Landsat Fractional Snow Covered Area Science Products

Snow cover is spatially and temporally variable and is often concentrated in remote or inaccessible land regions making spaceborne remote sensing the most feasible approach to measure and monitor snow cover change. Landsat’s spatial resolution offers the capability to resolve snow cover patterns across topographically complex mountainous regions.

Return to Landsat Science Products Overview

 

While Landsat’s acquisition frequency limits analysis of short-term snow cover variations, longer term changes in snow cover duration and persistence can be detected. Landsat Fractional Snow Covered Area (fSCA) products provide per-pixel fractional snow cover maps that indicate the percentage of a pixel covered by snow. 

The table below displays how different communities use Landsat fSCA products in their research. 

Community Potential Use
