Nitrogen Dioxide Trends for US Power Plants

 

Find data and information by state for the top power plants in the US.  The correspondence is generally great between variations and trends in OMI NO2 levels and power plant NOx emissions reported to the Continuous Monitoring Emissions System (CEMS).  However, there are many factors that can influence NO2 levels above a power plant, including changes in regional background levels, other nearby sources, etc. Consequently, we do not provide data for power plants in the Northeast US.  See Duncan et al. (2013) for a detailed discussion on this topic.


Make your own plots!  Please download either our ASCII file or our Excel file, which contain monthly-averaged OMI NO2 data over 150 US power plants.  The file can easily be imported in Microsoft Excel, for instance, for quick data plotting.
