Description:

The Noah-MP land surface model (LSM) relies on the Monin-Obukhov (M-O) Similarity Theory (MOST) to calculate land-atmosphere exchanges of water, energy, and momentum fluxes. However, MOST flux-profile relationships neglect canopy-induced turbulence in the roughness sublayer (RSL) and parameterize within-canopy turbulence in an ad hoc manner. We implement a new physics scheme (M-O-RSL) into Noah-MP that explicitly parameterizes turbulence in RSL. We compare Noah- MP simulations employing the M-O-RSL scheme (M-O-RSL simulations) and the default M-O scheme (M-O simulations) against observations obtained from 647 Snow Telemetry (SNOTEL) stations and
