    Model crashing at radiation time step

    Hi, Sorry for responding so late. There were issues with the HPC. Haven't been able to test much but tried running with v4.3.3 and it failed as well. Rsl attached. So I guess there's some issue with the input data but I have been able to run 8 other schemes with the same data. Will try further...

    Model crashing at radiation time step

    Hi, Is there any special static input data requirement with BouLac scheme? I have no problems running other schemes with the same data.

    Model crashing at radiation time step

    WRF-4.1.3 Model is crashing at radiation time step with BouLac PBL scheme, but runs successfully with other PBL schemes. Tried changing radt to other values but seeing similar crashing with similar error. Any help would be appreciated. &time_control run_days = 0...

    Difference between simulations

    Do the progn switch have any effect with chem_opt =201 as it does not include cloud droplet activation? chemics_init.F only give this: !!! TUCCELLA progn_sanity_check : SELECT CASE(config_flags%chem_opt) CASE (RADM2SORG_AQ, RADM2SORG_AQCHEM, RACMSORG_AQ, RACMSORG_AQCHEM_KPP...

    Difference between simulations

    Hi, please see the namelist. &time_control run_days = 0, run_hours = 00, run_minutes = 0, run_seconds = 0, start_year = 2018,2018,2018,2018, start_month...

    Difference between simulations

    Hi, I have observed big differences in all-sky surface and TOA radiative forcings between WRF only simulation and WRF-Chem simulation with aer_rad_feedback=0. Differences are close to 10-12 Wm-2. However clear sky radiative forcings are similar which implies difference in cloud simulation. What...

    Problem with hybrid vertical coordinate

    Hi, I am trying to run ndown.exe. I get errors: ERROR: The reference pressure is not monotonically decreasing I have tried with reducing etac value to as low as 0. But I still get the error. Is there any other option that I can try without possibly changing the domain? I have looked at...

    QCLOUD

    Hi, I just wanted to know if cumulus schemes contribute to QCLOUD, QRAIN variables or is it contributed only by microphysics scheme. Thanks.

    cloud droplet number estimation

    Hi, I wanted to know how is cloud droplet number (QNDROP) estimated with morrisson microphysics (mp_physics=10) in wrf-chem in case of both chem_opt= 201 and 202, as 201 does not support indirect effects and 202 does. For wrf-chem the droplet number is defined on basis of nc1d in...

    nc1d variable

    Hi, I wanted to know what does nc1d mean in module_mp_morr_two_moment.F. I am unable to relate the variable. The droplet number is defined on basis of nc1d. ! wrf-chem IF (flag_qndrop .AND. PRESENT( qndrop )) THEN qndrop(i,k,j) = nc1d(k) !jdf CSED3D(I,K,J) = CSED(K) END IF It would be of...

    WRF-Chem 4.3 crash

    Hi, Is there any update regarding the issue. Also wanted to let you know that I tried v4.3 real.exe to develop the input files which also did not work.

    WRF-Chem 4.3 crash

    Hi, I am having trouble with running WRF-Chem 4.3 as it crashes after few moments. I have successfully run simulation with v4.2.1 using the same input data and namelist. There are no cfl or chemistry related errors. I only get segmentation fault error. Kindly let me know how can I get this...

    AOD>0 with aerosol radiative feedback off

    So in both cases the AODs should be similar I suppose. Pardon my inexperience. I had calculated the difference in the AOD between the two scenarios (ON vs OFF) and found large differences exceeding 50-60%. Didn't expect such large differences.

    AOD>0 with aerosol radiative feedback off

    Hi Jordan, My aer_op_opt was 5 but had set aer_ra_feedback = 0. Should not the aerosols be invisible to radiation in that case? I had calculated AOD from TAUAER2 and TAUAER3, but EXTCOF55 is also non-zero. Thanks.

    AOD>0 with aerosol radiative feedback off

    Hi, Is it possible to have AOD values > 0 when aerosol radiative effects are turned off? I am getting such values, am perplexed. Appreciate any help. Thanks.
