GeoSTAR is a microwave sounding instrument that uses a unique Y-array that allows it to synthesizing a large aperture and monitor water vapor and temperatures below the cloud tops, into geostationary orbit, where it can continuously stare at an entire hemisphere.

  • Instrument Overview
  • The High Altitude MMIC Sounding Radiometer (HAMSR) is an atmospheric sounder intended for aircraft deployment. The primary data products generated with HAMSR consist of calibrated brightness temperatures in two temperature sounding bands and one water vapor sounding bands.

  • AMSU instruments fly on several NASA and NOAA satellites. A typical AMSU is a 15-channel microwave sounder designed primarily to obtain temperature profiles in the upper atmosphere (especially the stratosphere) and to provide a cloud-filtering capability for tropospheric temperature observations.
