16x16 pixel infrared images sampled every minute from a scanning radiometer at Davis station, Antarctica. The instrument, developed at the University of Western Ontario, captures hydroxyl airglow variations in a 24x24 km region of the night sky at approximately 87km altitude. Observations were made in all cloud conditions between civil twilight each year from 1999 to 2016.
Use Cases
- Analyze temporal variations in hydroxyl airglow intensity based on the 1-minute sampling rate
- Study spatial patterns of atmospheric emissions within the 24x24 km observation area
- Model atmospheric dynamics at approximately 87km altitude using infrared observations
- Correlate airglow activity with seasonal changes based on the annual observation window
Strengths
- Long-term temporal coverage spanning 17 years from 1999 to 2016
- High temporal resolution with observations sampled every minute
- Specific spatial coverage of a 24x24 km region at 68 degrees S,78 degrees E
- Observations made in all cloud conditions, increasing data availability
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
