Update land use category resolution #12

Closed lewisjared closed 3 weeks ago

lewisjared commented 1 month ago

The problem

The 10km grid uses usgs_10m for its land use categories when 30s fields are available (usgs_30s). 10m resolution is ~300km resolution, but 30s is about 1km according to some random website I found.

@prayner Is there any reason not to use the higher resolution product?

prayner commented 1 month ago

In fact 10m is 1/6 degree or about 15km but the point still stands. We should certainly use the high-res when available. I'd need to look back at earlier versions of the setup scripts but they did use the 30s data at some stage.

Opps my googling skills didn't work apparently.

prayner commented 1 month ago

correction from last comment, they still do use the 30s res but only for domain 2 & higher. The namelist.wps reflected cases where domain 1 had a much coarser resolution. I'll test changing this and if it works we then ... what ... open a PR?

prayner commented 3 weeks ago

This tests out fine once I remember to remove the old geo_em file. The only change is a setting in namelist.wps. Should I open a PR then close the issue once it's merged?

lewisjared commented 3 weeks ago

Yes. That would be great thanks

prayner commented 3 weeks ago

change is already implemented in namelist.wps so will close
