COBRA Factsheet Series

The COBRA Factsheet Series includes brief documents with information on how to conduct specific types of analyses in COBRA, including where to find data to estimate emissions inputs and how to analyze the results. EPA plans to add to this series with factsheets for additional types of analyses using COBRA.

Sources of Data for COBRA Inputs

The inputs for COBRA are changes in air pollution emissions of fine particulate matter (PM2.5), sulfur dioxides (SO2), nitrogen oxides (NOx), ammonia (NH3), and volatile organic compounds (VOCs). This factsheet lists sample sources of data that can be used to develop inputs to conduct analyses in COBRA.
