How Do Aerosols Impact The Climate System Over Space and Time?

What are the Regional costs & benefits of aerosol mitigation?

What sets the spatial pattern of climate change?

how can we use climate models to better plan for the future? 

Welcome to the Persad Aero-Climate Group! 

Our research centers on innovative application of numerical global climate modeling to understand the behavior and societal impacts of the physical climate system. The core of our work focuses on the role of particle aerosol emissions, the primary radiative forcing offset to greenhouse gases over the industrial era, in driving inter-regional differences in the magnitude and rate of climate change and in the emergence of heat and hydroclimate extremes. A growing branch of our research applies this understanding of climate physics and modeling to questions at the interface of climate and hydrology, with a goal of understanding the climate shifts most likely to stress water management in the Central and Western U.S. An overarching goal of the lab's work is to understand how climatic change is most likely to stress human systems and how better understanding of these climate stresses in decision-making contexts can improve societal outcomes.

Latest news and updates

We're hiring! Check out the job posting for our new 3-year NSF-funded Postdoc Position in Aerosols and Patterns of Climate Change starting ASAP, pref. before June 2023. Applications review starting March 1, 2023, but position is open until filled.


Postdocs interested in co-developing fellowship proposals in our lab are highly encouraged to contact Dr. Persad via email.


Below are some project areas that new group members will have the opportunity to engage with:

  • The influence of the evolving geographic distribution of global aerosol emissions on climate, air quality, and societal decision-making

  • Interactions between aerosol, greenhouse gases, and irrigation/agricultural land management in monsoon climates

  • Natural aerosols' influence in the paleoclimate record and their feedbacks with future climate change

  • Novel uses of climate data to improve Western U.S. water management
