  1. Chemistry of Aerosols Analyzing the composition of aerosols collected on Mt. Pico Photo: L. Harkness

  2. Describe how the high volume sampler works. • Write observations of the filters. Video Notes:

  3. Video: Collecting Aerosols with the samplers Click here for the video!! Video: L. Harkness

  4. Describe how instruments and filters are prepared. • How does the OC/EC work? • What do the colored lines on the screen represent? Video Notes:

  5. Video: Analyzing Filter Samples for Carbon Click here for the video!! Video: L. Harkness

  6. Analyze graphs of OC data from various dates • Research the weather that day and previous 5 days • From which land mass could the aerosols have come from? • Research any possible events that would cause high levels of organic aerosols around that date. Today’s Tasks:

  7. www.wunderground.com Search “Pico, Portugal” History – go to day of event and the days prior; look at wind direction • http://fires.globalincidentmap.com/home.php Put in date range and check for fires in North America Sites to use:

  8. Global Atmospheric Circulation http://www.lsrhs.net/departments/science/faculty/brandesa/images/winds.jpg

  9. Examples of Data: Graph provided by: S. Schum

  10. Examples of Data: Graph provided by: S. Schum

  11. The difference between an event and a non-event is the amount of carbon in micrograms per cubic meter • OC (organic carbon): soot, carbon from life sources (decomposition, trees – oils, burning, marine organisms) • EC (elemental carbon): similar to graphite Examples of Data:
