Abstract

It is important for the improvement of numerical weather forecast accuracy to reseach the simulation error of rapid radiative transfer model. Using the radiosonde data as the input of rapid radiant transfer model CRTM, the simulation error of infrared channels observation of VIRR on FY-3A is analyzed. The distribution of model biases in radiance of three infrared channels are approximate normal ditribution, which means the the model simulation is consistent with obervation. And the simulation errors in different seasons, for different types of ground objects, in different climate zones and at different altitudes are discussed.
