It is defined as: N S E = 1 − ∑ t = 1 T ( Q o t − Q m t) 2 ∑ t = 1 T ( Q o t − Q ― o) 2 where Q ― o is the mean of observed discharges, and Q m is modeled discharge. Q o t is observed discharge at time t. [1]

http://www.history-of-hydrology.net/mediawiki/index.php?title=Nash,_Eamonn WitrynaTraditionally, the Nash–Sutcliffe efficiency (NSE, Nash and Sutcliffe, 1970) is an often-used metric, in part because it normalizes model performance into an interpretable scale (Eq. 1): where T is the total number of time steps, Qsim(t) the simulated discharge at time t, Qobs(t) the observed discharge at time t, and the mean observed discharge.
