ROPP Software Deliverable
The GRAS SAF provides software modules, with associated user guides, which implement procedures to assist the user in assimilating GRAS profiles into NWP and other models.
- 1D-var pre-retrieval from refractivity and a user's background profile
- 3D-var assimilation tools - forward operators and their adjoints
Since end-users' operational systems have specific software standards, interfacing requirements and other constraints, the GRAS SAF software deliverables cannot be treated as 'black box' modules. Some modification by users for their specific operational environment is to be expected.
