Daily Polar Stratospheric Cloud Observations from Davis Station Lidar

Daily lidar observations from Davis Station, Antarctica, measure the occurrence and altitude limits of Polar Stratospheric Clouds (PSCs). The data, collected by the AU_AADC, are considered obsolete and were last updated in 2001. It provides condition indicators for studying cloud formation linked to ozone depletion chemistry.

Use Cases

• Analyze daily PSC percentage_occurrence trends to correlate with stratospheric temperature records.
• Model relationships between PSC lower_altitude_limit and upper_altitude_limit data and volcanic event timelines.
• Study the temporal variability of cloud detection to understand conditions favorable for heterogeneous chlorine activation.

Strengths

• Provides daily resolution data for key atmospheric indicators.
• Uses dual measurement techniques: Rayleigh and Doppler lidar modes at 532nm wavelength.

Limitations

• Dataset is marked as obsolete and not maintained, with the last update in 2001.
• Spatial coverage is limited to a single location: Davis Station, Antarctica.
• Specific row counts, sample sizes, and data completeness metrics are unknown.
