Abstract

Inter-stake correlations and noise are very sensitive to gross errors in the data, while climate signal is less sensitive. Low values of inter-stake correlations are used to detect suspect data, and elimination of such data reduces the noise standard deviation from ±0.40 to ±0.28m water a-1 for 6 years of record compared with a climate signal of ±0.55m water a-1. The climate signal on Qamanarssup is positively correlated with summer mean temperature and negatively correlated with annual precipitation. -from Authors
