RADIATION DRIVER CRASHING

Postby kshama » Mon Jun 05, 2017 11:15 am

I have ingested two Landuse in the WRF model (one with 33 classes and other 40)
Both the landuse data that I have incorporated is having some effect on my wrf simulation.I tried Era Interim analysis data as well as GFS FNL data;in the both the cases the radiation driver crashes after the generation of the first hour file of each domain (4 in total).
How do I rectify this?
Without the radiation laws,the model is working fine but I want to incorporate the radiation physics in my simulation.
At first I thought it was happening due to my choice of meteorological data but now it seems otherwise.
THE ERROR IS :

Hi,

When there is a numerical instability (e.g. CFL error, or physically impossible values) then usually the radiation driver is the one which exits. Since you are making high resolution simulation, I would look into the issue from this point of view.

Hi,
I have the same problem but my run stopped after 45 days (the run is for 4 months). I have "similar" configuration in terms of resolution. When you say that it is a good idea to review the resolution you mean the temporal or the spatial resolution ? or both? - to start the review- .

Thanks
AngelaR
