Parametric Sensitivity of Hemispheric Albedo Symmetry Weakly Constrains Shortwave Cloud Radiative Feedbacks in the Community Atmosphere Model Version 6 Open
Earth's albedo is symmetric between the northern and southern hemispheres (NH and SH, respectively) because SH clouds compensate for higher NH clear‐sky albedo, a feature that climate models have difficulty capturing. We assess how paramet…

Fluorescent primary bioaerosol particle measurements in mixed phase cloud residuals at Mount Helmos, Greece Open
The partitioning between liquid- and ice-phase cloud water content can have a substantial impact on the cloud’s radiative effect and on precipitation. This partitioning is expected to change on average with global warming due to warm…

The implications of maintaining Earth's hemispheric albedo symmetry for shortwave radiative feedbacks Open
The Earth's albedo is observed to be symmetric between the hemispheres on the annual mean timescale, despite the clear-sky albedo being asymmetrically higher in the Northern Hemisphere due to more land area and aerosol sources; this is bec…
