On the mechanisms of rain formation in an idealized supercell storm
Deep convective storms produce raindrops through three mechanisms: condensation and coalescence growth of cloud liquid droplets (i.e., warm processes), melting of ice...- publication PDF

Chemical feedback from decreasing carbon monoxide emissions
Understanding changes in the burden and growth rate of atmospheric methane (CH4) has been the focus of several recent studies but still lacks scientific consensus. Here we...- publication PDF

Net radiative forcing and air quality responses to regional CO emission reductions
Carbon monoxide (CO) emissions influence global and regional air quality and global climate change by affecting atmospheric oxidants and secondary species. We simulate the...- publication PDF

Variability of stratospheric reactive nitrogen and ozone related to the QBO
The stratospheric quasi-biennial oscillation (QBO) dominates interannual variability of dynamical variables and trace constituents in the tropical stratosphere and provides a...- publication PDF
