<p class="MsoNormal" style="margin: 0in; line-height: normal; font-size: medium;">
</p>
<div style="margin: 0in; line-height: normal; font-size: medium;">ABSTRACT: Earth’s climate is, to first order, determined by the balance of incoming solar radiation and outgoing infrared radiation. I will focus on the shortwave, where clouds and aerosols are
fundamental in setting the planetary albedo. However, the processes that control the distribution of clouds and the albedo of the clouds themselves span a dozen orders of magnitude in scale, from aerosol activation (micrometers), to boundary layer turbulence
(meters), up to the global distribution of cloud regimes set by the large-scale atmospheric circulation (100s of kilometers). My work spans a wide range of topics, where the aim is to understand how clouds radiatively shape climate and climate changes. To
tackle this range of scales, I use a similarly wide range of models and observations that are each fit for purpose. In this talk I will highlight three examples from my work that fill in this hierarchy of scales and process complexity. <br>
<br>
Starting at the global scale, I will discuss the recent observed trend of decreased global reflectivity and its hemispheric asymmetry and show that an important contribution to this has been an increase in sea spray aerosol emission over the Southern Ocean.
Jumping to smaller scales, I will give an example of how we can build a conceptual model of boundary layer clouds to explore the robustness and sensitivity of CO2-induced stratocumulus cloud breakup. I will discuss the connection to climatological cloud regime
transitions, cloud feedbacks, and proposed future deliberate cloud interventions. Finally, at the very smallest scales, I will show how we can use a new class of particle-based cloud microphysical models to bridge from novel laboratory measurements of secondary
organic aerosol to climate-relevant impacts on cloud albedo. Lastly, I will conclude with a discussion of my future research directions.<o:p></o:p></div>
