COVID‐19 crisis reduces free tropospheric ozone across the Northern Hemisphere
Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8...- publication PDF

Driving solar giant cells through the self-organization of near-surface plumes
Global 3D simulations of solar giant-cell convection have provided significant insight into the processes which yield the Sun's observed differential rotation and cyclic dynamo...- publication PDF
