HI Fatemeh,

     I can help you with generating the HRLDAS forcing files using NLDAS inputs but I am not not sure what you meant by the main configuration file. Are you referring to the two namelist files, namelist.hrldas and hydro.namelist, or the NCL script that is used to regrid and downscale the NLDAS data and create the HRLDAS forcing files?

Thanks,
Yongxin

Dear WRF-Hydro Team,
 
I am currently working on regenerating HRLDAS forcing data using NLDAS
inputs for the Croton test case in WRF-Hydro Model. My main goal is to gain
hands-on experience and better understand the process of generating HRLDAS
forcing inputs.
 
To proceed effectively, I was wondering if anyone could kindly share the
main configuration file that was used in the Croton test case. Access to
this config would be extremely helpful in learning the correct workflow and
structure.
 
Thank you,
Fatemeh

Dear Yongxin,

Thank you so much for your response.

I would like to start from scratch and follow your approach. Could you please guide me through the correct procedure for generating the HRLDAS forcing files using NLDAS inputs?

I really appreciate your help.

Best regards,
Fatemeh Shirkhanloo

Hi Fatime and Yongxin,

I'd also be curious if anyone has the time to share some guidance on how to regrid the meteorological forcing inputs from NLDAS grib or netcdf files. I'm also working through the Croton example case, and I've been able to run the WRF-Hydro tutorial with the pre-prepared forcing inputs and use the Python GIS pre-processing toolbox to make the "routing stack" input files, but I've had more trouble preparing forcing inputs from scratch from NLDAS netcdf files. I wasn't able to find the forcing engine configuration file "nldas_fe.config" referenced in the tutorial, so I've been trying to adapt one of the template configuration files from here, but it involves choosing a lot of parameters, and I haven't found much documentation explaining how to do this. I'd appreciate if anyone more experienced with WRF-Hydro could share advice for finding documentation/guidance on regridding!

Thank you,
Caroline Hashimoto
