Re: Globcover in WRF-EMS

Hi Lucy,
How will WRF work with the globcover data since the spatial resolution is different.
For the moment, I try to find a trial version of Arcgis, since I do it by myself and not through an organization... :evil:

Re: snow parameter

Hi guys,
I also saw this problem, and came to the same conclusion : initialization with GFS field is too coarse. So I do the same. I substract the initial depth to the final depth obtained during the simulation....

Re: Nudging

You mean to input observation in WRF, instead for example GFS data ? No, I do not know but I wish I knew. I am especially interested in data from satellites. It is very important in winter, that means now... Snow cover data from GFS are too inaccurate because of the mesh size. So, when WRF is initia...

Re: Globcover in WRF-EMS

Hi, Are you sure that MODIS data are available for Europe? In the sfc option, you can use MODIS data but they are only available for US.... If I understand well your point, your are trying to use MODIS to replace USGS data when you define your domain. Am I right ? In this case this would be differen...
