CCMC | The CCMC hosts a variety of models covering the entire domain from the solar corona to the Earth's upper atmosphere. CCMC works with model developers to make their models available to a wide research community through runs on request as well as instant runs. |

DREAM | The Dynamic Radiation Environment Assimilation Model (DREAM) is a Space Weather model developed at Los Alamos National Laboratory to understand and to predict hazards from the natural space environment and artificial radiation belts produced by high altitude nuclear explosions (HANE) such as Starfish. |

AE-8/AP-8 | CCMC Services available for AE-8/AP-8 RADBELT. A software package that includes (1) an improved and updated version of the old MODEL program (MODEL87), (2) an interactive driver program (RADBELT), (3) the electron AE-8 and proton AP-8 flux maps for solar maximum and minimum, and (4) the interpolation subroutines. RADBELT and MODEL87 compute omnidirectional, integral, or differential (in energy) fluxes of electrons and protons trapped in Earth's radiation for specified energy, L-value, and B/Bo range (B/Bo is magnetic field strength normalized to the equatorial value). The fluxes are obtained by an interpolation procedure from the AE-8 and AP-8 trapped particle flux maps. The RADBELT program allows the user to specify input parameters and options online and generates flux tables that can be stored for later use. |

SIZM | Inner Zone Model. A radiation belt proton, antiproton, and secondary model. |

Tsyganenko Geomagnetic Field Model and GEOPACK libraries |
The Tsyganenko models are semi-empirical best-fit representations for the magnetic field, based on a large number of satellite observations. The models include the contributions from major external magnetospheric sources: ring current, magnetotail current system, magnetopause currents, and large-scale system of field-aligned currents. The Tsyganenko model suite also includes GEOPACK library with 20 FORTRAN subroutines. Provides instantaneous calculation of external and internal geomagnetic fields along a field line and at a specified point based on T96 and Geopack08. |

Empirical Geomagnetic Field Models |
July 2017 Update: An optimized version of the TS07D model is now available. This update incorporates an upgraded version Bessel function evaluator, provided by Jay Albert, which significantly speeds up the model. We thank Jay Albert for these contributions. Also, the new model’s inputs and outputs are now double precision instead of single precision.

The magnetic vector potential is a useful quantity in computing the inductive electric field and is also used for computation of the third-invariant, however, is a computationally expensive quantity to evaluate. Similarly, in order to speed up computation time, the TS07D's modeled external magnetic vector potential field vectors have been precomputed on a uniform gridded cube. The same program as above will also work for these cubes as well. magnetic vector potential field cubes The Van Allen Probes' magnetic ephemeris (L*) from the TS07D model has been computed and the files are available here.

Empirical Models of Ionospheric Electrostatic Potential | Empirical models of ionospheric electrostatic potential combined with geomagnetic field models provide global maps of the electrostatic field across the inner magnetosphere for the analysis of storm-time convection and the buildup of the ring current and the radiation belt seed population. |

AF-GEOSPACE | A user-friendly graphics-intensive software program bringing together many of the space environment models, applications and visualization products developed by the Air Force Research Laboratory and others in the space weather community. |
