DIRECTIONAL SIMULATION OF THERMAL INFRARED RADIATION AND 3D RADIATIVE TRANSFER MODEL OF CANOPY
植被冠层3D辐射传输模型及热辐射方向性模拟

Directional thermal radiation of canopy was studied and the related model was set up.According to the mechanism of radiative transfer,3D canopy scenes were established and the scenes were discretized by differential cells.According to the observed geometric parameters,the radiative transfer of scatter and emission for every internal cell and among cells was calculated.Finally,the directional thermal radiation of canopy could be retrieved from the integral calculation of all differential bodies in the hemisp...
