1 Atmospheric Aerosols in Amazonia and land use change: from natural biogenic to biomass burning conditions Keith Heidecorn Graduate Seminar in Atmospheric Sciences April 7, 2014

2 1. Learn Something New 2. Observe the Effect of the Dry & Wet Season on Land Types 3. Gain Insight into how Aerosols Effect more than just the Atmosphere Goals

3 Aerosol Optical Depth Black Carbon Single Scattering Albedo Net Ecosystem Exchange (NEE) Definitions

8 Wet Season is from January to June Dry Season is from July to December Which Season would you expect more Land Use Change? Wet vs. Dry Season

9 Deforestation

10 Instrumentation TSI-3080 SMPS TSI CPC MODEL 3010 MODIS SATELLITE

11 Mass Concentrations of the Sites Why?

12 Black Carbon

13 Median Aerosol Number Size Distributions DOES SIZE MATTER?YES

14 Submicron Non Refractory Aerosol Composition PVH SITE TT34 SITE WHY DIFFERENT?

15 Median Scattering & Absorption Coefficients

16 550 nm 637 nm WET DRY

17 Aerosol Optical Depths (AOD) ARE THE PEAKS DURING THE DRY OR WET SEASON? DRY

18 Monthly Ozone

19 Daily Ozone

20 Carbon Monoxide

21 Net Ecosystem Exchange (NEE)

23 Complexity of the Problem Land Use Change has Altered Multiple Systems Insights from an Interdisciplinary Approach What Have We Learned

24 Why Should We Care?
