1 Whole Atmosphere Community Climate Model (WACCM) and Its Thermosphere/Ionosphere Extension (WACCM-X) WAWG Co-Chairs: Han-Li Liu, NCAR/HAO Lorenzo Polvani, Columbia University
2 Scientific Objectives of WACCM Solar impacts on the Earth System. Understand and quantify couplings between atmospheric layers through chemical, physical and dynamical processes. Implications of the couplings to climate (downward coupling) and to near space environment (upward coupling).
3 CESM Atmosphere Components HAO/ACD/CGD WACCMX is WACCM with additional physics and further upward extended vertical range through thermosphere/ionosphere (~500km) ACD/CGD Whole Atmosphere Community Climate Model (WACCM) is CAM with additional chemistry/physics and upward extended vertical range into lower thermosphere/ionosphere (~140km) CGD Community Atmosphere Model (CAM) is atmospheric component of CESM NCAR CGD Community Earth System Model (CESM)

CCMI: ozone depletion and recovery trend. SOLARIS: Sensitivity to solar spectral irradiance. APSiC: Stratosphere aerosals and climate Geo-engineering: GeoMIP. Large-ensemble runs ( ). Paleoclimate runs (last Millennium).

13 System Coupling (and associated biases) Possible role of middle atmosphere on regional climate. Turbulent mountain stress (TMS) and statistics of SSW and troposphere blocking. Heating/cooling caused by volcano eruption. Absence/bias in resolving QBO. Cold pole bias in the polar stratosphere (especially SH). Bias in mesopause/lower thermosphere temperature and winds: mean structure, variability and tides. Thermosphere/ionosphere variability: ENSO, QBO, SSW/planetary waves, and day-to-day scales.
