Antarctic Brewer Ozone Spectroscopy Measurements 2016-2020

2016 to 2020 Brewer Ozone spectroscopy measurements from the Jang Bogo Station in Antarctica. The dataset contains total ozone column data derived from light absorption in the 286.5 nm to 363 nm wavelength range. It was produced by the AMD_KOPRI organization for monitoring meteorological variable changes.

Use Cases

• Analyze temporal trends in total ozone column (O3) over the 5-year Antarctic observation period.
• Correlate ozone measurements with seasonal cycles using the daily timestamp data inherent in the time-series.
• Validate satellite-based ozone retrievals using ground-truth Brewer spectroscopy data from a specific geographic point.
• Study the impact of polar atmospheric phenomena on ozone concentration using the high-precision wavelength absorption data.

Strengths

• Five consecutive years of continuous ozone monitoring from 2016 to 2020.
• Data sourced from the Brewer instrument, known for accurate ozone spectroscopy measurements.

Limitations

• Sample size and data density (e.g., daily vs. hourly readings) are unknown.
• Geographic coverage is limited to a single station (Jang Bogo), restricting spatial analysis.
• Data is temporally stale, with the last update recorded in March 2020.
