Several models are developed at CESBIO

 

Earth observation from space relies on radiation measurement. This is essential for studying many Earth phenomena (e.g., photosynthesis, Earth energy budget) and applications (forestry, agriculture, urbanism,...). However, the way radiation interacts with our planet and how it builds up satellite images should be better known. This stresses the need to develop new radiative transfer models that simulate more accurately radiation interaction and satellite images.

 

   
 
  • DART (Discrete Anisotropic Radiative Transfer) model is developed at CESBIO since 1992. It simulates 3-D radiative transfer in the "Earth-Atmosphere"system with an innovative ray tracing method that combines the exact kernel and discrete ordinate techniques, simultaneously in several wavelengths, from the visible to the thermal infrared domains (0.3mm - 15mm). Computer scenes are natural and urban landscapes, with / without topography and atmosphere. A Graphic User Interface (GUI) allows one to input and display computer scene parameters and simulations.
