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...
متن کاملAIRS/AMSU/HSB validation
The Atmospheric Infrared Sounder/Advanced Microwave Sounding Unit/Humidity Sounder for Brazil (AIRS/AMSU/HSB) instrument suite onboard Aqua observes infrared and microwave radiances twice daily over most of the planet. AIRS offers unprecedented radiometric accuracy and signal to noise throughout the thermal infrared. Observations from the combined suite of AIRS, AMSU, and HSB are processed into...
متن کاملThe impact of ozone lines on AMSU-B radiances
[1] The impact of ozone lines on Advanced Microwave Sounding Unit-B (AMSU-B) radiances was investigated using a line-by-line radiative transfer model. The impact is found to be the largest for channel 18 (183.31 ± 1.00 GHz), with a maximum up to about 0.5 K. The channels 17 (150 GHz) and 20 (183.31 ± 7.00 GHz) are also marginally affected by the ozone lines. The magnitude of the impact shows an...
متن کاملAMSU-B Observations of Mixed-Phase Clouds over Land
Measurements from passive microwave satellite instruments such as the Advanced Microwave Sounding Unit B (AMSU-B) are sensitive to both liquid and ice cloud particles. Radiative transfer modeling is exploited to simulate the response of the AMSU-B instrument to mixed-phase clouds over land. The plane-parallel radiative transfer model employed for the study accounts for scattering and absorption...
متن کاملAIRS/AMSU/HSB precipitation estimates
-Precipitation rates (mm/h) with 15and 50-km horizontal resolution are among the initial products of AIRS/AMSU/HSB. They will help identify the meteorological state of the atmosphere and any AIRS soundings potentially contaminated by precipitation. These retrieval methods can also be applied to the AMSU 23-191 GHz data from operational weather satellites such as NOAA-15, -16, and -17. The globa...
