ESA Projects for Radiation Belt Modeling: VALIRENE and RENELLA
Two ESA projects, VALIRENE and RENELLA, focus on radiation belt modeling through detailed evaluation, dataset validation, and model development. The projects aim to enhance existing models, involve European industry, and organize workshops for feedback and collaboration.

Consortia 06/03/2017 Radiation Belt Model Development and Validation: AP9/AE9/SPM models (IRENE, hence VALIRENE) ESA Contract No 4000117974/16/NL/LF DH Consultancy (Belgium, D. Heynderickx): prime contractor Institute of Accelerating Systems and Applications (IASA, Greece; I. Daglis, I. Sandberg, C. Papadimitriou, S.A. Giamini) Kallisto Consultancy (UK, P. Truscott) RadMod Research (UK, F. Lei) Radiation ENvironment at Extremely Low Latitude and Altitude (RENELLA) ESA Contract No 4000118058/16/NL/LF/hh RadMod Research (UK, F. Lei): prime contractor DH Consultancy (Belgium, D. Heynderickx) SPARC (Greece, I. Sandberg, C. Papadimitriou, S.A. Giamini) Kallisto Consultancy (UK, P. Truscott) CSR/UCL (Belgium, M. Cyamukungu, S. Borisov) RBISA (Belgium, N. Messios, E. De Donder) ESA/CNES FP Days, ESTEC 2
VALIRENE objectives 06/03/2017 Detailed evaluation of the AP9/AE9/SPM (IRENE) models Against in situ datasets Against ECSS and other radiation environment models Consolidation and calibration of in situ datasets Ingestion in ODI database Investigation of instrument calibration Cross calibration Evaluation and enhancement of UNILIB/IRBEM Establishment of a toolkit to use the IRENE models for radiation effects studies Involvement of European industry Provide early visibility and invite feedback Organise workshops with industry, could be combined with workshops like SRMDAW ESA/CNES FP Days, ESTEC 3
RENELLA objectives 06/03/2017 XIPE (proposed X-ray mission) environment specification validation Dataset production Selection of primary datasets Ingestion in ODI database Cross-calibration Definition of new LARB (Low Altitude Radiation Belt) proton model Reconstruct PSB97 model for fast revision of XIPE radiation environment Develop methodology for detailed new model development Algorithms for propagation of fluxes to lower altitudes, uni<>omni, differential<>integral, East-West asymmetry Secular change in IGRF, solar cycle PLANETOCOSMICS for modelling support and validation Production of new LARB model and implementation in SPENVIS and IRBEM ESA/CNES FP Days, ESTEC 4
Primary datasets 06/03/2017 LEO: SAMPEX/PET, PROBA-V/EPT, PROBA1/SREM, TSX- 5/CEASE, AZUR/EI-88 MEO: GioveA/MERLIN, GioveB/SREM, GPS GTO: RBSP/HOPE/MAGEIS/REPT, CRRES/MEA/HEEF/PROTEL HEO: INTEGRAL/IREM, XMM/ERMD GEO: GOES/SEM (entire energy range for p+ and e-), LANL/CPA/SOPA/ESP/MPA, Himawari-8,9/SEDA POLAR/CEPPAD ESA/CNES FP Days, ESTEC 5
Data processing 06/03/2017 Processing is built on Open Data Interface (ODI) MySQL database Common set of metadata (CDF/ISTP, SPASE support under development) and variable names (PRBEM, inherited from ESA RERMM project) Dataset configuration files to define processing suites Automatic download of TLEs and orbit propagation where needed Magnetic coordinates using UNILIB Cron/quartz job processing with option for running pre/post- download ingestion scripts Database interfaces in php, Java, Python, IDL, Matlab, Excel REST service ./get_ingest.php sampex_pet_h Version control of processed datasets Final goal: uniform database of calibrated and validated reference datasets ESA/CNES FP Days, ESTEC 6
UNILIB/IRBEM validation 06/03/2017 Comparison of outputs on geographic coordinate sets Spacecraft trajectories Coordinate grids for a series of dates, external field models, Kp Analysis of source codes and algorithms Comparison of magnetic field component outputs to outputs from IAGA codes Develop high level Fortran interface routines for UNILIB, similar to IRBEM Investigate relationship between L and L* Update software codes where required, and feed back to software repositories ESA/CNES FP Days, ESTEC 7
SAMPEX/PET PSB97 model 06/03/2017 ESA/CNES FP Days, ESTEC 8
VALIRENE status 06/03/2017 ODI update to run UNILIB on record varying pitch angle (scalar or vector) Ingestion of most datasets in ODI, with geographic and geomagnetic coordinates (pitch angle dependent where possible) Identification and documentation of all datasets is complete Evaluation of calibration status of instrument data in progress Cross calibration of datasets has started Definition of coordinate grids for UNILIB/IRBEM validation, runs are complete, evaluation in progress Evaluation of UNILIB/IRBEM source code in progress ESA/CNES FP Days, ESTEC 9
RENELLA status 06/03/2017 An update of the SAMPEX/PET PSB97 model was produced Dataset was re-processed after 1997 No limits on local pitch angle The new model was used to Update the XIPE radiation environment specification Compare against original PSB97 model, AP-8, IRENE Production of an IDL toolkit for generating spacecraft trajectories and performing model runs Descriptions of datasets to be used in the study Investigation of calibration issues Analysis of PROBA-V/EPT data has started Conceptual design of new LARB model has started ESA/CNES FP Days, ESTEC 10
