How is the Mohnobov length calculated

[yangwenjing]

In WRF, it is possible to output RMOL=1/L (where L is the Monin-Obukhov length). What formula is used to calculate this L

Hi,

The method of calculating RMOL depends on the turbulence closure schemes and surface-layer parameterizations used in WRF.

Please look at the codes corresponding to the schemes you choose, and find how it is calculated in these specific schemes.
