Silalirijiit Project: Arctic Weather Station Network at Clyde River, Nunavut

Three weather stations at Akuliaqattak, Silasiutitalik, and Ailaktalik, plus data from Kangiqtugaapik Airport, have collected environmental measurements since June 2010. The Silalirijiit Project links this local-scale environmental modeling with Inuit knowledge to evaluate the impacts of changing weather on human activities. Data collection is ongoing, with current conditions available via an online interface, and future archiving planned at the National Snow and Ice Data Center (NSIDC).

Use Cases

• Analyzing long-term Arctic surface temperature and soil temperature trends from in-situ station records.
• Modeling local wind patterns and atmospheric pressure using surface wind speed, direction, and pressure data.
• Studying radiation budgets and cloud cover effects with incoming solar and outgoing longwave radiation measurements.
• Assessing humidity and water vapor indicators for regional climate and permafrost studies.
• Correlating Environment Canada airport station data with community-based station observations for validation.

Strengths

• Provides continuous, in-situ meteorological measurements from a remote Arctic region since June 2010.
• Integrates data from four distinct locations, including a government-operated airport station for comparison.
• Funded by a specific National Science Foundation grant (ARC-0753854), indicating peer-reviewed research context.
• Designed to link physical measurements with Inuit knowledge, adding a unique socio-environmental dimension.

Limitations

• Column names and data structure are not specified in any source, limiting immediate usability.
• Exact data volume (row count, file size) is unknown across all platforms.
• The data is currently presented via a live interface rather than a static, downloadable archive, though future NSIDC archiving is planned.
