Hi I'm just learning WRF. I have a few questions, can anyone tell me?
I put both data as input data 2022-05-05_00:00:00 and 2022-05_06:00:00 to generate initial, boundary values with WPS and used it to run ./real.exe, ./wrf.exe.
(Run in a bidirectional nested model containing one input file, Domain 1 has a resolution of 1.5 km, Domain 2 has a resolution of 300 m, and Namelist_input has a &time_control of 10 minutes.) I attached the namelist.wps and namelist.input that I used.
As a result, wrfout_d01_2022-05_00:00 and wrfout_d02_2022-05_00:00 were generated. I have five questions here.
1. wrfout_d01_2022-05_00:00:00, wrfout_d02_2022-05_00:00:00 What exactly does this output data mean?
2. I set &time_control of namelist_input to 10 minutes, what does this value mean based on the output file?
3. I set the &time_control of the namelist_input to 10 minutes, but the less this value, the less accurate it is?
4. What is the difference between setting maxdom=1 in Namelist.wps, setting maxdom=2 in Namelist.input, setting maxdom=2 in Namelist.wps, and setting maxdom=2 in Namelist.input?
5. In the beginning, is it considered that the accuracy of the output value increases as the number of input data (GFS, FNL, etc.) that generate the boundary value is put in more?
Thank you.
