CAFE Update

September 2026

Starting on September 28, 2026, the CAFE - Neutral Density Equivalent Proxy (NDEP) drivers are integrated into the CCMC Runs-on-Request (RoR) system for MSIS 2.1 runs.

CAFE, Calibration Atmosphere with Forcing Estimates, provides data-assimilative effective solar and geomagnetic drivers estimated from satellite-drag observations. These drivers are designed to improve MSIS neutral-density calculations for satellite-drag applications.

How to Use: Users can select the CAFE driver option under Model Version in the CCMC MSIS ROR interface

Acknowledgement: The CCMC extends its gratitude to Dr. Marcin Pilinski and collaborators for their support in making this capability available to the community.
