Below find links to the raw data used by the NetAssess App. All of these files are available on NetAssess's GitHub page and are included here as a convenience.
- netassess.sqlite
- An sqlite database that contains site and monitor records compiled from the "Site and Monitor Records" file available here. The file used in this version of NetAssess was dated 4/2/14. This database also contains daily concentration records for ozone and PM2.5 and yearly design values for all criteria pollutants acquired through EPA's AQS system.
- tracts.rda
- An rdata file that consists of a data.frame containing demographic data and the centroid for each 2010 census tract. These data are used to compile the area served statistics. It was taken from the U.S. Census Bureau as a shapefile and processed in R.
- usborder.rda
- An rdata file that contains a spatialPolygons object. This object is an outline of the United States and is used to clip the area served polygons at the US border. It was taken from the U.S. Census Bureau's Cartagraphic Boundary Shapefiles Page and then further simplified to speed up processing times.
- sites.geojson
- A geojson file that contains basic information about each monitoring site in the network. This file is built programmatically from the netassess.sqlite database when the app is started.
- pm25_35.png
- A png image depicting exceedence probability for PM2.5 based on a threshold of 35 μg/m3. Used as an overlay in the app. See the Tools section for more info about its creation.
- o3_75.png
- A png image depicting exceedence probability for Ozone based on a threshold of 0.075 ppm. Used as an overlay in the app. See the Tools section for more info about its creation.
- o3_70.png
- A png image depicting exceedence probability for Ozone based on a threshold of 0.070 ppm. Used as an overlay in the app. See the Tools section for more info about its creation.
- o3_65.png
- A png image depicting exceedence probability for Ozone based on a threshold of 0.065 ppm. Used as an overlay in the app. See the Tools section for more info about its creation.
