Arctic Wind Profiles from Doppler Lidar at DASAN Station in 2019

Doppler wind lidar data provides vertical wind profiles up to 1.5 km altitude from the DASAN Station in Ny-Alesund, Svalbard. The dataset was collected throughout 2019 by the AMD_KOPRI organization to study Arctic boundary layer structure and cloud-boundary layer interactions. Observations include continuous vertical profiles and horizontal/vertical cross-sections of the wind field via PPI and RHI scanning modes.

Use Cases

• Analyze vertical wind speed and direction profiles up to 1.5 km altitude to characterize Arctic boundary layer structure.
• Study horizontal wind field cross-sections from PPI scan mode data to understand spatial wind variability.
• Investigate vertical wind cross-sections from RHI scan mode data to examine cloud-boundary layer interactions.
• Validate and calibrate atmospheric models using continuous, high-temporal-resolution wind profile measurements from 2019.
• Correlate lidar-derived wind data with other Arctic climate observations from the DASAN Station location.

Strengths

• Continuous data collection throughout the 2019 calendar year.
• Wind profile measurements extend to 1.5 km altitude, covering a significant portion of the boundary layer.
• Includes multiple observation modes: vertical profiles, PPI (horizontal cross-section), and RHI (vertical cross-section).

Limitations

• Specific sample size, row count, and data volume are unknown.
• Data is limited to a single geographic location (DASAN Station, Svalbard).
• Dataset is from 2019 and may not reflect more recent atmospheric conditions.
