Session 4 : WRF System Setup: Directories, Static Data & Domain Config

Welcome to this recap session of the fourth class! In this video, we review the file structure and prerequisites needed for our next WRF modelling class. We cover the organisation of the NWP and Build_WRF directories and demonstrate how to acquire and visualize Global Forecast System (GFS) data. Additionally, we walk through the process of configuring a simulation domain using the WRF Domain Wizard, using Switzerland as a case study to understand map projections and grid resolutions. Key Topics Covered: Directory Structure: Organizing WRF, WPS, and Data folders. Data Management: Downloading GFS Initial Conditions using curl and understanding GRIB2 vs. NetCDF formats. Visualization: Using GrADS (sdfopen) and ncview to inspect meteorological variables like Relative Humidity and Vertical Velocity. WRF Domain Wizard: Setting up a new domain, selecting projections (Lambert Conformal), and defining grid resolution. Static Data: Understanding the role of WPS_GEOG (topography, land use) files.
