Stratospheric Temperature Climate Data Record from Merged SSU and AMSU-A Observations

Stratospheric and tropospheric SSU/MSU temperature trends

A decadal microwave record of tropical air temperature from AMSU-A/aqua observations

Atmospheric temperature is one of the most important climate variables. This observational study presents detailed descriptions of the temperature variability imprinted in the 9-year brightness temperature data acquired by the Advanced Microwave Sounding UnitInstrument A (AMSU-A) aboard Aqua since September 2002 over tropical oceans. A non-linear, adaptive method called the Ensemble Joint Multi...

Near-Surface Air Temperature Retrieval Derived from AMSU-A and Sea Surface Temperature Observations

A 10-m air temperature (Ta) retrieval using Advanced Microwave Sounding Unit A (AMSU-A) and satellite-derived sea surface temperature (Ts) observations is presented. The multivariable linear regression retrieval uses AMSU-A brightness temperatures from the 52.8and 53.6-GHz channels and satellite-derived daily sea surface temperatures to determine Ta. A regression error of 0.838C using 841 match...

Classification of hydrometeors using microwave brightness temperature data from AMSU-B over Iran

The Advanced Microwave Sounding Unit-B (AMSU-B) installed on the NOAA-15, 16, and 17 satellites, is the new generation of a series of microwave imagers/sounders that can sense atmospheric moisture and other hydrometeors through clouds. This paper demonstrates the potential of multi-frequency AMSU-B data for classifying different types of hydrometeors. Ten types of these hydrometers have been co...

Retrieval of temperature and moisture profiles from AMSU-A and AMSU-B measurements

The NOAA-15 weather satellite carries the Advanced Microwave Sounding Units-A and -B (AMSU-A, AMSU-B) which measure thermal emission from an atmospheric oxygen band, two water lines, and several window frequencies. An iterated minimum-variance algorithm retrieves profiles of temperature and humidity in the atmosphere from this data. Relative humidity is converted into absolute humidity with use...
