Analysis of Snow Climatology

How this map was made:

For each seasonal snowfall year (October-March), one gridded map was generated based on the individual station observations using a kriging technique. From this, a software procedure extracted the 25th percentile snowfall statistic for each gridpoint, based on the entire distribution for the given number of seasons. The units represent an annual snowfall total (inches) in which 25% of the observation are below the given value.
