| Description |
| Dear ROM SAF ROPP User Issued: 2026-01-14 14:58 UTC The ROM SAF announces the release of ROPP-12.0, the latest update of the Radio Occultation Processing Package (ROPP). The main differences from the previous release, ROPP-11.3, are the following: - Addition of a new tool combining the Abel inversion and the Chapman model with a linearly increasing scale height to retrieve ionospheric electron density vertical profiles (EDVPs) from truncated sounding radio occultation data (AVHIRO2). - Implementation of cubic spline interpolation as a new option for interpolation between height, geopotential height and impact height layers in the bending angle and refractivity forward models. - Inclusion of the kappa formula for residual ionospheric correction. - Improvements of the QC and the first guess settings of the ionospheric 1D-Var. - Improved processing of EUMETSAT level 1a data (for all missions). - Recoding of routines to handle ingested GNSS frequencies (e.g. from Sentinel-6) rather than assuming default L1 and L2 frequencies. - Introduction of code to read Sentinel-6 RO data from EUMETSAT. - Enable encoding/decoding of the new satellite sub-identifier and alternative sub-centre in BUFR. - Building of separate BUFR encode/decode tools for each BUFR library that is available. - Improve ROPP IO and ROPP UTILS core testing, which brings the I/O and UTILS module in line with the other modules’ core tests. - Update/change of the build system. Details of all changes, together with the updated software and documentation, are available on the ROPP download website: https://rom-saf.eumetsat.int/ropp/files.php. Kind regards The ROM SAF Team |
