Abstract: Plasmaspheric rotation is known to lag behind Earth rotation. The causes for this corotation lag are not yet fully understood. We have used more than two years of Van Allen Probe observations to compare the… read more here.

DOI: 10.1002/qj.4979
Abstract: In this work we show how to extend the deterministic physical nudging scheme in order to include two important ingredients, the model and observation‐error covariance matrices, which are common features of classical data‐assimilation schemes. The… read more here.

DOI: 10.1088/1748-9326/ab858e
Abstract: Over the 20th and 21st centuries, both anthropogenic greenhouse gas increases and changes in anthropogenic aerosols have affected rainfall in the Sahel. Using multiple characteristics of Sahel precipitation, we construct a multivariate fingerprint that allows… read more here.
