STI worked with the Delaware Department of Natural Resources and Environmental Control (DNREC) to analyze the transport of ozone concentrations into and throughout the state and to determine if the transport patterns observed in 2011 were representative of other years. STI also used the R code modeling platform to perform a detailed analysis of the ultrafine particle concentration data collected by the DNREC. After assessing the particle count data, STI trained DNREC staff through a series of webinars on the use of the R software for air quality data analysis.
