Not listed PURPOSE: THIS PROJECT WILL EXTEND A HIGH-RESOLUTION, HYDROLOGICALLY-ENHANCED LAND-HYDROLOGY MODELING SYSTEM TO THE GLOBAL DOMAIN. IN DOING SO, THIS WORK WILL DIRECTLY LEVERAGE PRIOR WORK THAT HAS BEEN COMPLETED WHICH CONNECTS THE CURRENT NOAA NATIONAL WATER MODEL CONFIGURATION OF THE NOAHMP/WRF-HYDRO MODEL WITH THE EMERGING NOAA/NCEP UNIFIED FORECAST SYSTEM (UFS), AND ASSESSES THE IMPACT OF THIS LAND-HYDROLOGY SYSTEM IN 2-WEEK TO 3 MONTH PREDICTIONS, WHICH WILL ULTIMATELY INCLUDE OTHER EARTH SYSTEM COMPONENTS (OCEAN, SEA-ICE, ETC.). THE WORK WILL SIGNIFICANTLY IMPROVE LAND SURFACE MODEL SOPHISTICATION, LAND SURFACE HYDROLOGY REPRESENTATION, AND THE REPRESENTATION OF TERRESTRIAL PROCESSES INTERACTING WITH THE ATMOSPHERE, ALL AIMED TOWARD IMPROVED OPERATIONAL FORECAST SKILL AND MODEL FIDELITY ON A SPECTRUM OF TIME SCALES. ACTIVITIES TO BE PERFORMED: THE RESEARCHERS WILL DEVELOP AN UPDATED GLOBAL LAND AND HYDROLOGY BASIS (I.E. LAND SURFACE AND HYDROLOGY PARAMETERS AND SPATIAL MAPPINGS OF PARAMETERS, WATERSHEDS AND RIVER NETWORKS) FOR A UNIFIED MULTI-PHYSICS LAND-HYDROLOGY SYSTEM, WITH APPLICATION TO GLOBAL AND REGIONAL PREDICTION SYSTEMS WITHIN THE UFS. THEY WILL IMPLEMENT ENHANCED NEAR SURFACE HYDROLOGIC PHYSICS REPRESENTATIONS INTO THE NOAHMP LAND SURFACE MODEL UTILIZED WITHIN UFS. THEY WILL THEN PERFORM UNCOUPLED (LAND ONLY) AND COUPLED (LAND-ATMOSPHERE) MODEL RUNS OF THE ENHANCED MODEL AND CONDUCT ANALYSES OF THE SPATIAL AND TEMPORAL CHANGES IN THE TERRESTRIAL WATER BUDGET, INCLUDING ATMOSPHERIC FLUX COMPONENTS. FINALLY, THE RESEARCHERS WILL EXECUTE AND EVALUATE RETROSPECTIVE PREDICTABILITY FORECAST EXPERIMENTS AND DEVELOP A LONG-TERM PLAN FOR THE OPERATIONAL PATHWAY OF THIS IMPROVED LAND- HYDROLOGY SYSTEM FOR THE UFS FOLLOWING THE UFS STRATEGIC PLAN. EXPECTED OUTCOMES: THE PROJECT WILL PROVIDE AN ENHANCED LAND-HYDROLOGY CAPABILITY TO UFS AT NOAA, EXTENDING THE CURRENT NOAH-MP LAND SURFACE MODEL FROM A REGIONAL TO GLOBAL DOMAIN, FOLLOWED BY A GLOBAL LAND-HYDROLOGY (NOAH-MP AND WRF-HYDRO, SIMILAR TO THE OPERATIONAL NWM) MODEL, AND THEN A COUPLED LAND-HYDROLOGY-ATMOSPHERE SYSTEM TO IMPROVE MODEL CAPABILITIES ACROSS A RANGE OF FORECAST TIMESCALES WITH GREATEST ANTICIPATED FORECAST SKILL IMPACT ON S2S TIMESCALES. INTENDED BENEFICIARIES: THE ULTIMATE RECIPIENT BENEFICIARY WOULD BE THE NCEP ENVIRONMENTAL MODELING CENTER (EMC) TO SUPPORT EMC?S MODELING MISSION, WITH THE CURRENT GOAL OF UNIFYING EARTH SYSTEM MODELS FOR WEATHER AND SUBSEASONAL TO SEASONAL PREDICTION, I.E. THE NOAA UFS. SUBRECIPIENT ACTIVITIES: THE RECIPIENT DOES NOT INTEND TO SUBAWARD FUNDS. HOWEVER, ADDITIONAL FUNDS ARE AWARDED TO NCAR/UCAR (NA22OAR4590508; CO-PI: DAVID GOCHIS) SUBMITTED AS A PAIRED PROPOSAL. $0 7/21/25 Not listed PURPOSE: THIS PROJECT WILL EXTEND A HIGH-RESOLUTION, HYDROLOGICALLY-ENHANCED LAND-HYDROLOGY MODELING SYSTEM TO THE GLOBAL DOMAIN.
