CAMEX-4 ER-2 Dropsonde Atmospheric Profile Data

The CAMEX-4 ER-2 High Altitude Dropsonde dataset contains atmospheric state parameters measured by GPS-equipped dropwinsondes during the CAMEX-4 field campaign. The National Aeronautics and Space Administration collected this data, with measurements transmitted from the sonde's release until ocean impact at a rate of once per half-second. The dataset's presence across multiple platforms indicates its established use in the research community.

Use Cases

• Analyzing vertical profiles of temperature and humidity for atmospheric modeling.
• Studying wind speed and direction in the upper atmosphere to understand storm dynamics.
• Validating satellite-derived atmospheric data using in-situ dropsonde measurements.
• Investigating pressure gradients and their relation to weather systems during the CAMEX-4 campaign.

Strengths

• Data provides high-frequency measurements at a half-second interval during descent.
• Includes multiple key atmospheric parameters: temperature, humidity, wind speed/direction, and pressure.
• Sourced from the authoritative NASA organization.

Limitations

• Specific row counts, file sizes, and column names are not provided by any source.
• Sources conflict on the last updated date, with one listing 2001-09-24 and another listing 2026-03 13.
