The drivers of active region outflows into the slow solar wind
Plasma outflows from the edges of active regions have been suggested as a possible source of the slow solar wind. Spectroscopic measurements show that these outflows have an...- publication PDF

Uncertain pathways to a future safe climate
Global climate change is often thought of as a steady and approximately predictable physical response to increasing forcings, which then requires commensurate adaptation. But...- publication PDF

Growth rates of freshly nucleated atmospheric particles in Atlanta
During the Atlanta ANARChE Study of July and August 2002, atmospheric aerosol size distributions from 3 to 2000 nm were measured continuously with 5-min resolution. Sulfuric...- publication PDF
