RISComments on “New Approach to Calculation of Atmospheric Model Physics: Accurate and Fast Neural Network Emulation of Longwave Radiation in a Climate Model”
Publisher: American Meteorological Society
Model Rain and Clouds over Oceans: Comparison with SSM/I Observations
Publisher: American Meteorological Society
Abstract: A comparison of global model cloud and rain parameterization output with satellite observed radiances was carried out. Hydrometeor profiles from ECMWF operational short-range forecasts were combined with a microwave radiative ...
Evaluation of the Jacobians of Infrared Radiation Models for Variational Data Assimilation
Publisher: American Meteorological Society
Abstract: In this paper, linearized versions of fast infrared radiative transfer schemes for variational data assimilation are studied. A neural network?based infrared broadband radiation model (NeuroFlux) is compared with the ...
AMSU-A Land Surface Emissivity Estimation for Numerical Weather Prediction Assimilation Schemes
Publisher: American Meteorological Society
Abstract: This study describes the work performed at the European Centre for Medium-Range Weather Forecasts (ECMWF) to estimate the microwave land surface emissivities at Advanced Microwave Sounding Unit (AMSU)-A frequencies within ...
High Clouds over Oceans in the ECMWF 15- and 45-Yr Reanalyses
Publisher: American Meteorological Society
Abstract: The reanalysis programs of numerical weather prediction (NWP) centers provide global, comprehensive descriptions of the atmosphere and of the earth?s surface over long periods of time. The high realism of their representation ...
Characteristics of the TOVS Pathfinder Path-B Dataset
Publisher: American Meteorological Society
Abstract: From 1979 to present, sensors aboard the NOAA series of polar meteorological satellites have provided continuous measurements of the earth's surface and atmosphere. One of these sensors, the TIROS-N Operational Vertical ...
Assimilation and Modeling of the Atmospheric Hydrological Cycle in the ECMWF Forecasting System
Publisher: American Meteorological Society
Abstract: Several new types of satellite instrument will provide improved measurements of Earth's hydrological cycle and the humidity of the atmosphere. In an effort to make the best possible use of these data, the modeling and ...
