    WRF output radiation at model levels ?

    Dear Ming, thanks for your answer! In the meantime I figured out the routine (RTRN) where I would like to output the variables TOTUFLUX and TOTDFLUX from. In the following list, I figured out the flow within the model: Do I need to pipe the variables through all the routines as...

    WRF output radiation at model levels ?

    Dear all, I would like to output radiation components (shortwave up, shortwave down, longwave up and longwave down) at model levels. How can I do that ? Many thanks for your help in advance! Klemens

    WRF with WSM5 as microphysics stops at first nested domain

    Checking Registry.EM_COMMON (WRF4.2.1) I found: state real CLDFRA ikj misc 1 - rh "CLDFRA" So cloud fraction don't need to be part of the wrfinput file. How to test now what's going wrong ?

    WRF with WSM5 as microphysics stops at first nested domain

    Since I work together with Pratiman on that case, I have to add that we have 5 other cases with the same set-up that have run succesfully. For none of these cases we have provided cloud fraction as input data. From this I would expect that cloud fraction is calculated within WRF and there might...

    WRF4.2.1 restart run crashes with "forrtl: severe (66): output statement overflows record, unit -5, file ...

    Further checking the internet boiled down the problem: https://github.com/wrf-model/WRF/issues/975 I could circumvent the problem by setting links from the directory where restart files are stored (defined by "rst_outname" from namelist.input) to the directory where WRF is run. You may find a...

    WRF4.2.1 restart run crashes with "forrtl: severe (66): output statement overflows record, unit -5, file ...

    Hi all, I try to make a restart run with WRF4.2.1.m, but directly after starting I it stops with the following error: alloc_space_field: domain 1 , 144503580 bytes allocated forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed...

    (SOLVED) Segmentation fault after CAM-CLWRF co2vmr

    Dear kwerner, sorry for my late reply/feedback, but I wanted to be sure that all my simulations finish successful: I did around 400 individual simulations (36 hours) with more than 50 not finishing successful, when I posted the first message. Most of them stopped at quite different simulation...

    (SOLVED) Segmentation fault after CAM-CLWRF co2vmr

    Dear kwerner, many thanks for your help. I uploaded the rsl.error files to the cloud. Filename is KB_rsl.error.tar Best regards, Klemens

    (SOLVED) Segmentation fault after CAM-CLWRF co2vmr

    Dear all, I try to run a simulation (WRF3.8.1) with input from ECHAM6. I did a lot of simulations for other days with a quite similar configuration, but this error appears for some runs/days: d04 2004-09-21_12:04:00 CAM-CLWRF co2vmr: 3.790000046137720E-004 n2ovmr: 3.190000086306100E-007...

    (RESOLVED) ERA5 var129 (geopotential) grib2 - how to ungrib ?

    Hi kwerner, Thanks for your request ! I figured out the problem. I should have read the WRF User guide more properly, as there is written: -> the metgrid Description was missing and so there was no output to the intermediate files. Best regards, Klemens

    (RESOLVED) ERA5 var129 (geopotential) grib2 - how to ungrib ?

    Dear all, I have downloaded ERA5 data in model levels (grib2) from CDS. Ungrib for all variables works fine except for var129, the geopotential. g2print.exe provides the following information (after transforming it with 'cdo sp2gp' from spectral to gaussian coordinates): ungrib - grib...

    (RESOLVED) ERA5 from CDS - g2print does not properly read timesteps ?

    Ok, I found the problem also described in this great blog http://www.iup.uni-bremen.de/~hilboll/blog/2017/11/using-ecmwf-ifs-cy43r1-with-wrf/ under Preparing IFS Grib files for ungrib.exe Here it is recommended to split the file with CDO in one file per timestep. Klemens

    (RESOLVED) ERA5 from CDS - g2print does not properly read timesteps ?

    I have read this topic and had contact with Andrea. In her case the problem was due to the definition of the region in the download script. The only other information potentially related to my problem from this thread is the violation of the grib1 standards but since I am expecting grib2 data...

    (RESOLVED) ERA5 from CDS - g2print does not properly read timesteps ?

    Dear all, I try to run WRF with ERA5 data on model levels downloaded from CDS. The download script for one variable is below: c.retrieve("reanalysis-era5-complete", { "class": "ea", "expver": "1", "stream": "oper", "type": "an", "param" : parameter_str+".128", "levtype"...
