Current 3D Atmospheric Data Model

Temp(z)

Pressure(z)

%RelHum(z)

%H2O(z)

etc….

Given 3D grid of cells, each

with its own temp, pressure,

humidity, H20 and aerosol

concentrations, etc. …

Run SigSim Modtran/Radtran Libraries on vertical path through each column of cells …

Extract path-and angle-dependent transmissions, path radiances, and scattering cross sections per layer (cell )…

… and convert them to path-and-angle- independent extinction, radiance, and scattering coefficients per layer (cell)

NOTE : Spectral !!
