1-minute sampled low-resolution images of hydroxyl airglow over Davis station, Antarctica, from 2017. The data consists of 16x16 pixel arrays representing variations in a 24x24 km region of the night sky approximately 87km above Davis. Observations were made in all cloud conditions between civil twilight each year using a scanning radiometer developed at the University of Western Ontario.
Use Cases
- Analyze temporal variations in hydroxyl airglow intensity based on the 1-minute sampling rate.
- Study spatial patterns within the 24x24 km observation region based on the 16x16 pixel array.
- Model atmospheric conditions affecting infrared emissions in the 1.0-1.6 micron spectral region.
- Correlate airglow observations with other meteorological data collected under all cloud conditions.
Strengths
- Data is sampled at a 1-minute interval, providing high temporal resolution.
- Observations cover a specific 24x24 km region at 87km altitude, offering localized spatial detail.
- Instrument sensitivity covers the 1.0-1.6 micron infrared region encompassing multiple hydroxyl ro-vibrational bands.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the single Antarctic station location.
