文摘
- •
Revised scheme for calculation of synthetic Meteosat SEVIRI brightness temperatures
- •
Improved consistency between model-internal and external microphysical formulations
- •
Up to 10 K systematic changes in brightness temperatures for semi-transparent cirrus
- •
Crystal size perturbations of 20% induce up to 4 K brightness temperature deviations.
- •
Cold COSMO-DE bias is partly attributed to cirrus-radiation uncertainties.
