RISAssimilation of Infrared Radiance Observations with Sensitivity to Land Surfaces in the Canadian Ensemble–Variational System
Publisher: American Meteorological Society
Abstract: his study highlights recent progress at the Canadian Meteorological Centre in the assimilation of Atmospheric Infrared Sounder (AIRS) and Infrared Atmospheric Sounding Interferometer (IASI) radiance observations that are ...
A Physical Formulation of Atmospheric Transmittances for the Massive Assimilation of Satellite Infrared Radiances
Publisher: American Meteorological Society
Abstract: A continuous assimilation of high-density global satellite observations is required in order to improve numerical weather prediction analyses used to start forecasts. Until now, it was assumed that efficiency requirements ...
Major Advances Foreseen in Humidity Profiling from the Water Vapour Lidar Experiment in Space (WALES)
Publisher: American Meteorological Society
Abstract: The need for an absolute standard for water vapor observations, in the form of a global dataset with high accuracy and good spatial resolution, has long been recognized. The European Space Agency's Water Vapour Lidar ...
Assimilation of Circumpolar Wind Vectors Derived from Highly Elliptical Orbit Imagery: Impact Assessment Based on Observing System Simulation Experiments
Publisher: American Meteorological Society
Abstract: here is a well-recognized spatiotemporal meteorological observation gap at latitudes higher than 55°, especially in the region 55°?70°. A possible solution to address this issue is a constellation of four satellites in a ...
An Intercomparison of Radiation Codes for Retrieving Upper–Tropospheric Humidity in the 6.3–mm Band: A Report from the First GVaP Workshop
Publisher: American Meteorological Society
Abstract: An intercomparison of radiation codes used in retrieving upper?tropospheric humidity (UTH) from observations in the n2 (6.3 mm) water vapor absorption band was performed. This intercomparison is one part of a coordinated ...
