- 1 Intro
- 2 What is the origin of the Belterra Clay formation, one of the most abundant surface materials of the Amazon Basin?
- 3 Dust transport from Africa to Amazonia
- 4 Sampling sites
- 5 Major element composition: Bodélé vs. Belterra
- 6 Rare earth patterns differ strongly between Belterra and Bodélé
- 7 No overlap between Pb isotope sienatures of African dust and Belterra
- 8 Neodymium isotopes
- 9 Belterra isotopes inconsistent with rivers from Andes
- 10 Isotope systems can also elucidate source regions of dusts that do reach the western Atlantic and South America...
- 11 Conclusions
- 12 Measurements of African dust aerosol properties as ice nuclei in the laboratory and atmosphere
- 13 Overview of Presentation
- 14 Dust data during ICE-T stand out in comparison to global IN parameterization of size dependence
- 15 CFDC field and lab data are consistent for both African and Asian mineral dusts
- 16 ICE-TRF4 profile through African dust layer and Ke nuclei parameterizations
- 17 ICE-T RF6 ice nuclei concentration versus T
- 18 Aside: Seaspray IN (lab-red pts) ICE-T (blue pes) and historical marine IN data comparison
- 19 Acknowledgments
- 20 Does Precipitation Follow the Surface Forcing?
