Status of deliverables to the CCMC

• USU-GAIM3.1.1 (Global Assimilation of Ionospheric Measurements) has been installed at the CCMC, and the model accepts data from multiple sources:
  • GPS slant TEC
  • Electron density profiles from DISS ionosondes
  • DMSP SSIES in-situ electron densities
  • COSMIC TEC
• HI-IDED-DA (High Latitude Ionospheric Dynamics and ElectroDynamics with Data Assimilation) code has been installed at the CCMC, and the model uses data from multiple sources:
  • SuperDARN Radars for both hemispheres
  • SuperMag global distribution of magnetometers
  • DMSP cross track ion velocities and particle precipitation
  • AMPERE
• Runs on Request of the USU-GAIM3.1.1 will be available in 2018.
• Runs on Request of the HI-IDED-DA will be available in 2018.

The team has been in communication with the CCMC to help with model installation.
