GRIP DAWN Lidar Wind Profiles for Hurricane Genesis Study

Lidar wind measurements were collected by the Doppler Aerosol WiNd (DAWN) instrument aboard a NASA DC-8 aircraft during the Genesis and Rapid Intensification Processes (GRIP) field campaign. The dataset includes Line-of-Sight winds, vertical profiles of horizontal wind velocity, and frequency-domain signal energy, mapped against time, latitude, and longitude. NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) provides this data from the campaign conducted over the Atlantic Ocean.

Use Cases

• Analyzing vertical wind profiles to study energy transfer during hurricane genesis.
• Correlating Line-of-Sight (LOS) wind data with other in-situ observations from the GRIP campaign.
• Mapping wind velocity and signal energy against latitude and longitude for spatial analysis of storm systems.
• Studying temporal evolution of atmospheric winds during the rapid intensification phase of tropical cyclones.

Strengths

• Data originates from a focused NASA field campaign (GRIP) specifically designed to study hurricane lifecycle.
• Provides specific geospatial and temporal coverage from August 24 to September 22, 2010, over the Atlantic Ocean.
• Includes derived data products like calculated vertical profiles of horizontal wind velocity.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on license (specified as 'other-license-specified' vs. 'None') and last updated date (2026 vs. 2010).
