On the Equivalence between Radiance and Retrieval Assimilation
Publisher: American Meteorological Society
Abstract: he need for consistent assimilation of satellite measurements for numerical weather prediction led operational meteorological centers to assimilate satellite radiances directly using variational data assimilation systems. ...
Optimal Ensemble-Based Selection of Channels from Advanced Sounders in the Presence of Cloud
Publisher: American Meteorological Society
Abstract: his study aims to illustrate a general procedure based on well-known information theory concepts to select the channels from advanced satellite sounders that are most advantageous to assimilate both in clear-sky and overcast ...
Understanding Atmospheric Motion Vector Vertical Representativity Using a Simulation Study and First-Guess Departure Statistics
Publisher: American Meteorological Society
Abstract: tmospheric motion vectors (AMVs) have been produced for decades and remain an important source of wind information. Many studies have suggested that the traditional interpretation of AMVs as representative of the wind at ...
Use of the Information Content in Satellite Measurements for an Efficient Interface to Data Assimilation
Publisher: American Meteorological Society
Abstract: Satellite observations are the most assimilated data type by operational meteorological centers. Spaceborne instruments can make measurements all over the globe and provide observations for assimilation even where the ...
A Spatial View of Ensemble Spread in Convection Permitting Ensembles
Publisher: American Meteorological Society
Abstract: ith movement toward kilometer-scale ensembles, new techniques are needed for their characterization. A new methodology is presented for detailed spatial ensemble characterization using the fractions skill score (FSS). To ...
