ROPP

This is the feature request, issue and bug tracking web site for the Radio Occultation Processing Package (ROPP).

ROPP is a software package designed to assist users to assimilate radio occultation data from any RO mission into NWP and other models. The package is being developed through the EUMETSAT ​GRAS SAF.

The latest full release of ROPP (ROPP-1 v1.2) is currently available for users via the ​GRAS-SAF Archive and Retrieval Facility.

The ROPP deliverable source code is sub-divided into modules:

• ropp_tools : low-level utility routines
• ropp_io : I/O support for RO data in netCDF and BUFR files
• ropp_pp : pre-processor (e.g. to derive refractivity profiles from bending angle profiles (from ROPP-2))
• ropp_fm : forward models (and associated tangent linear, adjoint & gradient code)
• ropp_1dvar : 1D-Var retrieval & minimizer

Further information on ROPP, including the ​ROPP User Guide, is available from the ​GRAS-SAF.
