Validating the microwave sounding unit stratospheric record using GPS occultation

[1] We validate the temperature climatology recorded by the Microwave Sounding Unit with GPS occultation data collected by the GPS/MET experiment. We choose to validate only the lower stratospheric MSU climatology in order to circumvent the wet-dry ambiguity associated with GPS occultation in the midto lower troposphere. We simulate the lower stratospheric channel’s brightness temperature by co...

Atmosphere sounding using GPS radio occultation

Introduction On July 17, 1995 the U.S. Air Force announced “ .. that today the Global Positioning System (GPS) satellite constellation has met all requirements for Full Operational Capability”. Apart from precise positioning GPS signals also can be used to derive characteristic properties of the propagation medium (neutral atmosphere and ionosphere). Onboard the Low-Earth-Orbiting MICROLAB-1 sa...

Investigations of stratospheric temperature regional variability with lidar and Advanced Microwave Sounding Unit

Cross-validation of Advanced Microwave Sounding Unit and lidar for long-term upper-stratospheric temperature monitoring

Intercalibration of microwave sounding unit with short overlaps

NOAA/NESDIS/Center for Satellite Applications and Research has been reprocessing and recalibrating the Microwave Sounding Unit (MSU) observations to generate atmospheric temperature dataset with climate quality. So far, observations from the MSU channels 2, 3, and 4 for NOAA 10, 11, 12, and 14 have been recalibrated using a recently-developed SNO (simultaneously nadir overpasses) sequential non...
