Upper Air Observations from Jang Bogo Station, Antarctica in 2017

Regular upper air observations were made once daily at 00 UTC from February to November 2017 using radiosondes. Data for pressure, temperature, relative humidity, wind speed, and wind direction were sampled every two seconds, reaching a minimum observation height over 20 km. The dataset was collected by AMD_KOPRI to monitor changes in meteorological variables with altitude over the Jang Bogo station.

Use Cases

• Modeling vertical atmospheric profiles based on pressure, temperature, and humidity data.
• Analyzing wind patterns and jet streams based on wind speed and direction measurements.
• Studying seasonal atmospheric changes in Antarctica based on data collected from February to November.
• Calibrating satellite or remote sensing data with in-situ upper air observations.

Strengths

• High-frequency data sampling recorded every two seconds.
• Observations reach a minimum height of over 20 km, providing a substantial vertical profile.
• Data collection spans a significant portion of the year, from February to November.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
