Characterization and correction of a drift in calibration of the TOPEX microwave radiometer

نویسنده

چکیده

Characterization of the drift in the 18-GHz brightness temperature (TB) measured by the TOPEX microwave radiometer (TMR) is presented. The appropriate correction is not a constant drift but varies with TB. Using this correction results in a more accurate path delay retrieval that varies appropriately with cloud cover and surface wind speed.

Detection of calibration drifts in spaceborne microwave radiometers using a vicarious cold reference

The coldest possible brightness temperatures observed by a downward-looking microwave radiometer from space are often produced by calm oceans under cloud-free skies and very low humidity. This set of conditions tends to occur with sufficient regularity that an orbiting radiometer will accumulate a useful number of observations within a period of a few days to weeks. Histograms of the radiometer...

TOPEX microwave radiometer performance evaluation, 1992-1998

The stability and accuracy of the TOPEX Microwave Radiometer (TMR) measurement of the atmospheric path delay due to water vapor is assessed over the interval from launch (August 1992) through June 1998. Detailed global comparisons are made with path delays derived from the special sensor microwave imager (SSM/I) instruments and a network of 15 island radiosondes. The results provide consistent ...

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 ...

A Multipoint Correction Method for Environmental Temperature Changes in Airborne Double-Antenna Microwave Radiometers

This manuscript describes a new type Ka-band airborne double-antenna microwave radiometer (ADAMR) designed for detecting atmospheric supercooled water content (SCWC). The source of the measurement error is investigated by analyzing the model of the system gain factor and the principle of the auto-gain compensative technique utilized in the radiometer. Then, a multipoint temperature correction m...

Aquarius engineering phase on-orbit TA calibration

Aquarius is a passive microwave radiometer operating at L-band that is designed to measure ocean salinity. Launched in June 2011, the instrument has since been the subject of on-orbit calibration to evaluate its performance and characterize its stability. This study addresses external calibration methods, using observed antenna temperatures to characterize instrument behavior by computing the o...
