Re-run real.exe after changing namelist file
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... -
Modifying Seaice roughness length
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...- george_victor

How to add a new snow albedo schems in WRF/Noah-MP and add a new input varaibles in wrfinput ？
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...- Zilu Zhang

How to Implement Irrigation in WRF model?
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...- ahmedbably

Global Irrigation maps in Noah-MP?
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...- stormchasegenie

ICE Thickness/Accumulation - CANICE variable in the WRF
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... -

Cold bias due to fresh snow?
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...
