i-Box (Innsbruck Box) – processed eddy-covariance data: 2-min statistics

The i-Box dataset contains processed eddy-covariance data from five stations in the Austrian Inn Valley, aggregated to 2-minute statistics. Data was collected between 2014 and 2020 by researchers at Universität Innsbruck to study boundary-layer processes in mountainous terrain. Each station is equipped with sonic anemometers and gas analyzers, with specific instrumentation detailed for each site.

Use Cases

• Analyzing turbulent heat and momentum fluxes based on 2-minute eddy-covariance statistics.
• Studying the influence of complex terrain on boundary-layer processes based on data from five stations at different valley positions.
• Validating and improving numerical weather prediction models for mountainous regions based on high-frequency atmospheric measurements.
• Investigating temporal trends and variability in surface-atmosphere exchange based on a seven-year observational record.

Strengths

• Data spans seven years from 2014 to 2020, providing a multi-year observational record.
• Includes measurements from five distinct stations with detailed location and instrumentation metadata.
• Stations cover varied terrain positions including valley floor, sidewall foot, plateau, and slopes up to 25 degrees.

Limitations

• Data gaps occur due to instrument malfunctions and maintenance, as noted in the description.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
