Hello everyone, I am trying to run WRF with Initial and lateral boundary conditions which are derived from WACCM(National Center for Atmospheric Research Whole Atmosphere Community Climate Model) . The model top of WACCM is about 5.9 × 10-6 hPa (∼145 km). When I use WPS to generate the...

I am trying to execute ungrib.exec and I am getting below error *** Starting program ungrib.exe *** Start_date = 2022-09-12_00:00:00 , End_date = 2022-09-12_06:00:00 output format is WPS Path to intermediate files is ./ ERROR: Grib2 file or date problem, stopping in edition_num. I am...

Hello WRF Community, I am trying to use SRTM_3s topography data from the Cheyenne WPS_GEOG directory for my 259m (do4) and 86.3m (do5) resolution simulation run. I have done the following necessary steps to execute this: 1. Edit GEOGRID.TBL file by setting lines to HGT_M...

Hello to all. I am in the process of attempting to ungrib ERA-5 Reanalysis 0.25-degree data available from the UCAR Research Data Archive for simulating Hurricane Ivan. I am used to routinely having to reobtain ERA-5 data and model outputs as the supercomputer I perform tasks on purges the data...

Hi All, I'm attempting to run geogrid using precompiled WRFV4.4 and WPSV4.4 on Cheyenne and keep receiving a time out error after URB_Param begins to process: Processing URB_PARAM MPT: Launcher network accept (MPI_LAUNCH_TIMEOUT) timed out MPT: Launcher on r7i7n7 failed to receive...

Hello, I downloaded USGS 1/3" topographic data for some simulations I am working on. I was able to stitch together multiple tiles into my own dataset according to WRF guidelines (i.e. the whole 0xxxx-0xxxx.0yyyy-0yyyy naming conventions), and can successfully run geogrid.exe and generate maps...

THE BELOW POST HAS BEEN RESOLVED THE PROBLEM WAS THAT "GEOG_DATA_RES" needed to be defined for both domains. Hi, I am attempting to create a nested domain configuration such that the child domain has the same resolution as the parent domain. The reason for wanting to do this is that I have...

Dear altruists, Can anyone share any detailed documents or ideas in preparing Vtable for any datasets (i.e. ECMWF 10-days new open datasets)? I don't know how to set the values for GRIB2 Discp, GRIB2 Level, Level Code inside Vtable. I got some values from g2print.exe. But I think, it shows some...

Dear Colleague, I would like to know which model is handled by WRF, Digital Surface Model or Digital Terrain Model (specifically Digital Elevation Model)? Best wishes, Stella

Dear WRF Community, I have a question on substitution of ALB/LAI in WRF V3.9 : The amounts of LAI and ALBEDO in WRF output and that in WPS output are different, although I set sst_update=1 , usemonalb=true,rdlai2d = true and auxinput4_inname = 'wrflowinp_d<domain>' in namelist.input. . Thanks...
