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-11 v11.0) is currently available for users via the ROM SAF web pages. The next major release (ROPP-12 v12.0) is currently under development and is hoped to be released to users in 2024.
The ROPP deliverable source code is sub-divided into the following modules
- ropp_utils: low-level utility routines
- ropp_io: I/O support for RO data in a variety of formats, from a variety of sources
- ropp_pp: pre-processor to derive refractivity, bending angle and dry temperature profiles from excess phase and amplitude; 1D and 2D wave optics propagation tools
- ropp_fm: forward models (and associated tangent linear, adjoint and gradient codes)
- ropp_1dvar: 1D-Var tools for retrieving temperature, humidity and electron density, using observations of refractivity, bending angle and differenced bending angles at two frequencies
- ropp_apps: tropopause height and planetary boundary layer height diagnostic tools
Support modules for documenting and testing the source code are:
- ropp_doc: user and project documentation for ROPP
- ropp_test: 'Test Folder' system
Further information on ROPP, including the Release Notes, Change Log, Overview and module User Guides, is available from the ROPP page of the ROM SAF website.
The ROPP Repository
This ROPP Repository can only be accessed by authorized developers - login required.
For instructions on how to access the ROPP repository (authorized users only) see the instructions for developers.
The ROPP Coordination Group (ROPP CG)
This body (formerly The ROPP Governance Group) meets approximately once every six 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 Coordination Group was one of the agreed conclusions from a discussion on the ways of developing ROPP in future.
Here are the ROPP CG Terms of Reference.
