Abstract
In March of 2017, a series of methane release experiments were undertaken at the PG&E Livermore training facility over a three day period. A sUAS equipped with an Open Path Laser Spectrometer (OPLS) was flown and used to detect and localize the emission sources. The experiments included a variation of shared and blind configurations between the facility operators and the sUAS team. This data set include the flight trajectories, wind speed, and concentration measurements.

Description of the data and file structure
This data set describes the measurement data collected during a 3 day controlled release test at the Pacific Gas and Electric Livermore Facility test site. The site consists of multiple residential style buildings with multiple leak sources for testing and training on leak detection technologies and standards.
The test configurations and leak locations are given in the following thesis:
