Variability of Moisture in the Upper Troposphere As Inferred from TOVS Satellite Observations and the ECMWF Model Analyses in 1989
Publisher: American Meteorological Society
Abstract: Large-scale variability of moisture in the upper troposphere is examined using TIROS (Television Infrared Observation Satellite) Operational Vertical Sounder (TOYS) satellite observations and ECMWF model analyses from 1989 ...
The Impact of Conventional Surface Data upon VAS Regression Retrievals in the Lower Troposphere
Publisher: American Meteorological Society
Abstract: Surface temperature and dewpoint reports are added to the infrared radiances from the VISSR Atmospheric Sounder (VAS) in order to improve the retrieval of temperature and moisture profiles in the lower troposphere. The ...
VISSR Atmospheric Sounder (VAS) Simulation Experiment for a Severe Storm Environment
Publisher: American Meteorological Society
Abstract: The GOES satellites launched in the 1980's are carrying an instrument called the VISSR Atmospheric Sounder (VAS), which is designed to provide temperature and moisture profile-sounding capability for mesoscale weather ...
VAS Sounding Images of Atmospheric Stability Parameters
Publisher: American Meteorological Society
Abstract: Local forecasts often rely upon the extrapolation of trends seen in images of clouds from the GOES satellite. This work presents correspondingly high resolution images of atmospheric soundings calculated from the VAS ...
Low-Level Water Vapor Fields from the VISSR Atmospheric Sounder (VAS) “Split Window” Channels
Publisher: American Meteorological Society
Abstract: A simple physical algorithm is developed which calculates the water vapor content of the lower troposphere from the 11 and 12 ?m (split window) channels on the VISSR Atmospheric Sounder (VAS) on the Geostationary Operational ...
Evaluation of the Upper-Tropospheric Moisture Climatology in a General Circulation Model Using TOVS Radiance Observations
Publisher: American Meteorological Society
Abstract: TOVS satellite observations are used to evaluate the upper-tropospheric (400?200 mb) moisture distribution simulated by the GLA GCM in a 10-yr (1979?1988) integration produced for the Atmospheric Model Inter-comparison ...
Optimized Retrievals of Precipitable Water from the VAS “Split Window”
Publisher: American Meteorological Society
Abstract: Precipitable water fields have been retrieved from the VISSR Atmospheric Sounder (VAS) using a radiation transfer model for the differential water vapor absorption between the 11 and 12 ?m ?split window? channels. Previous ...
Assessment of VAS Soundings in the Analysis of a Preconvective Environment
Publisher: American Meteorological Society
Abstract: Retrievals from the VISSR Atmospheric Sounder (VAS) an combined with conventional data to assess the impact of geosynchronous satellite soundings upon the analysis of a pre-convective environment over the central United ...
