radiation

In MPAS-A (v8.2.1) I have ran first simulation using rrtmg radiation scheme. After running this simulation I wanted to run the same simulation for CAM radiation. The even is in the same date just changing the radiation scheme. After executing the model we are facing the segmentation fault error...

Hi, I am running a simulation over 3 domains (9-,3-,1-km) to examine the role of cloud radiative feedback on coastal convection. Following other threads, I have included the following: 1) icloud = 0 2) cu_rad_feedback = .false.,.false.,.false. 3) shallowcu_forced_ra = .false.,.false.,.false...

I am curious about what air quality data (e.g., PM, O₃) are used when using the RRTMG scheme to obtain SWDNT, SWUPT, etc. I would also like to know in which directory of the WRF model these calculations are performed.

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?
