Annual mean top of the atmosphere longwave cloud forcing for the ECMWF forecast model without RRTMG/McICA (top left contour) and with RRTMG/McICA (top right contour), CERES observations (center contours) and differences between the models and measurement (bottom contours). Line plots show zonal mean longwave cloud forcing (top), and longitude plots averaged over the extra tropics (center) and the tropics (bottom) for each model (black) and the observation (red) (from Morcrette et al., 2008).
