NSF NCAR Mesoscale and Microscale Meteorology Laboratory invites you to attend the Joint MPAS and WRF Users Workshop from June 22 - 26, 2026. The event will be held in-person at the NSF NCAR Center Green campus in Boulder, Colorado, as well as virtually (online).

The primary objectives of the workshop are for developers and the scientific community to provide updates on the MPAS and WRF modeling systems, to discuss model development and issues, and to share progress in novel applications and evaluation. This year, we are especially seeking contributions on the following topics related to MPAS/WRF:

• Model development and updates, including improving model performance and efficiency;
• Data assimilation development and updates for global/regional applications, including assimilation of new observations;
• New or improved physics, physics infrastructure, and scheme evaluation;
• Applications that include coupling to other modeling components;
• Applications that enhance operational forecasting and seasonal prediction capability;
• Applications of AI/ML methods using MPAS/WRF.

In addition, this year we will host a series of short lectures on Monday afternoon and also offer mini tutorials on Friday related to (i) aerosol interactions/processes using MPAS-GOCART2G and (ii) mesh generation capabilities in MPAS. There will be discussion opportunities throughout the workshop on the topics of model development and infrastructures, and of the future transition of MMM development and active support of WRF to MPAS. More information will be provided on the workshop website at a later date.
