Quantifying proximity, confinement, and interventions in disease outbreaks: a decision support framework for air-transported pathogens
The inability to communicate how infectious diseases are transmitted in human environments has triggered avoidance of interactions during the COVID-19 pandemic. We define a metric, Effective ReBreathed Volume (ERBV), that ... -
Data associated with, "Methane emissions from gathering and boosting compressor stations in the U.S.: Supporting volume 3: Emission factors, station estimates, and national emissions"
This section provides an overview of the field campaign for the entire project and the data collected in the field campaign data and during the analysis phase of the project. -
Data associated with, "Methane emissions from gathering and boosting compressor stations in the U.S. Supporting volume 2: Compressor engine exhaust measurements
The in-stack tracer method was used during the field campaign to measure unburned methane entrained in the exhaust of natural gas compressor engines ("combustion slip"). Combustion slipwas estimated by injecting a tracer ... -
Data associated with "Methane emissions from gathering and boosting compressor stations in the U.S. Supporting volume 1: Multi-day measurements of pneumatic controller emissions"
This study was part of a larger study (the Gathering Emission Factor, or "GEF") study [1] to develop activity and methane emission factors for EPA's Greenhouse Gas Inventory (EPA GHGI) using direct emission measurements ... -
Characterization of methane emissions from gathering compressor stations: final report
This document is the final report to the U.S. Department of Energy (DOE) for contract DE-FE0029068 awarded to Colorado State University (CSU). CSU and subcontractor AECOM partnered with nine U.S. midstream operators to ... -

Dataset associated with "A laboratory assessment of 120 air pollutant emissions from biomass and fossil fuel cookstoves
Cookstoves emit many pollutants that are harmful to human health and the environment. However, most of the existing scientific literature focuses on fine particulate matter (PM2.5) and carbon monoxide (CO). We present an ... -
Dataset associated with "Temporal variability largely explains difference in top-down and bottom-up estimates of methane emissions from a natural gas production region"
This study is the first to spatially and temporally align top-down and bottom-up methane emission estimates for a natural gas production basin, using multi-scale emission measurements and detailed activity data reporting. ... -
Mid-continent basin - methane emissions reconciliation: facility level emissions
Summary of results methane emission reconciliation for facility-level emissions using several measurement techniques during a comprehensive measurement campaign in a mid-continent basin. Comparison of bottom up versus top ... -
Data associated with the manuscript: Investigating diesel engines as an atmospheric source of isocyanic acid in urban areas
Isocyanic acid (HNCO), an acidic gas found in tobacco smoke, urban environments and biomass burning-affected regions, has been linked to adverse health outcomes. Gasoline- and diesel-powered engines and biomass burning are ...
