3. Scientific Challenge: Description of PM Gaseous concentration: g (X, Y, Z, T) Aerosol concentration: a (X, Y, Z, T, D, C, F, M) The ‘aerosol dimensions’ size D, composition C, shape F, and mixing M determine the impact on health, and welfare. DimensionAbbr. Data Sources Spatial dimensionsX, YSatellites, dense networks HeightZLidar, soundings TimeTContinuous monitoring Particle sizeDSize-segregated sampling Particle CompositionCSpeciated analysis Particle Shape/FormFMicroscopy Ext/Internal MixtureMMicroscopy Particulate matter is complex because of its multi-dimensionality It takes at leas 8 independent dimensions to describe the PM concentration pattern

4. Satellite Data Issue: Bright Surface (Cloud, Snow, Desert) Aerosol data are not retrievable over bright surfaces Thus half or more of the data are unavailable (some could be the most significant The data loss from clouds is sporadic, unpredictable

6. Vertical Distribution Aerosol Windblown Dust (crustal elements) Biomass Smoke (organics, H 2 0 ) Sea H 2 0 salt (NaCl. H 2 0) Stratospheric (Volcanic) (H2SO4) Biogenic (Non-sea salt sulfate, org) Urban-Industrial Haze (SO4, org. H 2 0) Dust, smoke, volcanic aerosol and industrial haze originate from land The global aerosol concentration is highest over land and near the continents over the oceans (coastal regions) Sea salt is significant over some of the windy oceanic regions and biogenic sulfate and organic aerosols also occur …

7. July 2020 Quebec Smoke Event Superposition of ASOS visibility data (NWS) and SeaWiFS reflectance data for July 7, 2002 – PM2.5 time series for New England sites. Note the high values at White Face Mtn. Micropulse Lidar data for July 6 and July 7, 2002 - intense smoke layer over D.C. at 2km altitude.

8. Remote sensing of Aerosol Open questions: - Where does aerosol begin and cloud ends? - Does aerosol in cloud free area represent the aerosol that interacts with clouds? - How to handle the spatial and temporal variability of aerosol properties? Haze layer Clean atmosphere Y. Kaufman, 2002

14. Question to Class Participants: (Exam!  ) How do YOU see the incorporation of satellite data into your activities? –Describe context: (what kind of AQ-related activity) –What problem could use satellite data? Specific satellite? Region of interest? Data ‘products? Delivery (frequency, latency, –What tools you whish you had for satellites? Assess and viewing/prowsing? Processing? –Add and answer your own question (The quality of your question will determine your final grade)
