Influence of continental ice retreat on future global climate
Evidence from observations indicates a net loss of global land-based ice and a rise of global sea level. Other than sea level rise, it is not clear how this loss of land-based...- publication PDF

Volcanic radiative forcing from 1979 to 2015
Using volcanic sulfur dioxide emissions in an aerosol-climate model, we derive a time series of global-mean volcanic effective radiative forcing (ERF) from 1979 to 2015. For...- publication PDF

Obstacles to high-dimensional particle filtering
Particle filters are ensemble-based assimilation schemes that, unlike the ensemble Kalman filter, employ a fully nonlinear and non-Gaussian analysis step to compute the...- publication PDF

Climate-change-driven accelerated sea-level rise detected in the altimeter era
Using a 25-y time series of precision satellite altimeter data from TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3, we estimate the climate-change-driven acceleration of global...- publication PDF
