The Mesoscale and Microscale Meteorology Laboratory of NCAR invites you to attend the Joint MPAS and WRF Users' Workshop from June 3 - 6, 2025. The event will be held in-person at the NCAR|UCAR 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.

1. Model development and updates, including improving model performance and efficiency
2. Data assimilation development and updates for global/regional applications, including assimilation of new observations
3. Model comparisons between MPAS and WRF
4. New or improved physics, physics infrastructure, and evaluation
5. Applications that include coupling to other modeling components and/or enhance operational forecasting capability
6. Applications of AI/ML methods using MPAS/WRF to improve weather prediction

***The deadline to submit an abstract has passed. Workshop program will be available in mid-May.***

In addition, we will offer short tutorials on Friday related to new developments, and there will be discussion opportunities throughout the workshop on the topics of model development and infrastructures, especially as they relate to the implementation of MPAS in the Unified Forecast System (UFS). More information will be provided at a later date.
