JCSDA COMMUNITY RADIATIVE TRANSFER MODEL
 Background
 
Capability Summary
Community radiative transfer model (CRTM)is used to simulate radiances and radiance gradients (or Jacobians) at the top of atmospheres for satellite and other space-based radiomteors. It is a vital software used in numerical weather prediction model data assimilation systems . This model is developed in support to Joint Center for Satellite Data Assimilation (JCSDA). JCSDA is partnered with NOAA, NASA and DoD
   
CRTM Framework: Why we need it
 
•
  • The radiative transfer problem in CRTM is split into various components (e.g. gaseous absorption, scattering etc). Each component defines its own structure definition and application modules to facilitate independent development.
•
  • Minimize or eliminate potential software conflicts and redundancies.
•
  • Components developed by different groups can “simply” be dropped into the framework.
•
  • Faster implementation of new science and algorithms
•
  • There are User and Developer interfaces, Shared Data interface, Test Software, Utilities/Feedback
