Depolarization lidar measurements from a specialized CAPABL system deployed at Summit Station, Greenland. The dataset includes parameters like parallel channel backscatter, depolarization ratio, and diattenuation, collected by NOAA's Earth System Research Laboratory with NSF support. Data files were last updated in 2020.
Use Cases
- Classify cloud phase and type using the depolarization ratio and backscatter measurements.
- Quantify aerosol load and type in the Arctic atmosphere by analyzing the diattenuation and backscatter signals.
- Study vertical profiles of atmospheric constituents from the near-vertical pointing lidar's time-series data.
- Validate satellite-based lidar products like those from CALIPSO using ground-based parallel channel backscatter comparisons.
Strengths
- Data originates from a dedicated, research-grade Cloud and Aerosol Polarization and Backscatter Lidar (CAPABL) system.
- Measurements include three distinct polarization states (backscatter, depolarization ratio, diattenuation) for detailed analysis.
- Collected at Summit Station, Greenland, a unique Arctic high-altitude observatory location.
Limitations
- The dataset's temporal coverage and total volume (row count) are unspecified.
- Data is from a single geographic location, limiting spatial generalizability.
- Last update was in 2020, which may not reflect recent atmospheric conditions.
