Phenology: observed. Cold sterility: default (Eq 22), new with minimum rule (Eq 28) or new with averaging rule (Eq 27). Heat fertility: default (Eq 14) or new (Eq 20). Combined fertility: minimum or product of heat and cold fertility. EF = modelling efficiency (Eq 32) for the two sites combined and separately for the two sites. max() LAIMAX is the maximum LAI recorded over all 30 simulations.
