Paper Abstract

Fast and accurate radiative transfer model is the key for satellite data analysis, numerical weather prediction, and observation system simulation experiments for climate study applications. We have developed a Principal Component-based radiative transfer model (PCRTM) which can simulate radiative transfer in the cloudy atmosphere from far IR to visible and UV spectral regions quickly and accurately. Multi-scattering of multiple layers of clouds/aerosols is included in the model. A hybrid stream discrete multiple scattering scheme is used to minimizing the number calculation need. The computation speed is 3 to 4 orders of magnitude faster than the medium speed correlated-k option MODTRAN5 and LBLRTM. The PCRTM calculated radiance spectra agree with the Modtran and LBLRTM within 0.02%. Application of this model to various hyperspectral instrument will be shown and discuss.
