I got the error from rsl.out after running the wrf.exe in the following picture. The namelist.input and rsl.out was attached. I have already tried to change the physical scheme (e.g., PBL scheme, microphysics scheme, or radiation scheme) (emitted longwave <0; skin T may be wrong due to...

Hi, I have completed a 4-nested simulation with resolutions of 12150-4050-1350-450m using WRF 4.0, and used ndown to make the driving file for 150m. However, when continuing the 2-nested simulation with 150m and 50m resolutions, I encountered "Segmentation fault" in module_sf_sfclay. This error...

Model Code WRF 4.5.2 Noah-MP v4.5 Platform Linux x86_64 INTEL (ftn/icc): Cray XC (dmpar) Model Summary 4km SE USA Restart run starting from Oct. 1974 through Dec. 2020 Forced with ERA5 from the Copernicus CDS via python API Geogrid run with GEOGRID.TBL.ARW.noahmp Notable modules: Thompson MP...

Hi, This seems like a very basic question, but is it necessary to modify MPTABLE for Noah MP to run WRF in the southern hemisphere (or anywhere outside of the US)? The LAI values, for example, seem to be set monthly but presumably these would be different depending on hemisphere. I assume this...

Hello, I'm running a model with WRF version 4.5.2, but it can't proceed any further due to an error. What is unusual is that if I set the domain to nesting d02, it runs normally, but if I set it to d01, the model does not run. Also, even when set to one domain, it performs well if I change...

Hi all, When running the WRF scheme, I found that variables related to LAI, including TGV, TAH, TZV, etc., had abnormal values. After investigation, I determined that these areas had a land use type of 15 in MODIS, which corresponds to snow and ice. By checking the source code, I discovered...

Hello everyone, I am currently using WRF_NoahMP to conduct irrigation experiments. Since my case is not in the United States, I need to prepare the crop data myself. My process is as follows: 1. I have 1km planting data for three types of crops, using this data to calculate the crop fraction in...

Hello everyone! I'm trying to validate outputs from temperature and water content of soil layers of WRF, using NOAH-MP as land surface model. But I am not sure what these variables represent. NOAH-MP discretizes the soil into 4 layers, so does the temperature and water content of each layer...

We use WRF version 4.5.2 for urban climate studies. Registory.EM_COMMON has been modified to output variables related to urban areas. Some skin temperature results, such as TR_URB2D (urban roof skin temperature), TB_URB2D (urban wall skin temperature), and TG_URB2D (urban road skin...

Dear Community, I have ran a same simulation successfully. When I modified the land cover data slightly (mainly Urban parameters for urban canopy model) and rerun the same simulation, it crashed after almost one month of simulation and shows as follows: ERRENG = 1.368042 at i,j...

Dear all, I am confused about how to calculate the total soil moisture when considering multiple layers. The stimulated soil moisture has four layers (i.e., 0-10cm; 10-40cm; 40-100cm; 100-200cm) in Noah-MP module. But if we want to get the soil moisture in the layer 0-40cm and 40-200cm, can we...

I am currently studying the heat island of Bangkok, Thailand as part of a Southeast Asian urban climate research. This study uses WRF versions 4.2.2 and 4.3.3. Also, Noah LSM and Single layer UCM are used. I have run simulations on many cases, but the simulations do not reproduce the daytime...

Hi I'm doing some tests with noah-mp options on the namelist file: &noah_mp . .. ... / Should I run real.exe for each modification on the namelits's noah_mp parameters? For example, to modify &noah_mp ... dveg = 4 ... \ for &noah_mp ... dveg = 9 ... \ I'm not sure, but running...

Hi! I'm planning a sensitivity test. I've already made a control simulation, now I need to make a simulation with modified roughness length. I understand that usually the roughness length for seaice is set a constant, and it is straight forward to modify it into a new constant value. However, in...

Hi all, I am trying to fully coupled SNICAR snow albedo shemes in WRF/Noah-MP(online). The SNICAR has been Coupled in WRF/CLM already and I am planning to ake out the SNICAR fortran subroutine from CLM model code and create a new physics option in Noah-MP. Now I have the problem that the SNICAR...

Hi everyone! I'm currently working on a research to study how irrigation can influence some climate parameters in Egypt. I've already conducted a control, basic run using WRF v4.1.3. Now, I would like to introduce irrigation into the model. What my mentor is saying we could modify the Noah...

Greetings, I am trying to use the Noah-MP irrigation routines which require information generated in geogrid. This works fine for U.S.-specific domains. However, I have a grid that extends from upstream of Hawaii and downstream through Western Africa. Hence, geogrid crashes presumably because...

Hi, I was actually facing difficulty in figuring out whether the CANICE(mm) output in WRF is incremental or cumulative(total ice accumulated from start till that particular time instant)? The reason why I am asking is because I ran a simulations for an ice storms and then after observing the...

I am running 24hr forecasts initialized from GFS with NoahMP. Over areas of snow there is a very strong cold bias. I suspect this is because when the model is started it considers this snow to be new snow, even though it has been there for many months. Is that possible? Is there a way to fix or...
