Licence | Shapefiles are processed and made available as soon as possible after a snowstorm event. The database does not update on a regular basis as snowstorms arrive irregularly. |
Lineage | The Snowfall Database uses Global Historical Climatatology Network - Daily (GHCN-D), which has automated quality control built into its processing. Once the starting and ending dates of a snowstorm are identified, daily data from GHCN-D is extracted and brought into ArcGIS. At that point an analyst removes stations that are not part of the storm. Stations that were part of the storm are checked to ensure that only days with snowfall are included in the snowfall total. The data is then checked for any stations whose total snowfall is statistically different from it's neighbors using Local Moran's Index (see documentation). Stations flagged from this test are checked for spatial consistency. It is assumed that all data is correct unless there is enough evidence otherwise. The station may be kept or rejected, but not values are changed. The analyst then looks for any stations that appear spatially inconsistent with its neighbors. Some of the factors that can make a station or stations appear spatially in consistent are topography, lake effect snow, changes in temperature during the storm (wet vs. dry snow), and spatial variability. |
