1. Importance of dust feedback on forcing estimates
Jean-François Lamarque (NCAR)
with A. Fiore (Lamont-Doherty), D. Shindell (Duke), and A. Conley (NCAR)

2. Experimental design
Fully coupled CESM1 (same as PDRMIP) with chemistry
Constant 2005 conditions
Long control (300+ years)
Long perturbation (200+ years)
Also with GFDL and NASA-GISS models
Simulations with and without US SO2 emissions, coupled and specified SSTs (to compute ERF)

4. Response in AOD to US SO2 emissions,
annual average

5. Response in AOD to US SO2 emissions,
annual average

6. Response in AOD to US SO2 emissions,
annual average

9. Scaled by 1.e3
