ROPP software

This is the feature request, issue and bug tracking wiki website 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 ​ROM SAF. The ROM SAF project wiki page for team members is located ​here.

The latest full release of ROPP (ROPP-7 v7.0) is currently available for users via the ​ROM SAF web pages. The next major release ROPP-8 (v8.0) is currently under development and is expected to be released to users in Q4 2014.

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

• ropp_utils : low-level utility routines
• ropp_io : I/O support for RO data in netCDF and BUFR files
• ropp_pp : preprocessor to derive refractivity and bending angle profiles from excess phase and amplitude
• ropp_fm : forward models (and associated tangent linear, adjoint & gradient code)
• ropp_1dvar : 1D-Var retrieval & minimizer

Supporting modules for documentation, testing and building the source are:

• ropp_doc : user and project documentation for ROPP
• ropp_test : 'Test Folder' system
• ropp_bld : build and configure scripts for ROPP and dependency packages

Further information on ROPP, including the Release Notes, Overview and module User Guides, is available from the ​ROPP page of the ROM SAF website.

The ROPP Governance Group (ROPP GG)

This body meets approximately once every two months to discuss forthcoming ROPP developments, to set priorities for implementation, and to provide a forum for general liaison between developers. Representatives from each ROM SAF Cooperating Entity are invited.

The formation of an ROPP Governance Group was one of the agreed conclusions from a discussion on the ways of developing ROPP in future.

Here are the ROPP GG terms of reference.
