[Wrf-users] RFP: High resolution wrf simulation

hello,Volker,

I don't think wrf will meet your mission:
1, wrf uses sigma cooradinate, which means produce data for a given height for entire field is imporsible/hard.(ps. posible for a fixed position at given time)
2,as u messioned, you need wind at 100m,120m etc.,that means your wrf simulation's vertical should be about 20m at least, though wrf can be set up with a high vertical resolution, i still think maybe it's not a good idea. And,high vertical resolution without correspoding high horizonal reso. is meaningless ,which still is a problem now.
sorry I don't know what is WRG you mensioned.

btw,near surface wind speed produced by wrf may has a signifcant bias, esp. in complex topograpgy like moutain area.
maybe u should have a look at CALMET, or something like it.

goodluck.

>Dear WRF users,
>we are currently looking for an experienced individual or company who would run WRF for an area (hi-res nest) of about 100 km x 100 km in France, with a horizontal resolution of about 100m, for a period of one year.
>The terrain in the region is simple, with elevations of up to 300 m. As the output of the simulation, we are interested in raster maps (e.g. GeoTIFF) with average wind speed and (ideally) WRG files for 80 m, 100 m and 120 m height above ground.
>Boundary conditions could come from either MERRA or ERA reanalysis data. Results should be prepared within two months.
