RISExperiments in the Four-Dimensional Assimilation of Nimbus 4 SIRS Data
Publisher: American Meteorological Society
Abstract: Temperature data derived from Nimbus 4 SIRS radiance measurements have been used in four-dimensional assimilation experiments with a simple two-level primitive equation model. Data are inserted into a running forecast on ...
GOES-VAS Simultaneous Temperature-Moisture Retrieval Algorithm
Publisher: American Meteorological Society
Abstract: Vertical soundings of temperature and moisture derived from the GOES VISSR Atmospheric Sounder (VAS) measurements have been produced operationally since summer 1987 at the VAS Data Utilization Center (VDUC). The algorithm ...
The Anticipated Sounding Capabilities of GOES-I and Beyond
Publisher: American Meteorological Society
Abstract: One aspect of the modernized observational capability of the National Weather Service will be geostationary sounding of temperature and moisture from GOES-I, currently scheduled for launch in 1992. The capability has evolved ...
The Use of High Horizontal Resolution Satellite Temperature and Moisture Profiles to Initialize a Mesoscale Numerical Weather Prediction Model—A Severe Weather Event Case Study
Publisher: American Meteorological Society
Abstract: This note describes the assimilation of sub-synoptic resolution satellite-derived temperature and moisture profiles into a mesoscale numerical weather prediction model, intended for forecasting the environment of organized ...
The Impact of Satellite-Derived Temperature Profiles on the Energetics of NMC Analyses and Forecasts during the August 1975 Data Systems Test
Publisher: American Meteorological Society
Abstract: Standard atmospheric energy budget computations are made for three distinct sets of Northern Hemisphere synoptic analyses prepared from data gathered during the August 1975 Data Systems Test. The first analysis set (System ...
Recursive Filter Objective Analysis of Meteorological Fields: Applications to NESDIS Operational Processing
Publisher: American Meteorological Society
Abstract: A recursive filter objective analysis method is described. It is a "successive approximation" system with the particular feature of locally varying scaling, making it especially appropriate for dealing with inhomogeneous ...
A Note on Water-Vapor Wind Tracking Using VAS Data on McIDAs
Publisher: American Meteorological Society
Abstract: Eleven data sets where water-vapor winds were obtained from the GOES-5 6.7-micrometer measurement over the United States are compared with rawinsondes. Over 2OOO point comparisons are made for: a) an arbitrary height ...
A Study of Satellite-derived Moisture with Emphasis on the Gulf of Mexico
Publisher: American Meteorological Society
Abstract: Visible-Infrared Spin Scan Radiometer (VISSR) Atmospheric Sounder (VAS) moisture retrievals are compared to the National Meteorological Center Regional Analysis and Forecast System (RAFS) 12-h forecast and to 1200 UTC ...
Adjustment of VAS and RAOB Geopotential Analysis Using Quasi-Geostrophic constraints
Publisher: American Meteorological Society
Abstract: Comparisons between geopotential analyses derived from rawinsondes (RAOB) and the VISSR Atmospheric Sounder (VAS) generally exhibit differences that are ultimately related to the horizontal density and placement of the ...
Determination of Moisture From NOAA Polar Orbiting Satellite Sounding Radiances
Publisher: American Meteorological Society
Abstract: A method is presented for deducing lower troposphere moisture fields from radiances measured by the operational polar orbiting NOAA satellites. Statistical evaluation of the technique demonstrates the viability of the ...
