1 JCSDA Community Radiative Transfer Model (CRTM) Framework JCSDA 3 rd Workshop on Satellite Data Assimilation, 20-21 April 2005 Yong Han, Quanhua Liu, Paul van Delst Overview User Interface – Forward, tangent-linear, adjoint, K-matrix (Jacobian) – Public data structures Developer Interface ...
The model comprises four major modules for calculations of the atmospheric transmittance, surface emissivity/reflectivity, cloud/aerosol optical property and RT solution, respectively. In the atmospheric transmittance module, on top is the multiple transmittance algorithm framework, which allows different ...
A key part of the preparation is assimilation of the data from heritage instruments and preparation of the JCSDA Community Radiative Transfer Model (CRTM) for the NPOESS and GOES-R instruments. Data from the heritage instruments have been assimilated and used within NCEP, GMAO and NRL analysis ...
This effort is aimed to provide a mechanism to consider particle mass density variation in the microwave scattering coefficients implemented in the Community Radiative Transfer Model (CRTM). The stochastic model applies a bicontinuous random medium algorithm to a simple base shape and uses the Finite-...
A high priority activity of the JCSDA was to establish a fast Community Radiative Transfer Model (CRTM) for all AIRS channels. The CRTM model developed was OPTRAN8 and this was completed and tested pre-launch. The AIRS data has been used subsequently in the Global Data Assimilation System (...
