    Some questions about SMOIS and CANWAT

    Hi WRF support, I am running a real-case simulation using the Noah Land Surface Scheme. I have some questions about the inconsistencies between my met_em, wrfinput, and wrfout files regarding a few land-state variables. The first one is CANWAT (canopy water). I was looking into my CANWAT...

    Stripes in U and V fields

    Hi WRF support, Recently, I noted there are some unphysical stripes (where the velocity of a particular component is some magnitude at one point while it is the magnitude but the opposite direction at the neighboring grid point) in my 3D U and V fields when viewing a wrfout file using NCVIEW...

    WRF 2D variables in NCVIEW

    Hi WRF support, I am curious why am I seeing some strange-looking boxes in some of the 2D fields (e.g., 2-m air temperature, 2-m potential temperature, 2-m water vapor mixing ratio, and heat fluxes) when viewing them using NCVIEW? I have attached the screenshot of T2 and TH2 plotted using...

    WRF fails with ExitCode 66

    Hi WRF Support, I am running a real-case WRF simulation (WRF v4.2.1) with four nested domains. My simulation initialized correctly with four wrfinput files, one for each domain, produced. However, when I executed wrf.exe, it failed pretty quickly while still writing the wrfout files at the...

    Questions about time step

    Hi WRF Help, I have a few questions about the WRF model time step. I am running a two-way nested real-case simulation with three domains. The coarsest domain has a spatial resolution of 9 km. I set my parent_grid_ratio to = 1, 3, 3, so my two nested domains have horizontal resolutions of 3...

    A question about parent_id in namelist.input

    Hi WRF help, I have a question about the 'parent_id' field in namelist.input file. I am running a two-way nested real-case simulation with three domains. In my namelist.input file, I have the parent_id of my coarsest domain set to 0 (as in many real-case examples). However, in some...

    linking WRF input files

    Hi, I am using NAM analysis to force my real-case WRF simulation. From the NCDC model archives (https://www.ncei.noaa.gov/data/north-american-mesoscale-model/access/historical/analysis/200706/20070622/), I downloaded all the .grb files for the day of interest. The NAM analysis files are named...

    QNSE PBL/SFCLAY simulated surface fields

    Hi, I am running a real-case simulation of a tornadic event in Manitoba, Canada. We performed our simulation with different PBL and surface layer schemes to see which scheme(s) would give us the best results based on convection timing/spatial distribution/structure, surface condition, and...

    WRF v4.1.2 Thompson Aerosol-Aware scheme QNWFA2D

    Hi, I am using the Thompson aerosol-aware MP scheme (MP option=28) in WRFv4.1.2 and WPS 4.1 for a real-case simulation over southcentral Canada. I have two domains in my simulation and I am using the 12-km NAM analysis as my meteorological forcing dataset. I downloaded the climatological...

    (SOLVED) WRF v4.1.2 compilation error

    I am trying to compile WRF v4.1.2 on Linux #1 SMP 3.10.0-1062.12.1.el7.x86_64. I am compiling em_real in WRF using Intel ifort/icc compiler with the dmpar option. My compilation failed when it ran into a problem with "wrf_io.o: In function `ext_ncd_open_for_read_begin_'", with a bunch of error...
