The CXD Combined Electron and Proton Flux Calculation

The Combined X-ray Dosimeter (CXD) is sensitive to protons with energies ranging from 10 to >100 MeV and electrons with energies ranging from 140 keV to >5.8 MeV. It is currently deployed on more than 20 satellites in the Global Positioning System constellation which are distributed across 6 orbital planes at medium Earth orbit (~20,200km). Data from the CXD energetic particle detectors has been publically released and provides a high temporal and spatial density dataset describing the near-Earth environment. These data have been previously cross-calibrated with both the NOAA Geostationary Operational Environmental Satellite and Van Allen Probes showing good agreement over a wide range of particle energy and flux. However, the current flux calculations treat the electron and proton channels independently despite cross-contamination between the two types of channels. A combined cross-calibration was performed to take advantage of this additional information and the new interpretation of the recorded data improves the overall flux calculations. This presentation will outline the results of this analysis and how this dataset can benefit the broader space weather community.
