SMEX02 Radiosonde Upper Air Measurements from Iowa

SMEX02 Balloon-borne Radiosonde Data, Iowa, Version 1 contains measurements of upper air temperature, pressure, relative humidity, wind direction, and wind speed collected via radiosonde during balloon ascents. The dataset is provided by the National Snow and Ice Data Center (NSIDC). Sources indicate updates in 2002 and 2026, suggesting ongoing curation.

Use Cases

• Analyzing vertical profiles of atmospheric temperature and pressure.
• Studying humidity and dew point variations with altitude.
• Investigating upper-level wind speed and direction patterns.
• Validating or calibrating satellite-derived atmospheric data.
• Examining vertical wind motion and atmospheric stability.

Strengths

• Provides multi-parameter atmospheric profiles (temperature, pressure, humidity, wind).
• Cross-platform presence on NASA Earthdata and Data.gov signals recognized importance.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Sources conflict on the last updated date, listing both 2002-07-09 and 2026-03-12.
