BOREAS Ground Sunphotometer Aerosol Measurements from 1994

Candle Lake, Saskatchewan, Canada, was the location for ground-based sunphotometer measurements collected during the BOREAS project. The RSS-12 team gathered these time-series data on selected days from May to September 1994 to characterize aerosol optical properties. Measurements were intended to quantify aerosol optical depth, study boreal aerosols, and support atmospheric correction of remote sensing data.

Use Cases

• Analyzing the magnitude and temporal variability of aerosol optical depth using time-series measurements.
• Determining the optical properties of aerosols specific to the boreal forest environment.
• Applying atmospheric correction to co-located remotely sensed data from the BOREAS campaign.
• Studying seasonal changes in atmospheric aerosols during the boreal summer of 1994.

Strengths

• Data collection was part of the structured BOREAS project, ensuring a defined scientific purpose.
• Temporal coverage is precisely documented across a five-month period in 1994.
• Measurements were taken from specific ground sites, providing controlled location data.

Limitations

• Key technical details like row count, file size, and specific column names are unavailable from all sources.
• There is a conflict in the 'last updated' metadata, with dates ranging from 1994 to 2026.
• The data format is unclear, with sources listing multiple possible but unconfirmed file types.
