    swint_opt = 2 is diagnostic variable?

    you need to set up couple_farms to true in the namelist for the GHI from FARMS to be used in the surface energy balance. Otherwise FARMS outputs are only diagnostic variables. Pedro.

    WRF solar EPS

    Your last sentence is the way to do it: If you want 10 ensemble members you need to run WRF-Solar EPS 10 times with different nens values Pedro.

    How to get the solar position variables used by WRF-Solar

    To add variables to the WRF output you need to add the letter h to the proper column in the entry of the variable in the registry.

    WRF - Solar

    You need to modify the Registry.EM_COMMON file in Registry. You need to find the line that defines the variables you would like to have in the wrf output and and add the letter h in the proper column (see the SWDOWN2 entry). After this change, you will have to recompile WRF.

    WRF-Solar:2) variable read via auxiliary file(s) in WRF I/O API-conforming netCDF format. How do I make this netCDF file?

    You have to identify the aerosol data you would like to impose in the WRF-Solar simulations first. These are the variables you can impose (from the registry): state real aod5502d ij misc 1 - i{15}r "AOD5502D" "Total aerosol optical depth at 550 nm" "" state...

    MAD-WRF: Setup of passive and active modes

    Hello, Your configuration looks correct. It is as described in the WRF/doc/README.madwrf file with the MAD-WRF documentation. You can try compiling WRF in debugging mode (compile -d or compile -D) to obtain more information about the segmentation fault. If you are ingesting observations to...

    CLD3 - already available in WRF Solar EPS?

    yes, you can. These are the options related to that scheme: pert_cld3 = .false. ! Activates perturbations to clouds generated with icloud = 3 pert_cld3_qv = 0.0 pert_cld3_t = 0.0 so you can set pert_cld3 = .true. and pert_cld3_qv and pert_cld3_t = 1.0 Remember...

    Run WRF-solar

    You need the AOD at 550 nm. You can impose it to the WRF-Solar simulation to account for the aerosol direct effect by setting aer_opt = 2 in the physics block of the WRF namelist. Please take a look at the documentation in the user guide part of the WRF-Solar website...

    Obtain average irradiance values in each model output

    The code to accumulate the GHI is now in the latest version of WRF (v4.4). We have no plans at this moment to add other irradiances, but it should not be difficult to extend the code using the GHI case as an example.

    Problem With WRF-Solar Output SWDDNI and SWDDIF.

    Please edit the Registry/Registry.EM_COMMON file and replace this line state real swddni ij misc 1 - rd "SWDDNI" "Shortwave surface downward direct normal irradiance" "W m-2" "" with this one state real swddni ij misc 1 -...

    Deng Shallow convection

    It is not clear if it should be turned on or off. You can take a look at this article that points to positive impacts of activating the parameterization at 3 km grid spacing:

    MADWRF and aerosols

    Hello, To use climatological aerosols in the MAD-WRF passive mode (mp = 96) set up aer_opt = 1 together with ra_sw_physics = 4 (RRTMG). No need to use the use_aero_icbc option. Pedro.

    WRF v.3.81+ diffuse radiation question-- source code

    I believe this is the reference you are looking for: Ruiz-Arias, J. A., H. Alsamanra, J. Tovar-Pescador, and D. Pozo-Vázquez, 2010: Proposal of a regressive model for the hourly diffuse solar radiation under all sky conditions. Energy Convers. Manage., 51, 881–893...

    solar_diagnostics output variables not showing in WRFout

    GHI should be in the output. It is a variable called SWDOWN. The direct normal irradiance (DNI) and the diffuse irradiance are exposed via the Registry. You need to edit the file Registry.EM_COMMON and add the variables SWDDNI and SWDDIF to the WRF output by adding a h in the IO part of the...

    mad-wrf run

    I think several cloud server providers have the data available in real time.

    mad-wrf run

    Hello, MAD-WRF is included in the WRF release. In the WRF/doc directory there is a file called README.madwrf with information on how to run MAD-WRF. The variables that you mention are usually calculated with satellite retrievals or ground observations. You will have to put the observations in...

    Adding GOES-R

    Marcelo, You have to write the GOES-R data in the WPS intermediate file format. You can take a look to this link: If you click on the "WPS format" hyperlink you will be able to get a sample file with code (Fortran) to write...

    Strange patterns in WRf-solar irradiance variables

    The model is generating broken clouds. If you have a satellite image available for this day you can check if there were broken clouds this day.

    Strange patterns in WRf-solar irradiance variables

    Those patterns appear to be the effects of clouds. You can take a look at the variables from the solar diagnostic package that characterize the integrated hydrometeor content. Take a look to the README.tslist file in the run directory for a description of the available variables.

    Run with different microphysics

    for mp 8 you can set aer_opt = 1 but for mp 28 you can use aer_opt =3. Other microphysics should be compatible with aer_opt = 1. The largest differences should come from the microphysics. The diffuse should be zero during nighttime.
