind, sea surface temperature and roughness, cloud water content, precipitation, snow cover and sea ice.

CONT

The scanning multichannel microwave radiometer (SMMR) is an imaging 5-frequency radiometer ... It measures dual-polarized microwave radiances from the earth's atmosphere and surface, primarily for the purpose of deriving global and nearly all-weather measurements of sea surface temperature, wind speed, and atmospheric liquid water and water vapor.

OBS

This radiometer flew on Seasat (launched in June 1978) and Nimbus-7 (launched in October 1978).
