Shown below are the most current graphic summaries from a real-time
Aware Electronics radiation
monitor, a particulate monitor by
PurpleAir and a Davis
Vantage View weather station. All instruments are co-located in the
Washington, D.C. suburbs. The meteorological source analysis was
done using the ADAPT model. The color filled regions represent the direction
of the source of the air measured by the various sensors for
each six hour period. The pollutant source and sensor plots are updated
four times per day. Only the last four updates are shown below. Click on
any of the column titles for more detailed descriptions. Click on any
image for an enlarged version of the graphic. Graphics from the last 31
days monitoring are available from the monthly archive.
