Radiation, Air Quality, Weather Monitoring
and ADAPT Modeling Results

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.
