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
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
Aerosol Optical Depth Black Carbon Single Scattering Albedo Net Ecosystem Exchange (NEE) Definitions
TT34 (Central Amazon)PVH (Southern Amazon)
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
Instrumentation TSI-3080 SMPS TSI CPC MODEL 3010 MODIS SATELLITE
Mass Concentrations of the Sites Why?
Median Aerosol Number Size Distributions DOES SIZE MATTER?YES
Submicron Non Refractory Aerosol Composition PVH SITE TT34 SITE WHY DIFFERENT?
Median Scattering & Absorption Coefficients
550 nm 637 nm WET DRY
Aerosol Optical Depths (AOD) ARE THE PEAKS DURING THE DRY OR WET SEASON? DRY
Net Ecosystem Exchange (NEE)

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