High Spectral Resolution Lidar Atmospheric Profiles from Eureka Canada

University of Wisconsin Lidar Group provides high spectral resolution lidar data from Eureka, Canada, collected alongside MMCR radar, PAREI infrared spectrometer, microwave radiometer, and radiosonde data. The dataset includes derived products and quality control masks. Data collection was active through at least May 2010.

Use Cases

• Analyzing cloud microphysics by correlating lidar backscatter profiles with MMCR radar reflectivity.
• Screening for instrument errors using the qc_mask bit 3 and transmitted_energy field to filter periods of low laser energy from July 2009 to May 2010.
• Deriving aerosol optical properties from high spectral resolution lidar channels for atmospheric composition studies.
• Assimilating temperature and humidity profiles from Eureka radiosonde data with lidar-derived boundary layer height.
• Studying Arctic atmospheric thermodynamics by fusing PAREI infrared spectrometer data with lidar extinction coefficients.

Strengths

• Includes multi-instrument data fusion from lidar, radar, spectrometer, radiometer, and radiosonde.
• Provides a documented quality control mask (qc_mask) for identifying unreliable data periods.
• Data collection covers a full annual cycle in the high Arctic environment.

Limitations

• A known instrument failure from July 2009 to May 2010 caused periods of low or zero transmitted energy, requiring careful filtering.
• Specific row counts, column details, and file sizes are unknown.
• The dataset's last update was in May 2010, indicating it is not actively maintained.
