Grads problem with tmp2m

Post by Tintin87 » Thu Jun 30, 2011 11:55 am

Hello,
I have some problems with WRF particularly with Tmp2m, Tmax2m and Tmin2m.
I run WRF-NMM, and when I try to create map with TMP2m, I have only the first and second time of TMP2m, TMAX2m and TMIN2m.
You can see this at http://meteo.mezieres.free.fr/WRF-NMM35.php?p=tmp2m&t=0
The others parameters are good.
My CTL file is

Code: Select all

dset ^201106300000_nmm_wrfout_d01.grb2

and the line for TMP2m is

Code: Select all

TMP2m   0,103,2   0,0,0 ** 2 m above ground Temperature [K]
My physic model is
Cumulus Scheme : Grell-Devenyi Ensemble
Microphysics Scheme : Ferrier Microphysics
PBL Scheme : Global Forecast System (GFS)
Land Surface Scheme : Noah 4-Layer LSM
Number Soil Layers : 4
Surface Layer Physics : NCEP Global Forecast System
Long Wave Radiation : GFDL Long Wave Radiation
Short Wave Radiation : GFDL Short Wave Radiation

Has someone encountered this problem ?

This scheme does not support 2m fields. If you want them you will need to use MYJ scheme for PBL.

Hello all,

I have recently contacted Robert about this problem.

2m temperatures are not calculated directly by the GFS scheme or scheme other than MYJ, but normally wrfpost should extrapolate these parameters .
Its is a bug in 3.2 beta, and it will be hopefully corrected in a future release.
