What's the meaning of GRDFLX value in water body?

Hi all, I am choosing the Unified Noah land-surface model in WRFv3.9.1, and have run a case. sf_surface_physics = 2, 2, 2, ( my choice) GRDFLX is the heat flux that goes into the ground. But I noticed that in water body(LU_INDEX=17 in IGBP-Modified MODIS 20-category Land Use Categories), GRDFLX also...

How to change water body completely in static data

Hi WRF forum, I changed all Water(17) to Croplands (12) and I have writed the new static data to the geogrid binary format. By the way, I choosed IGBP-Modified MODIS 20-category Land Use Categories. LANDMASK and LANDUSEF changed correspondingly. But the GREENFRAC didn't change correspondingly in geo...

Re: Wrong domains location in wrfout

I understand what you tried to do, but it's the wrong way. Your nesting should be like this: parent_id = 1, 1, 2, 3, parent_grid_ratio = 1, 3, 3, 3, Then check the position respect the parent domain. An useful tool to define your domain is GIS4WRF in QGIS, you start from the highest resolution doma...

Re: Wrong domains location in wrfout

@dengxw Are you trying to set up a case with multiple nesting domains? For example, D01 is the parent domain of D02, and D02 is the parent domain of D03, etc.? Yes, I am trying to set up a case with multiple nesting domains. I took cross85's advice and revised my namelist, but the position did not ...

Re: Wrong domains location in wrfout

The picture I sented before is XLAT in my wrfoutd01 showed by ncview. We can see different rectangulars of different domains. In general ,they should fit together so that we're just going to see one rectangle . I think it means the positions of the different domains do not correspond exactly. I am a...
