Internal Gravity Wave Observations from SACOL Station, December and November 2023

Two nighttime observation periods from late 2023 provide data on internal gravity waves in a stable boundary layer. The dataset was collected at the Semi-Arid Climate and Environment Observatory (SACOL) station in Lanzhou, China, using three tower-based eddy covariance systems, a Doppler wind lidar, and a meteorological gradient tower. Processed data supports figures and analysis in an associated manuscript.

Use Cases

• Analyzing wave-packet evolution based on high-frequency meteorological and wind data.
• Studying wave-turbulence interaction mechanisms within a stable boundary layer.
• Validating or developing models for internal gravity wave behavior over complex terrain.

Strengths

• Data is sourced from a specialized climate observatory (SACOL) at 1965.8 m altitude.
• Combines measurements from three eddy covariance systems, a Doppler wind lidar, and a gradient tower.
• Covers two distinct nighttime periods in November and December 2023.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (311.7 KB), indicating limited scope or highly processed data.
