Data utilized for this analysis includes three data sources. First, aerial screening anonymously sampled a dened subset of the DJ basin (hereafter the `study area'). Each detection (a `plume') was also quantied by the aerial team and assigned a location categoryagriculture (`Ag'), waste management (`Waste') and O&G. Second, partner production and midstream operators in the basin provided lists of maintenance events including location (latitude and longitude), type of event, and when the event occurred. Finally, a variety of public data sources were integrated to identify the location and operator(s) of O&G facilities in the study area. Each data source is discussed in the following subsections.
