Evidence for an oceanic source of methyl ethyl ketone to the atmosphere
Methyl ethyl ketone (MEK) is a relatively abundant but understudied oxygenated volatile organic compound that can serve as a source of both HOx and PAN when photooxidized. We...- publication PDF

Climate, CO₂ and human population impacts on global wildfire emissions
Wildfires are by far the largest contributor to global biomass burning and constitute a large global source of atmospheric traces gases and aerosols. Such emissions have a...- publication PDF

A self-consistent model of helium in the thermosphere
We have found that consideration of neutral helium as a major species leads to a more complete physics-based modeling description of the Earth's upper thermosphere. An augmented...- publication PDF
