Scenarios Network for Alaska + Arctic Planning (SNAP) Tools
The Scenarios Network for Alaska + Arctic Planning (SNAP) website hosts a variety of tools to support climate science and data exploration for the state of Alaska and the Arctic near the northern polar extremes. SNAP tools allow for a local focus within the broader context of climate change.
Available tools include:
- Community Charts, used to explore temperature and precipitation histories and projections for thousands of communities across Alaska and Canada.
- Daily Precipitation helps users analyze historical and projected daily precipitation amounts for communities across Alaska.
- Extreme Weather explores CMIP5 quantile-mapped daily data to analyze the frequency of extreme daily temperature and wind events from 1958 and projected through 2100.
- Historical Sea Ice Atlas permits users to view historical sea ice data collected between 1850 and the present on an interactive map depicting the seas off northern Alaska.
- Modeled Sea Ice Coverage allows users to explore and visualize various models of historical and projected arctic sea ice extent and concentration through 2099.
- Regional Climate Projections uses an interactive map for browsing and comparing climate scenarios created from SNAP data.
- Sea Ice and Wind lets users examine projected interactions between monthly sea ice concentrations and extreme wind events.
SNAP datasets are available for download so that researchers and community members can use them in their own research and in community climate analyses. Data and tools are available in a range of formats, allowing for more intensive use by tech-savvy groups and individuals, but are also accessible to the general public.
SNAP resources, projects, and tools are integrated with the Local Environmental Observers (LEO) Network, the Guidelines for Considering Traditional Knowledges in Climate Change Initiatives, and others to ensure the best blend of climate science and native science to understand local and regional climate trends as they most directly affect Alaska Natives' unique subsistence lifestyles and traditions.
