Arctic Summer Aerosol Profiles from LIDAR Measurements

Summer 2012 LIDAR data captures aerosol back-scattering intensity and depolarization ratio with altitude up to 10 km over the Chukchi Sea. Measurements characterize aerosol profiles and shape, evaluating variation in the atmospheric boundary layer. The dataset was collected by AMD_KOPRI and published via NASA EarthData in September 2012.

Use Cases

• Analyze aerosol back-scattering intensity profiles by altitude to study particle distribution.
• Calculate depolarization ratio variation with height to infer aerosol shape and type.
• Model the atmospheric boundary layer structure over the Chukchi Sea using altitude-resolved measurements.
• Track temporal changes in aerosol profiles during the Arctic summer of 2012.

Strengths

• Vertical profiles extend up to 10 km altitude.
• Includes dual-polarization LIDAR measurements for aerosol characterization.

Limitations

• Dataset size, row count, and specific file formats are unknown.
• Limited to a single summer season (2012) and the Chukchi Sea region.
• Data completeness and potential measurement gaps are unspecified.
