…uerto Rico domains. Includes new code and configuration files. Tested on WCOSS2.

This is still the code that was inital submitted for 3.1. I think the retroactive 3.0 update erased parts of this somehow. core/forcingInputMod had the 3.0 setup and 3.1 config files were missing

Pull request overview

This PR adds support for RRFS (Rapid Refresh Forecast System) forcing data for three regional domains: North America (NA), Puerto Rico (PR), and Hawaii (HI). The changes introduce new input forcing options (keys 24-26), corresponding regridding functions, and configuration templates for each region.

Adds three new RRFS regional forcing options with domain-specific configurations
Implements time-handling and regridding functions for RRFS NA, PR, and HI domains
Updates forcing input module to support new GRIB variables and output mappings
Provides configuration templates for operational use on WCOSS systems

+def find_rrfs_na_neighbors(input_forcings, config_options, d_current, mpi_config):

+    Function to calculate the previous and after HRRR conus cycles based on the current timestep.


The docstring incorrectly refers to 'HRRR conus cycles' when this function is for RRFS NA. Update to 'RRFS NA cycles'.

Suggested change

The status message refers to 'Conus HRRR Data' but this function processes RRFS NA data. Update to 'Processing RRFS NA Data'.

Suggested change

Comment references 'HRRR forecast cycle' but should reference 'RRFS forecast cycle' for consistency with the function's purpose.

+    dt_tmp = next_hrrr_date - current_rrfs_cycle


Variable name 'next_hrrr_date' is inconsistent - should be 'next_rrfs_date' to match the RRFS context and the variable defined at line 764.

Suggested change

dt_tmp = next_hrrr_date - current_rrfs_cycle

dt_tmp = next_rrfs_date - current_rrfs_cycle

Temporary file name uses 'NAM_NEST_TMP' prefix but this function handles RRFS HI data. Update to 'RRFS_HI_TMP' for consistency.

Suggested change

input_forcings.tmpFile = config_options.scratch_dir + "/" + "NAM_NEST_TMP-{}.nc".format(mkfilename())

Inconsistent array formatting compared to similar entries (24-26). Line 391 ends with a closing bracket and comma while lines 395, 399, and 403 continue the array definition. This entry (23) should follow the same pattern as 24-26.

Comment ordering is inconsistent - line 48 shows '25 - RRFA HI' (should be RRFS HI) and line 49 shows '26 - RRFS PR', but this is a Puerto Rico config file using InputForcings = [26]. The comment at line 47 shows '24 - RRFS NA'. Consider reordering or clarifying the documentation.

Suggested change

# 26 - RRFS PR

Date format appears to be placeholder text ('syyyymmdy0000' and 'eyyyymmdy0000') rather than valid date format. Should be in YYYYMMDDHHMM format as noted in comment at line 107, e.g., 202412230000.

Suggested change

BDateProc = syyyymmdy0000

EDateProc = eyyyymmdy0000

BDateProc = 202412230000
