UFS Medium-Range Weather (MRW) Practical Session Guide | Session 1: Set Up and Run the Model

This session will enable you to build and run a simulation with initial conditions from August 29, 2019, during Hurricane Dorian.  The simulation is configured for a C96 (~100km) resolution. The code base includes the UFS Weather Model, with pre- and post-processing, running in the Common Infrastructure for Modeling Earth (CIME) workflow. In order to perform the test, you will run the Medium-Range Weather Application for 48 hours.

In step 8, you will use the workflow software to make a change to the namelist that increases the concentration of cloud condensation nucleii (CCN), and perform another 48 hour run with this change. Then you will compare the total cloud cover field before and after the change.
