GRIP DC-8 Aircraft Meteorological Measurements for Hurricane Research

August 10 through September 25, 2010, this dataset contains high-resolution meteorological measurements from NASA's DC-8 aircraft during the Genesis and Rapid Intensification Processes (GRIP) field experiment. It provides calibrated parameters like pressure, temperature, and 3D wind vectors at 1 Hz and 20 Hz frequencies to study tropical storm formation. The data was collected by the NASA Meteorological Measurement System (MMS) as part of a multi-aircraft campaign to characterize hurricane lifecycles.

Use Cases

• Analyzing high-frequency (20 Hz) wind vector and turbulence data to study storm dynamics.
• Correlating aircraft GPS position, velocity, and attitude with atmospheric temperature and pressure measurements.
• Investigating relationships between air flow angles (angle-of-attack, sideslip) and true airspeed during storm penetrations.
• Studying the temporal evolution of potential temperature and other derived parameters during the 2010 Atlantic hurricane season.

Strengths

• Provides dual-resolution data streams with a primary 1 Hz and a secondary 20 Hz dataset for detailed temporal analysis.
• Covers a focused 47-day campaign during the peak of the 2010 Atlantic hurricane season.
• Includes post-mission systematic calibration, enhancing accuracy for parameters like 3D winds and temperature.
• Dataset is hosted on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating vetting and importance.

Limitations

• Exact row count and total dataset size are not specified on any platform.
• Sources conflict on the 'last updated' date, with Data.gov listing 2026-03-13 and NASA Earthdata listing 2010-09 -25.
• The specific license is listed only as 'other-license-specified' without detailed terms.
