Intercalibration of the GPM Microwave Radiometer Constellation

Uncertainties in radiometer intercalibration associated with variability in geophysical parameters

Spaceborne radiometry plays a major role in weather and climate science and applications. Intercalibrating different radiometers has become an indispensable task for diagnosing instrument performance and integrating constellation data to extend the observational record. Because intercalibration affects both base radiance data and downstream science products, it is critical to examine intercalib...

Polarimetric Microwave Radiometer Calibration

A polarimetric radiometer is a radiometer with the capability to measure the correlation information between vertically and horizontally polarized electric fields. To better understand and calibrate this type of radiometer, several research efforts have been undertaken. 1) All microwave radiometer measurements of brightness temperature (7B) include an additive noise component. The variance and ...

Spaceborne Microwave Radiometry: Calibration, Intercalibration, and Science Applications

Ground-Based Microwave Radiometer Measurements

This particular site and time of year was chosen by ARM because it offers a high probability of clearsky, and also a wide range of integrated water vapor amounts. To supplement the routine observing capabilities during the WVIOP2000, a powerful array of tools for measuring water vapor was deployed at the SGP Central Facility area. A comprehensive suite of airborne in situ and ground-based remote

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...
