Correction to: Boundary-Layer Meteorology (2020) 177:427–459 https://doi.org/10.1007/s10546-020-00550-9 In Sect. 3.1 of Cuxart and Boone (2020) the psychrometric constant given two lines below Eq. 10 does not apply to Eq. 10. When Eq. 10 is given in terms of the partial pressure of water vapour e, the psychrometric constant γ has to take the form γ =
Rv C p p. Rd λ

The expression γ = C p /λ applies when the Penman equation is given in terms of the specific humidity s (Rn − G) ρ C p [qsat (Ta ) − qa ] λE p = . (2) + s+γ rae (s + γ ) Here Rd and Rv (J kg−1 K−1 ) are the specific gas constants for dry air and water vapour, λ (J kg−1 ) is the enthalpy of vaporization of water, Rn (W m−2 ) is the net radiation, G (W m−2 ) is the ground heat flux, E p (kg m−2 s−1 ) is the evapotranspiration, C p (J kg−1 K−1 ) is the specific heat capacity of air at constant pressure, s (K−1 ) is the slope of the saturated specific humidity curve at the air temperature Ta (K), ρ is the air density (kg m−3 ), qa (kg kg−1 ) is the specific humidity of the air and qsat is the saturating value at Ta and rae (s m−1 ) is the aerodynamic resistance.
