Unified Linearized Vector Radiative Transfer Model: aiming to a testbed for remote sensing of atmosphere, land, and ocean.
What Is UNL-VRTM?
UNL-VRTM was specifically designed for the simulation of atmospheric remote sensing observations and for the inversion of aerosol, gas, cloud, and/or surface properties from these observations. It is applied by research groups around the world to a wide range of Earth remote sensing problems. UNL-VRTM comprises VLIDORT for radiative transfer, a linearized Mie and a linearized T-Matrix code for aerosol single scattering, a Rayleigh scattering module, and line-by-line (LBL) gas absorption calculation with HITRAN database:
