  27. Conclusions • We can use this data to better understand our emission sources • Using a suite of continuous monitors (FDMS, nephelometer, aethalometer, etc) is essential to enriching the understanding of the data • Rich data sets currently available • Continuous monitors like the Aethalometer can provide: • Real-time data • Cheaper sampling • More data • Currently packaged in a few of our publicly available products
