Abstract
To understand the limitations of current canopy adjustments and advance toward an improved method to account for subcanopy snow, this chapter aims to answer the following research questions: (1) How well do original satellite‐derived fractional snow‐covered area ( ƒSCA ) and canopy‐adjusted ƒSCA approximate subcanopy ƒSCA? ( 2 ) What spatiotemporal snow cover patterns explain differences between in situ snow cover and satellite‐derived ƒSCA? ( 3 ) What canopy structure metrics can account for differences between snow cover and satellite‐derived ƒSCA? To address the research questions, it examines patterns in satellite ƒSCA, in situ snow cover, and forest canopy structure. First, original satellite‐derived ƒSCA and canopy‐adjusted ƒSCA ( ƒSCAADJ ) are both compared against in situ observations of snow cover to assess the currently employed canopy adjustment. The spatial and temporal accuracy of ƒSCAADJ is then examined across multiple study sites, and errors are evaluated by comparing spatial and temporal patterns in forested and open sites.
