Using CFSRV2 data to force WRF

Hi All,

I am a newbie to using WRF. I have practiced real simulations using the gfs datasets available for the last 2-3 days. I want to use historical datasets like the cfsrv2 data set to force WRF. I was able to download the data, but when I ran: ./ungrib.exe, I get this error shown in the image below. I am unsure what the naming conventions of the cfsrv2 files should look like and if I have to make any changes to namelist.wps. I wonder why it doesn't see the data at the start time even though it exists.

The error message indicates that you have no CFSV2 data for the date of 2023-01-10_18:00:00.
Your namelist.wps shows that you need to process CFSV2 data for the period :

start_date = '2023-01-10_18:00:00','2023-06-18_00:00:00',

end_date = '2023-01-12_12:00:00','2023-06-18_12:00:00',

Please download CFSv2 data for this period and ty again.
Could you please direct me to the page where I can download the right cfsv2 files?. Apparently, it seems I downloaded the wrong ones. Thank you
