Abstract

Flux PIHM (Penn State Integrated Hydrologic Model) is a fully coupled land surface hydrologic model developed to by incorporating a land-surface scheme into PIHM. The land-surface scheme is mainly adapted from the Noah LSM.

Flux-PIHM (Shi et al., 2013), the surface energy balance scheme completely replaces the original evapotranspiration formulation in PIHM. The land surface and hydrologic components are coupled by exchanging water table depth, soil moisture, infiltration rate, recharge rate, net precipitation rate, and evapotranspiration rate between each other. At each time step, the hydrologic component provides the land surface component with discharge, groundwater level, soil water content in different soil layers, snow depth, evapotranspiration, etc. The volumetric soil moisture contents simulated by land surface component are rescaled using the integrated soil water storage provided by PIHM to guarantee mass conservation. The land surface component then starts with surface energy balance simulation and provides the hydrologic component with net precipitation rate and evapotranspiration rate.

The model has been manually calibrated at Shale Hills using discharge, water table depth, soil moisture, surface heat fluxes, and soil temperature data. The reanalysis data presents estimation of discharge and related hydrologic processes from 01/2015 to 12/2019 to provide temporally and spatially continuous estimation of discharge, groundwater, soil moisture, etc., and to be a supplement of data when observation is not available.
Reanalysis data has been prepared using the model results from Flux-PIHM v 0.14.4 alpha.
