REVIEW AND TEST OF PARAMETERIZATIONS OF ATMOSPHERIC RADIATION 1994
Gerhard Czeplak, Deutscher Wetterdienst
The present technical report documents the data analysis performed in the Subtask. It gives a review of models for the estimation of longwave atmospheric radiation from available meteorological data, ranging from simple models using easily available surface data as input, to sophisticated models for the estimation of spectral longwave radiation from detailed temperature/humidity profiles. The simple models for broadband and spectral longwave radiation on horizontal surfaces are tested against measured data and against a sophisticated spectral model. By both methods, the same models were identified as best performing. Recommendations on the applicability of the simple models are given.
