ATTREX: Global Hawk UAS Meteorological and Navigational Measurements from 2011-2014

The ATTREX campaign collected in-situ meteorological and navigational data onboard a NASA Global Hawk Uninhabited Aerial System during deployments in 2011, 2013, and 2014. The data were gathered by the Meteorological Measurement System over California and Guam to address uncertainties in stratospheric humidity and ozone composition. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling stratospheric humidity climate feedbacks based on water vapor measurements
• Analyzing ozone depletion mechanisms based on bromine-containing gas measurements
• Studying cirrus cloud formation based on particle size and shape data
• Tracking chemical species transport through the Tropical Tropopause Layer based on trace measurements
• Calibrating global climate models based on three-dimensional wind data

Strengths

• Data collection is complete for the specified campaigns
• Campaigns deployed over multiple locations (California, Guam, Hawaii, Australia) and seasons
• Focuses on the critical Tropical Tropopause Layer (~13-18 km altitude)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• File formats include BIN and ISO, which may require specialized tools for access
