radiation

Hello, I’m currently running WRF with the Thompson aerosol-aware microphysics scheme (mp_physics=28) and using the aerosol climatology file QNWFA_QNIFA_SIGMA_MONTHLY.dat to provide nwfa and nifa. In my namelist, I’ve set aer_opt=3, which I understand corresponds to G. Thompson’s...

Hello, I am using WRF-4. 5 and want to see some radiation variables output over my domain. I got the variables like ASWUPT for normal and ASWUPTC for clear sky in wrf output file. Similarly I saw other variables of radiation too. But when I plot them there is no difference in normal and clear...

Hi! I'm using WPS4.5 and WRF-Solar 4.5. I set aer_opt = 2, aer_aod550_opt = 1, aer_aod550_val = 0.12 in the namelist.input and run wrf.exe. I found that AOD5502D in all wrfout files is also 0.12. I have several questions: (1) It seems that the value of AOD did not change at all during the...

Dear WRF Community, I am currently using WRF-Chem to simulate dust events. I would like to observe the impact of turning on and off dust radiation feedback on the analysis results while retaining dust emissions. However, I am unsure how to turn off sand and dust radiation feedback. I hope to...

My WRF-4.6 Model is crashing at the radiation time step with both tropical and CONUS suites and for all other configurations. I tried changing radt to other values but saw similar crashing with a similar error. Any help would be appreciated.

Hi, all How do I set up a constant radiative cooling when I want to run a WRF experiment? This experiment is not the ideal case that comes with WRF, but the initial field data made by myself. Should I adjust the parameters in the WRF mode and then recompile? Or modify it directly in the...

I am calculating downward short wave flux using WRF. I found a variable called SWDOWN among the output variables, and I am curious whether this variable is instantaneous or averaged according to history_interval. I would like to know whether the value of SWDOWN is the instantaneous value of...

Dear all, I have been stacked on this problem for half a year, I am gateful that if someone could help me solve this problem. My situation is that the WRF-Chem V3.9.1.1 is always stopped after photolysis driver (rsl.error.000?) and it also happens in latest version (WRF-Chem V4.5.1). The stop...

Dear all, I used the Goddard scheme for SW Radiation and the RRTMG scheme for LW Radiation while running WRF-Chem using RADM2-MADE/SORGAM chemistry options. I want to calculate the net SW radiative flux in the atmosphere using this formula:ΔFatm = ΔFTOA - ΔFsurf However, I noticed that only the...

I want to set the solar radiation from convective cloud tops to a fixed value (such as 800w). But I didn't know how to set parameters. whether can I set the constant value through modifying the namelist.input. thank you！

I want to study the effect of black carbon aerosol radiation feedback on O3, so I want to design an experiment to only turn off its radiation feedback. It seems that this cannot be done just by modifying namelist. What should I do?
