The following sets of images and plots are comparisons for the dates
when the Corps of Engineers performed snow surveys. For each date,
the upper left subimage contains surveyed Army SWE data (converted
from inches to mm) for the Oahe basin. Each subsequent subimage is
one of the passive microwave algorithm outputs for the same date,
masked for the basin area only. The red outline in the PM images is
the outline of the Army data SWE extent. The plots contain scatter
plots of the Army data vs. each algorithm output. Only SWE values are
considered (i.e. "wet" snow flags and pixels with missing TBs are
eliminated).
