******** Overview ******** The `I-WRF weather simulation framework `_ from the `NSF National Center for Atmospheric Research (NCAR) `_ and the `Cornell Center for Advanced Computing `_ provides instructions for running the `Weather Research & Forecasting (WRF) `_ model and the `METplus `_ verification framework. This User's Guide includes several use case examples for running I-WRF using the `Docker `_ or `Apptainer `_ containerization software on NSF NCAR High Performance Computing (HPC) platforms, Cornell HPC, or on a user workstation.
