Abstract:

The data file defines a global seasonal snow classification system.

Based on the physical properties of the snow (depth, density, thermal

conductivity, number of layers, degree of wetting, etc.), the world's

seasonal snow covers were divided into six classes, plus classes for

water and ice fields. Each class was defined by its physical properties,

then empirically related to climate using three variables

(precipitation, wind, and air temperature). A vegetation proxy was used

for wind data: tall vegetation equals low wind, short vegetation equals

high wind.

The snow classification data are formatted into an array of integers,

each value representing a 0.5-degree latitude by 0.5-degree longitude

cell. The data set was developed and tested for the Northern Hemisphere.

Results for the Southern Hemisphere are untested and have not been

evaluated. The Southern Hemisphere suffers from a reduced density of

meteorological data which may well have influenced the quality of the

snow classification in that area. Also note that much of Antarctica is

inappropriately defined as water (the vegetation data set did not extend

that far south). A 0.5- x 0.5-degree land-sea mask could be used to set

the Antarctica region to the ice classification if this region is of

interest.
