    • W-4a: Measure the vertical motion within deep convection to within 1 m/s and heavy precipitation rates to within 1 mm/hour to improve model representation of extreme precipitation and to determine convective transport and redistribution of mass, moisture, momentum, and chemical species.

  • Traceability to Decadal Survey:
    • C-2a: Reduce uncertainty in low and high cloud feedback by a factor of 2.
    • C-2h: Reduce the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) total aerosol radiative forcing uncertainty by a factor of 2.
  • Objective 5: Aerosol Attribution and Air-Quality
  • Objective 6: Aerosol Redistribution
  • Traceability to Decadal Survey:
    • W-5a: Improve the understanding of the processes that determine air pollution distributions and aid estimation of global air pollution impacts on human health and ecosystems by reducing uncertainty to <10% of vertically-resolved tropospheric fields (including surface concentrations) of speciated particulate matter (PM), ozone (O3), and nitrogen dioxide (NO2).
  • Objective 7: Aerosol Direct Effect and Absorption
  • Objective 8: Aerosol Indirect Effect
  • Traceability to Decadal Survey:
    • C-2a: Reduce uncertainty in low and high cloud feedback by a factor of 2.
