EXRAD Radar Data for Eastern Pacific Hurricane Study

Eastern Pacific hurricane data from the NASA EPOCH project includes radar reflectivity and Doppler velocity estimates. Measurements were collected by the EXRAD instrument onboard an AV-6 Global Hawk UAV during August 2017. This dataset serves both scientific goals for studying tropical cyclogenesis and training goals for developing NASA's next-generation airborne science leadership.

Use Cases

• Analyzing radar reflectivity columns to study precipitation structure within developing hurricanes.
• Using Doppler velocity estimates to investigate wind fields and storm dynamics.
• Training machine learning models for storm intensification prediction using time-series radar observations.
• Calibrating satellite-based precipitation measurements with airborne radar data.
• Studying the spatial evolution of storms across the Eastern Pacific region covered by the flight paths.

Strengths

• Data originates from NASA's authoritative airborne science program.
• Provides a focused temporal snapshot from August 9 to August 31, 2017.
• Cross-platform presence on Data.gov and NASA EarthData indicates recognized importance.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the 'last updated' date (2026-03-13 vs. 2017-08-31).
• License information is unclear ('other-license-specified' on Data.gov vs. 'None' on NASA EarthData).
