DART models radiative transfer in the system "Earth - Atmosphere", from visible to thermal infrared. It simulates measurements (images, waveforms,…) of passive and active (lidar) satellite/plane sensors, as well as the radiative budget, for urban and natural landscapes.

These simulations are computed in any experimental (atmosphere, terrain, forest, crop, date, ...) and instrumental (spatial and spectral resolutions, viewing direction ...) configuration.

It is very useful for the study and monitoring of land surfaces from remote sensing measurements.

DART is patented. Paul Sabatier University and CNES support its development in CESBIO since 1992 with the aim that DART becomes a reference model. Paul Sabatier University distributes it as a free licence for research and teaching of remote sensing and radiative balance . It is used by more than one hundred Space Centres (CNES, NASA, ...) and universities (France, USA, Canada, Australia ...).
