Multivariate data indexed by spatial coordinates has become ubiquitous in climate, environmental and geo-sciences. This has promoted sustained interest in modeling, estimation and simulation of spatial stochastic processes through multivariate Gaussian random fields. The goal of this dissertation...
Continuous spatial monitoring of air and soil-surface temperatures under natural covers (vegetation and snow) was conducted at an array of Arctic Alaskan sites representing a range of undisturbed tundra landscapes since 1995. This data set was utilized to assess the complex relation between snow...
Climate warming is occurring at an unprecedented rate in the Arctic, seriously impacting sensitive environments, and triggering land cover change. These changes are compounded by localized human influences. This work classifies land cover change for the Lower Yenisei River, identifies those...
