BOREAS Cloud and Condensation Level Data from NSA and SSA Sites

Northern Saskatchewan and Manitoba data from the BOREAS project includes ceilometer measurements of cloud fraction, cloud height, and surface-based lifting condensation level. The National Aeronautics and Space Administration collected this information at the NSA-OJP site in 1994 and at both NSA-OJP and SSA-OBS sites in 1996. Data formats include HTML, PDF, PNG, BIN, ISO, ZIP, and TEXT files.

Use Cases

• Analyzing cloud fraction and cloud height time series to study cloud cover dynamics.
• Deriving surface-based lifting condensation level from temperature and humidity to understand atmospheric stability.
• Modeling cloud frequency and properties for boreal ecosystem climate studies.
• Comparing cloud data from two distinct sites (NSA-OJP and SSA-OBS) within the BOREAS region.

Strengths

• Data collected at two distinct sites (NSA-OJP and SSA-OBS) in the BOREAS region.
• Includes derived atmospheric variable (lifting condensation level) from measured temperature and humidity.
• Covers two separate years of observation (1994 and 1996).

Limitations

• Exact row counts, file sizes, and specific column names are not provided by any source.
• Sources conflict on the last updated date: one platform lists 2026-03 -13, while another lists 1996-11-10.
