''' Community Radiative Transfer Model ''' (CRTM) is a fast [[atmospheric radiative transfer codes|radiative transfer]] model for calculations of radiances for satellite infrared or microwave nadir scanning radiometers (see [[push broom scanner]]).

Given an atmospheric profile of temperature, variable gas concentrations, cloud and surface properties CRTM calculates [[radiance]]s and [[brightness temperature]]s. The only mandatory inputinputs isin terms of variable gases are [[water vapor]] and [[ozone]]. The range of temperatures and water vapour concentrations over which the optical depth computations are valid depends on the training datasets which were used.

CRTM contains [[forward radiative transfer model|forward]], [[tangent linera radiative transfer model|tangent linear]], [[adjoint radiative transfer model|adjoint]] and K (full Jacobian matrices) versions of the model; the latter three modules forare used in [[Inverse_problem|inversion methods]], including variational assimilation and satellite retrievals.

assimilation or retrieval applications.

One of several applications of CRTM are retrievals of brightness temperature and [[sea surface temperature]] from [[Advanced Very High Resolution Radiometer]] sensor.
