MAX-DOAS Atmospheric Spectra and Sensor Data from Southern Ocean Voyage

MAX-DOAS spectra and auxiliary sensor data collected aboard the Aurora Australis in the Southern Ocean. The dataset includes daily spectral files, log files with geometric and temperature data, accelerometer readings, and contextual images. It was produced by the AU_AADC organization and last updated in March 2019.

Use Cases

• Analyzing solar zenith angle and latitude/longitude from daily logs to model atmospheric light paths for trace gas retrieval.
• Using pitch, roll, and yaw Euler angles from accelerometer files to correct for ship motion effects on spectral measurements.
• Correlating instrument temperature measurements with spectral calibration files to assess data stability.
• Classifying broad light conditions (sunny/cloudy) using co-directional camera images to filter spectra for analysis.

Strengths

• Includes multiple data modalities: spectra, geometric logs, accelerometer data, images, and calibration files.
• Data is organized into daily folders and files, providing a clear temporal structure.
• Spectra are compatible with standard processing software like DOASIS or QDOAS.

Limitations

• Specific row counts, file sizes, and total data volume are unknown.
• The dataset's temporal coverage is not specified beyond the file organization by date.
• No license information is provided, which may restrict use.
