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 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...
متن کاملImaging gravity waves in lower stratospheric AMSU-A radiances, Part 2: Validation case study
Two-dimensional radiance maps from Channel 9 (∼60–90 hPa) of the Advanced Microwave Sounding Unit (AMSU-A), acquired over southern Scandinavia on 14 January 2003, show plane-wave-like oscillations with a wavelength λh of ∼400–500 km and peak brightness temperature amplitudes of up to 0.9 K. The wave-like pattern is observed in AMSU-A radiances from 8 overpasses of this region by 4 different sat...
متن کاملImaging gravity waves in lower stratospheric AMSU-A radiances, Part 1: Simple forward model
Using a simplified model of in-orbit radiance acquisition by the Advanced Microwave Sounding Unit (AMSU-A), we derive three-dimensional temperature weighting functions for Channel 9 measurements (peaking at ∼60–90 hPa) at all 30 cross-track beam positions and use them to investigate the sensitivity of these radiances to gravity waves. The vertical widths of the weighting functions limit detecti...
