    7474This correction is presently introduced in the code to estimate the potential evaporation of Budyko (or Penman-Monteith, or Thornthwaite), i.e. Ep = rau/ra*[qsat(T*)-qa], or Ep(T*). 
    7575 
    76 This potential evaporation is smaller than the one of ORCHIDEE, which is Ep(Ts)=rau/ra*[qsat(T*)-qa].

    7878Milly, 1992 (Document 6) applies a first-order linearisation of qsat(T) around Ta (like in the derivation of the Penman formula for wet surface evaporation, see Document 7) for qsat(T*) and qsat(Ts). The expressions of Ep(T*) and Ep(Ts) are then found by using the unstressed/stressed energy budget equation respectively (in which the upward LW term is also linearized).
