Soil moisture variations from boreal forests to tundra
Soil moisture has a profound influence on life on Earth, and this vital water resource varies across space and time. Here, we explore soil moisture variations in boreal forest and tundra environments, with a particular focus on the relationship between soil moisture mean (variation within a study ar...

At all seven areas, the unimodal pattern was found over the entire measurement period. Pairwise distances in a spatio-temporal soil moisture space were more related to topographic differences between the sites (R2 = 0.106), but not to geographical or climatic differences (R2 = 0.003, R2 = 0.003). This indicates that similar spatio-temporal variations in soil moisture are present also over large geographical (>1000 km) and climatic gradients. We also found more spatial than temporal variation within the areas. These results demonstrate the high soil moisture heterogeneity across boreal forest and tundra environments.
