摘要: Abstract Fresh snowcover in a remote upland catchment is chemically heterogeneous. Coefficients of variation (Cof) for individual major ions range from 5 to 113%, assuming normal distribution, or 1 144 % lognormal distribution. Aged slightly more variable, giving rise Cof 19–140 %, 2–200 In general, the distribution concentration better described by Both vertical and horizontal variability observed chemical content within-pack snows. Such heterogeneity has important implications snowpack sampling. We suggest that rigorous methodologies should be devised sampling fresh snowcover. The snows also performed under tight statistical constraints if representative estimates solute are obtained.
