= 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 [http://www.grassaf.org/ GRAS SAF]. The latest full release of ROPP ('''ROPP-1 v1.2''') is currently available for users via the [http://garf.grassaf.org/index.php GRAS-SAF Archive and Retrieval Facility (GARF)]. ROPP-2 ('''v2.0''') is currently under beta-testing and is expected to be released to users in December 2008. 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)) [https://trac.grassaf.org/ropp/wiki/ropp_pp_tree tree] * '''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_build''' : build and configure scripts for ROPP and dependency packages Further information on ROPP, including the [http://garf.grassaf.org/user-documents/gras_ropp_ug.pdf ROPP User Guide], is available from [http://garf.grassaf.org/software.php GARF]. == The ROPP Repository == This ROPP Repository can only be accessed by authorized developers - [https://trac.grassaf.org/ropp/login login required].
