ARW core problem

Another problem I am facing with ARW core. I want to analyze the convective storm on ARW, but the problem is that when I do that, MSL pressure are too high comparing with input data. It is like 3-5 hPA higher than it should be. When I compile with NMM core everything looks good. I did numerious simu...

Re: Horizontal resolution

It seems that GRIB data files are 3 km. Possible that conversion did a bad job to the resolution... :(

Re: Horizontal resolution

well... I did convert .ctl file to .nc (with GRADS) to get a few variables and then imported to arcgis. Could convertion with Grads distort the resolution? By the way, these links to the screenshots of distance (which I posted earlier). The points defines the middle of the GRID not the corners or so...

Re: Horizontal resolution

Here you go: Dx and Dy = 27000. I guess these values you need &share wrf_core = 'ARW' max_dom = 3 start_date = '2010-08-07_00:00:00', '2010-08-07_00:00:00', '2010-08-07_00:00:00' end_date = '2010-08-09_00:00:00', '2010-08-07_00:00:00', '2010-08-07_00:00:00' interval_seconds = 21600 io_form_geogrid =...

Re: Horizontal resolution

I used Lambert Conformal projection (ARW core). What I understand that my grids real values goes along x-direction. 10. DX : A real value specifying the grid distance in the x-direction where the map scale factor is 1. But I am not sure where to find the values of longitude.. :/ Is there some kind o...

Re: Horizontal resolution

So no ideas? or is it just a unwritten rule where you should write in the scientific article "approximately 3 km resolution" ?

Horizontal resolution

Hello, I wanted to know what is real output data resolution. For example, if I am doing nesting up to 3 km grid spacing and then extracted data and then placed to arcgis, length between points are not 3 km. For Latitude http://imgur.com/sa6fEkw For Longitude http://imgur.com/sa6fEkw What is the real...
