CROSSINN: Doppler Wind Lidar Measurements in the Inn Valley, Austria (2019)

Two Doppler wind lidars collected data from 14 June to 10 October 2019 during the CROSSINN field campaign in the Inn Valley, Austria. The data includes 1 Hz radial velocity and backscatter profiles from PPI scans and vertical stares, as well as derived vertical wind profiles. Alexander Gohm from Universität Innsbruck authored this dataset, which was published under an Open Access (green) license.

Use Cases

• Studying multi-scale three-dimensional flow structure across a valley based on dual-Doppler lidar measurements.
• Analyzing the impact of cross-valley flow on the mountain atmospheric boundary layer (MoBL) structure and evolution.
• Validating or improving numerical weather prediction models for complex terrain using high-resolution wind profiles.
• Investigating instrument performance and data correction techniques for scanning Doppler wind lidars.

Strengths

• Data covers a specific 4-month field campaign from June to October 2019, providing a focused temporal snapshot.
• Includes measurements from two distinct lidar instruments (SL88 and SLXR142) at precisely defined geographic coordinates.
• Provides both raw 1 Hz data and derived products like vertical wind profiles calculated using the VAD technique.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale machine learning tasks.
• The SLXR142 VAD product coverage is shorter (21 June to 10 Oct 2019) than its 1 Hz data coverage.
