version 2.7.1 of Noah (N2.7), the z 0m is defined as a function of land cover (specified as 0.035 m for grassland and 0.011 m for bare soil), and the Reynolds number–dependent formulation proposed by Zilitinkevich (1995) is implemented for the z 0h calculation ( Chen et al. 1997 ): and where ν is the kinematic molecular viscosity (taken as 1.5 × 10 −5 m 2 s −1 ). C zil is an empirical constant and specified as 0.1 in Noah 2.7.1 analogous to values derived from measurements over grassland
