AERMOD is an air dispersion model that the US Environmental Protection Agency (EPA) recommends for evaluating the dispersion of non-reactive air pollutants emitted by a stationary source. As part of the permitting for The Data Center (TDS), Duffield Associate's Inc. used AERMOD to assess the patterns of pollution generated by the natural-gas power plant that is being proposed as part of TDC. All the paperwork is publicly available here, including the input and output files generated by AERMOD (Appendix F). However, no figures or plots were made available to help the public visualize the plumes spatially over Newark.
The plots in the drop-down menus below were generated by students in my Air Pollution Meteorology class using directly the original AERMOD files that were generated by Duffield Associate's Inc. There are two drop-down menus to help compare side by side, for example, concentrations resulting from full-capacity versus normal operation, or any combinations of pollutants and time averaging desired.
The pollutants considered are: NO2, PM10, NOx, and Hazardous Air Pollutants (HAPs). The averaging periods are: 01H, 24H, MO, ANN for 1-hr, 24-hr, monthly, or annual, respectively. Either the first, second, third, etc highest value can be visualized, although not all possible values were available.
