April 2019 Particulate Measures

In April we finally had enough sensors to decide that we could start sharing a monthly report. This will be mostly just numbers and graphs at first but we are hoping to eventually start sharing our insights into what might be the sources of these particulates. The above graph represents 640,000 data points from about 50 sensors. Not all the sensors were online for the whole month so we have produced an accompanying table for each location showing min, max, avg and count where count is the number of measurements recorded.
