ROCIS Data Explorer


When participants use low cost particle monitors the biggest impressions are often the incidents or spikes that cause the highest readings... like burning, or just cooking.  Of course, it's important to recognize and reduce the frequency of these spikes. 

However, we see a tenfold difference in the median particle counts between LCMP (Low Cost Monitoring Program) sites, and in most homes, the spikes do not appear to contribute significantly to that difference.  

How can we help folks make sense of the data? In one week alone, the three Dylos particle monitors generate 60,000 data points for each site! The ROCIS team has developed several tools to support LCMP participants. How do outdoor particle counts influence indoor counts? Does it help to use a kitchen exhaust fan or to use a portable air purifier?

ROCIS Data Explorer

The ROCIS Data Explorer is one of our visualization tools that we use to display particle monitoring data to participants, for a given monitoring location.  There are two styles of graphical representation of the 15-minute averaged monitoring data.

The first, a stacked bar chart, shows each of the 3 monitors at a participant's location.  The data is displayed as a percentage of time that the air was within a given range; very poor, poor, fair, good, very good.  This scale directly corresponds to the proprietary scale developed by the Dylos Corporation who manufactures the DC1700 particle monitor. 

The second graphical representation in the ROCIS Data Explorer tool is a timeseries line graph.  This shows a scale of particle count over time, and color-codes the line of data to correspond to the given machine at a monitoring location.  There are various toggles for total displayed time, machines' data displayed, smoothing of data lines, and the scale of particle count.
