high resolution data for geogrid input?

[willrudisill]

Hello WRF-Hydro community, 

I would like to run the NoahMP lsm at a spatial resolution of 250-500m for one medium sized watershed. To do so I'll be using WRF-Hydro version 5.1

I have WRF/WPS v.4.1 (?) compiled and working so I can create geo_em* files...

However the only WPS static data that I have or can find is the 30 arcsec which is around 1km (found here https://www2.mmm.ucar.edu/wrf/users/download/get_sources_wps_geog.html)

I can't find a similar question after searching. Are there any up to date tutorials/workflows out there for using higher resolution topographic data for geogrid? 

Thanks

I frequently generate WPS tiles using high-resolution gridded data. By far the easiest way to accomplish this is using the GIS4WRF plugin for QGIS. You can bring in any raster dataset and use the GIS4WRF plugin to generate WPS tiles from a layer in your project. This utility will create all the tiles you need as well as the index file for WPS. You may need to edit some of the metadata in the index file, but I have found it to work well.

If you want to create WPS tiles manually, you can create a single-tile WPS binary dataset using gdal_translate.exe. Look at the WPS user guide, section titled "Creating an Urban Fraction Field from NLCD Data" here:

    www2.mmm.ucar.edu/wrf/users/docs/user_guide_V3/user_guide_V3.9/users_guide_chap3.html

If your grid is too large (>99,999 x 99,999), you may need to resample the data before building the WPS tiles.

Here are some other resources:

Good luck,

Kevin

Awesome, thanks for the suggestions! Hopefully it goes smoothly
