net balances are wellcorrelated and (obviously) best modelled as the
sum of bw measured and bs modelled (bs-m2). Thebest obtained correlations of modelled bw (0.86), bs(0.87) and bn (0.94) for 1949–2006, show that themodel could explain 73, 76 and
88% of the variance
over this period.From each year we also extracted the day with
maximum bw (bwd) and minimum bs (bsd, mini-mum values as bs is negative
