Chemical Speciation Network

CSN is the Chemical Speciation Network for the EPA. It is a PM2.5 sampling network with sites located principally in urban areas. The AQRC manages the data produced from CSN. The data first goes through a data ingest process that is completed by AQRC data management staff who have advanced training in database programming and database management.  Then an AQRC data analyst will process the sampling and analytical data. The data analyst will use functions in our custom software package to calculate final results and post them to the CSN database.


Interagency Monitoring of Protected Visual Environments

Nothing can ruin a visitor’s experience of a national park more than a blanket of haze. Not only does air pollution spoil the views that people travel hundreds or even thousands of miles to see, it also disrupts the natural environments that national parks and monuments were designed to preserve, while causing and contributing to a host of health problems for humans and wildlife alike.
