RISComparison of Model Fluxes with Surface and Top-of-the-Atmosphere Observations
Publisher: American Meteorological Society
Abstract: The global observation network of the atmospheric broadband radiation reached an unprecedent extent in 1998 with the simultaneous availability of longwave and shortwave measurements of the Clouds and the Earth?s Radiant ...
Voigt Line Approximation in the ECMWF Radiation Scheme
Publisher: American Meteorological Society
Abstract: The vertical extension of a general circulation model generally requires a modification of the model's highly parameterized radiation scheme in order to include approximately the absorption by lines with a Voigt profile. ...

Publisher: American Meteorological Society
Abstract: The results presented in this paper are a part of those obtained during the ECLATS experiment The broadband radiative characteristics of the Sahelian aerosol layer and the vertical radiative flux divergence within the dust ...
Impact of a New Radiation Package, McRad, in the ECMWF Integrated Forecasting System
Publisher: American Meteorological Society
Abstract: A new radiation package, ?McRad,? has become operational with cycle 32R2 of the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF). McRad includes an improved description ...
