Meteorological Forcing Data for ParFlow-CONUS2 Grid

As part of data infrastructure building by the Hydrology Team at the Center for Western Weather and Water Extremes (CW3E), a meteorological forcing engine is developed to produce long-term (1979 to near real time), high-resolution (1-km, 1-hourly), and national-scale (CONUS) forcing data to support research and applications in hydrologic modeling and forecasting. The configuration of this forcing data product is set up to serve the demanding needs at the center, for example, to build near-real-time (NRT) forecasting system for various regions and to perform large scale modeling research for the National Water Model (NWM) (both its current generation WRF-Hydro and its NextGen) in collaboration with the CIROH consortium. See CONUS 1-km Water Monitor & Forecast page (https://www.reachhydro.org/home/forecast/conus-1-km-water-monitor-forecast) for an example of application of this data product.

accessRights Users must create a HydroFrame API account and register their PIN before using the hf_hydrodata package. If it's your first time using this package you will need to sign up for a HydroFrame account on the HydroFrame Signup Page (https://hydrogen.princeton.edu/signup; note: this only needs to be done once). Visit our HydroFrame PIN Page (https://hydrogen.princeton.edu/pin) to create a 4-digit PIN. After creating your PIN, you must register that PIN on the machine that you intend to use.

creationMethod Please see the full methods documentation (https://www.reachhydro.org/home/records/1-km-conus-forcing) for information on the original dataset creation. This version of the dataset has some additional adjustments to temperature and specific humidity for Water Years 2003-2005 at the HUC02 level. Temperature was adjusted as described for each region below. Specific humidity was adjusted anywhere that temperature was adjusted, using the Clausius-Clapeyron equation.

versionNotes Version 1.0: - Second HydroFrame release of the CW3E dataset. Version 0.9: - Initial version of CW3E dataset. - CW3E team: corrected an 11-hour (for P) and 12-hour (for T) time mismatch against PRISM. - HydroFrame team: implemented some additional adjustments to temperature and specific humidity for Water Years 2003-2005 at the HUC02 level. Temperature was adjusted as described for each region below. Specific humidity was adjusted anywhere that temperature was adjusted, using the Clausius-Clapeyron equation. - Water Year 2003: -- Great Basin (HUC 16): 0.5 degree uniform temperature decrease -- Pacific Northwest (HUC 17): 0.5 degree uniform temperature decrease -- Upper Colorado River Basin (HUC 14): temperature lapse rate correction at 4 K/km - Water Year 2004: -- Great Basin (HUC 16): 0.5 degree uniform temperature decrease -- Upper Colorado River Basin (HUC 14): temperature lapse rate correction at 4 K/km - Water Year 2005: -- Upper Colorado River Basin (HUC 14): temperature lapse rate correction at 2.5 K/km
