Abstract:

The Sierra Nevada snowpack is one of the primary water resources for California. Precipitation occurs predominately in the winter and spring months in this region. In recent decades, snow pillow records provide a set of spatially-located functional data describing the snowpack accumulation and melt patterns in each year at each snow pillow location. We present a functional data analysis study of space-time variation in the annual snowpack accumulation and melt patterns, associated with spatial location attributes and large-scale climate indices.
