Land based output variables

Post by Howard » Wed Oct 15, 2014 2:30 am

I have been running a 4km grid nmm model ... and was interested in the land based data ... soil temp and soil moisture ... the initial output is a larger grid than the parent domain ... when you put a few time steps into the simulation you get nicer out put but ... the data about the coastline doesn't get to the coast line ... as expected ... and I am talking way more than the child grid of 4km in places 20km.h ... parent grid is 55km GFS.
Any ideas on how to improve output?

NMM nesting uses landmask from mother domain for all child domains. This is why you get very coarse coastlines and meteorological features around them.

Best solution is to switch to ARW core.
