Updating boundaries at different time interval for diffrent variables

[Dipti Hingmire]

Hi All,

I want to downscale CMIP6 climate projections using WRF. Most of the climate models provide very few variables at 6 hourly interval e.g. upper air temperature and winds. Some of the required variables by WRF are available at lower frquency (daily) e.g. soil moisture. Is it possible to update boundaries at different time interval for diffrent variables? If yes, can you please tell me the steps to do that.

Thanks,
Dipti

I got answer to my question from following thread - Running WRF with CESM2 data
Only difference is, I need not copy the surface value at 6hourly interval, only following steps worked for me (answer by Ming)-
Please try the following steps:
(1) ungrib daily data and name them as SFC:yyyy-hh-dd_hh by setting
&ungrib
out_format = 'WPS',
prefix = 'SFC',
(2) ungrib upper level data and name them as UPA:yyy-hh-dd_hh by
&ungrib
out_format = 'WPS',
prefix = 'UPA',
(3) in your namelist.wps, set fg_name = "SFC", "UPA"
(4) run metgrid.exe.
