CCMC begins collaboration with ESA's SPENVIS Team


The CCMC is now collaborating with ESA’s SPace ENVironment Information System (SPENVIS) team to interlink space weather models and tools hosted by each group. With the help of the SPENVIS team, the CCMC has used the SPENVIS-NG (Next Generation) Python API (Application Programming Interface) to run their first SPENVIS model remotely, displaying the results at the CCMC (see “Model and results” section below).

These results are an initial success toward creating an international, global system of interlinked web resources, one in which the CCMC and SPENVIS teams could mutually leverage each other’s models, services, APIs, and back-end systems to develop new capabilities for the community. The next steps will include using the Python API to execute SPENVIS model runs automatically, generating self-updating displays in CCMC systems, for example, the Integrated Space Weather Analysis (iSWA) system.

Model and results

The target model chosen as a proof-of-concept was DICTAT-UPL, an impact model that can assess a satellite’s internal charging based on satellite material, energy spectrum, and duration of exposure. More information about SPENVIS’s DICTAT-UPL model can be found at the following link:

Below are 6 DICTAT-UPL model results, each simulating a satellite’s maximum E-field while exposed to an energy spectrum for a certain exposure duration. The two energy spectrums chosen represent an average energy spectrum that could be experienced by Geosynchronous (GEO) and Electric Orbit Raising (EOR) satellites respectively, while the exposure durations chosen were 24, 48, and 72 hours long. The results show that for all 6 spectrum-duration combinations, the simulated satellite (with default, fixed material) is not liable to experience breakdown (shown by the red line).

The CCMC would again like to thank the SPENVIS team for their support in producing these results.
