Domain and Setup
• Two six-month 30km simulations starting Feb 25
• 2002 and 2010• Spin-up soil for one
year using offline HRLDAS
• IC/BC from NARR• CAM radiation; YSU;
Thompson
LSM Setup• Default Noah LSM• Noah-MP with OPT_RUN=3: free drainage
comparable to Noah runoff scheme• Noah-MP with OPT_RUN=5: Miguez-Macho & Fan
groundwater with equilibrium water table• Noah-MP with OPT_BTR=1(Noah) and 2 (CLM)

Summary• Tested a new groundwater option to Noah-MP that
accounts for aquifer interaction with lateral flow• Noah-MP performs better than Noah for near surface
temperature (with exceptions), though more optimization is likely required
• Noah-MP performs the same (2002) or regionally worse (2010) for precipitation
• In regions with low water table depth, upward transport of water:– Increases late summer latent heat flux– Has little effect on precipitation– Improves surface temperature simulation
