- 1 Intro
- 2 Small aerosols, big health impact!
- 3 New-particle formation (NPF) is the most important source of aerosols
- 4 Complicated formation chemistry of secondary organic aerosol (SOA)
- 5 Aerosols have potentially important but highly uncertain impact on climate
- 6 How to represent organic NPF in models?
- 7 Development of NPF schemes within regional and global models
- 8 The new WRF-Chem model improves particle number simulations over the Amazon
- 9 NPF mechanisms over the Amazon
- 10 Global modeling using our new E3SM model show similar results over the Amazon
- 11 Contribution of NPF to CCN over the Amazon
- 12 The new E3SM model improves simulations of particle size distribution in eastern China
- 13 Amine+H,SO, is the dominant NPF mechanism near the surface of eastern China
- 14 NPF mechanisms all over the world
- 15 SOA model scheme based on the 2D-VBS
- 16 Novel organic emission inventory (EI) covering the entire volatility range
- 17 The new model and inventory improve the Simulations of OA and SOA
- 18 IVOC is the largest source of SOA in China
- 19 VCPs, domestic combustion, and biomass open burning are top SOA contributors
- 20 Ice crystal size (R.)-aerosol relations modulated by convective strength
- 21 WRF-spectral-bin simulations show the key role of ice nucleating particles (INPS)
- 22 Observations and modeling indicate polluted continental aerosols contain a fraction of INPS
- 23 Response of the optical depth of different cloud types to aerosols
- 24 Response of deep convective precipitation to different aerosol types
- 25 How do we start to understand soil carbon turnover?
- 26 Trees, too, have the property that most of the carbon is in the oldest pools, particularly in tropical forests
- 27 Because most of the carbon on Earth is in the tails, we need to focus on what governs the dynamics there
- 28 Land carbon cycle feedbacks are a crucial and poorly quantified determinant of the Earth system response to CO, emissions
- 29 Isolate temperature from moisture effects by ignoring gridcells that are either too wet or too dry
- 30 A simple scaling theory for why temperature Sensitivity is high in cold climates
- 31 Vertical mixing by cryoturbation modeled as diffusive transport
- 32 Prajected sail Cemissions follow the retreating permafrost boundary and persist long after permafrast has thawed
- 33 What happens to trees if they grow taster because of elevated CO? And how sensitive is the answer to whether the causes of large-tree mortality have more to do with size versus age?
- 34 Basal area and aboveground biomass both Increase in response to elevated productivity but change is 50% smaller with size-driven large-tree mortality
- 35 10% reduction in woody biomass carbon turnover time in size- dependent mortality case
- 36 And observations show that mortality rates are already increasing alongside productivity in the Amazon
- 37 Conclusions
