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 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
