Thanks for the reply! It helps me a lot.

Hi, kwerner! I thought the above results from the wrfout data were not correct and I'm interested in how to get the proper distribution of cloud fraction from wrfout outputs. I'm not working on the improvement of cloud simulation in WRF. Maybe the result from the ERA5 is not real and I just...

Hello, everyone! I tried to get cloud fraction over regions with different elevations (e.g. the Tibetan Plateau, the Sichuan Basin). The low, middle and high clouds can be obtained by the funtion of "wrf_user_getvar(cfrac)" in NCL. The default criterion of low, middle and high clouds is height...

Thank you ! Attached are the configure.wrf and log.compile. The warning may be related to the inconsistency of the history_interval (1h) and the interval of wrfbdy and wrflowinp (6h) files. But I have no ideas of the error messages. May be it is related to the deleted files of...

Hi, everyone! I conducted a one-month simulation from 2020052000-2020070100 using WRF-V4.2. The first 10 days were regarded as spin up time. The WPS and real procedure were done before running the WRF. I set the resart interval of 4 days. The nearest restart time was 2020-06-01_00:00:00.The wrf...

Thank you for your reply and it helps me a lot!!

Hi, everyone! I intend to conduct one-month WRF simulation to indicate the sensitivity of the percipitation to a revised radiation parameterization. I have three issues about the input data and spin up time. 1. ECMWF or FNL? Previous studies showd that the ECMWF reanalysis (0.25*0.25;0.75*0.75)...

Hi, kwerner Thank you for your generous help!! I have solved this issue by modifying the configure.wrf and configure.wps. and recompiling both the WRF-V4.2 and WPS-V4.2. I guess the main problem was that I didn't modify the following two settings as it tells in the configure.wrf. --------from...

Hi, everyone! I have installed WRF-V4.2 successfully using ifort/icc compiler with the selection of 16, dm+sm But I encountered errors when compiling the WPS-V4.2 with the selection of 19, ifort/icc compiler, dm. The ungrib.exe was successfully built, but the other two failed. I supposed the...

Thank you~ Happy New Year!!

Hello, kwerner : Sorry for the delay! I have made the following changes and it works now! 1.dimension "c"->"z" 2.the new dimension in module_wps_io_arw.F is "2" I use the version of WRF-4.2.

Hello I have encountered prolems in the compile procedure when adding external array with new dimension to the Registry file and other physical modules. Here are the screenshots of the modifications I have made in the registry.dimspec and Registry.EM_COMMON and errors. I will appreciate with...

Thank you!

Hello, Ming! Thank you for the detailed instructions! I have interpolated the external array onto the model grid accroding to the namelist.wps (the same e_we,e_sn and the same projection) in advance in grd format and I wondered that whether I need to conduct the first step 'write the data in the...

Hello! Have you solved this problem? I have similar problem with you.

Hello, everyone! I am working on calibrating some radiation-related variables in WRF. I need to read in several external arrays (.grd) in WRF and I have interpolated these arrays onto the model grid dimension accroding to the setteings of the namelist.wps. How to read in them and write them...

Hello, Ming Sorry for the delay of the response. I have solved this problem by changing the initial and lateral boundary field which can be downloaed at https://rda.ucar.edu/datasets/ds084.1/#!description. I searched the keyword of error files in the forum and found one topic with nearly the...

Hello,Ming Sorry for the delay of response! I searched for the keyword of error in this forum, and found one having nearly the same problem with similar namelist.input...

Hi, Ming These are some diagnostic-related option. Since this namelist.input is given by my senior, I'm not very familiar with the explicit meanings. I used 120 pocessors to run the wrf task, and I tried to add to 140, but it still failed. Thank you for your help!!

Dear Ming, I have checked the log files that I was using the original WRF-4.2 and WPS-4.2. Attached are the log files and one of the input data.The time interval is 3h. 120 executive hosts may be enough? Thank you for your help!
