NASA ER-2 Aircraft Navigation Data for Olympic Mountains Experiment

Aircraft navigation data was collected by the NASA ER-2 high-altitude research aircraft during the Olympic Mountains Experiment (OLYMPEX) field campaign. The dataset contains multiple flight parameters including altitude, pressure, temperature, airspeed, and ground speed for flights occurring from November 9 to December 15, 2015. It is provided by the National Aeronautics and Space Administration as part of the Global Precipitation Measurement (GPM) Ground Validation efforts.

Use Cases

• Validating satellite precipitation measurements by correlating aircraft flight paths with ground-based radar data.
• Analyzing aircraft performance parameters like airspeed and ground speed under specific meteorological conditions.
• Studying atmospheric profiles using in-flight measurements of altitude, pressure, and temperature.
• Synchronizing data collection timelines from multiple instruments during a coordinated field campaign.

Strengths

• Data originates from a controlled NASA field campaign (OLYMPEX), ensuring a defined collection methodology.
• Covers a specific 37-day time range (November 9 - December 15, 2015) for focused analysis.
• Includes multiple critical flight parameters: altitude, pressure, temperature, airspeed, and ground speed.
• Available in structured formats (ASCII, ASCII-IWG1, XML) suitable for programmatic analysis.

Limitations

• Exact row count, file size, and complete column schema are not provided by any source.
• Sources conflict on the most recent update date: one lists 2026-03-13, another lists 2015-12 15.
