The ability to further improve the predictability of climate change and its associated impacts depends on improving our understanding of how aerosols and clouds influence Earth’s energy budget. The magnitudes of these impacts are determined by the evolution of aerosol and cloud properties and are driven by processes operating over a wide range of spatial and temporal scales. A deeper understanding of the processes that drive aerosol and cloud lifecycles is therefore critical for improving representation of aerosol-cloud-climate forcing and feedback in large-scale models and reducing outstanding uncertainties. Towards achieving this deeper understanding, the Process-level AdvancementS of Climate through Cloud and Aerosol Lifecycle Studies (PASCCALS) Science Plan guides the activities of the research team from Brookhaven National Laboratory and Argonne National Laboratory to advance process-level understanding of aerosol-cloud-radiation interactions to reduce associated uncertainties in determining climate forcings and feedbacks. The research is conducted within five interconnected themes: (1) Aerosol Formation, Growth and Contribution to Cloud Condensation Nuclei (CCN), (2) Reducing Uncertainty in Aerosol-Radiation Interactions: Biomass Burning Aerosols and Beyond, (3) Cloud Processes in the Atmospheric Boundary Layer, (4) Convective Cloud Dynamics and Microphysics and (5) Two-way Aerosol-Convection Interactions during the TRACER Campaign.
Aerosol Formation, Growth and Contribution to Cloud Condensation Nuclei – New particle formation (NPF) by nucleation of gas phase species significantly influences the size distributions and number concentrations of atmospheric aerosol particles. The fundamental understanding of the pathways for NPF to CCN remains mostly unknown. Since cloud droplet activation normally occurs on particles with diameters of 50 – 100 nm, the key to understanding the impact of NPF on climate lies in the ability to predict not only the rate of formation, but also the subsequent growth rates, of new particles. This research area focuses on developing the fundamental science of particle formation and growth and the representation of these processes in climate models where they are sub-grid scale and hence heavily parameterized. A key investigative focus of this activity is on determining the critical gas-phase precursors that drive NPF and improving understanding the spatial distribution and timing of NPF throughout the boundary layer.
Reducing Uncertainty in Aerosol-Radiation Interactions: Biomass Burning Aerosols and Beyond – Natural and anthropogenic aerosols perturb Earth’s energy balance by absorbing or scattering incoming solar radiation, altering cloud properties and precipitation behavior, and perturbing atmospheric circulation dynamics. While great strides have been made in uncovering the underlying processes that drive these effects, aerosol radiative forcing uncertainties from absorbing aerosols remain stubbornly high. This portion of the project focuses on reducing some of these uncertainties, with the main emphasis being on those involving biomass burning aerosols (BBA). We investigate aging processes of BBA properties that occur near-source and during long-range transport of BBA, and the interactions between BBA and clouds. Additionally, we will begin a new research direction in coarse mode aerosols, a class that poses challenges in characterization, that is generally under-sampled, and poorly represented in models. Because of their large size, coarse-mode aerosol particles can provide large contributions to aerosol direct effects in both shortwave and longwave, even with small number concentrations, and they can also serve as giant CCN and efficient ice nucleating particles.
Cloud Processes in the Atmospheric Boundary Layer – Recent Coupled Model Intercomparison Project 6 results indicate that the climate model sensitivity has increased from previous assessments with a statistically higher sensitivity range compared to previous assessments. This increase in climate model sensitivity resulted from shortwave low-cloud feedback, from model representations of marine boundary layer clouds and particularly extratropical mixed-phase clouds. These clouds systems are also strongly influenced by aerosol-cloud interactions, which yield the largest uncertainty in climate forcing. Aerosol-cloud interactions are strongly controlled by the vertical velocity of cloud-scale updrafts and entrainment in deep convective systems that lack needed observational constraints. In this project we address these challenges through process-level studies that combine unique retrieval and analysis capabilities with theory and modeling. With the maturity of these activities on different components of boundary layer cloud research during previous project cycles, we are now poised to start combining this accumulated understanding to form a holistic picture of the boundary layer processes.
Convective Cloud Dynamics and Microphysics – Convective clouds play an important role in the vertical transport of heat, moisture, momentum, and chemical species throughout the depth of the troposphere and provide an important driver for the large-scale atmospheric circulation. Additionally, convective clouds influence the atmospheric energy balance through diabatic heating, provide the primary contribution to precipitation and precipitation extremes, and remotely influence environments that determine lower cloud feedbacks to climate sensitivity. Despite the importance of these cloud systems, their accurate representation, at various scales, in atmospheric models remains a challenge. A key element that would improve simulation of these clouds is a better quantification and parameterization of convective updraft microphysics and dynamics, including their interaction with the surrounding environmental and with mesoscale storm organization.
Two-way Aerosol-Convection Interactions during the TRACER Campaign – To understand the two-way interaction of atmospheric aerosols and convection, particularly: (1) the potential role of aerosols in the invigoration of convective updrafts, (2) the associated influence on cloud areal coverage and precipitation amount, and (3) the subsequent feedbacks, through vertical transport, on the boundary layer population of aerosol particles and cloud condensation nuclei, we leverage the complementary expertise within the PASCCALS team to execute an integrated research approach using observations from the TRacking Aerosol Convection interactions ExpeRiment (TRACER) with contributions from aerosol and cloud scientists that includes observationalists, theoreticians, and modelers. Specifically, the team expertise will be aimed at:
- Determining the processes that drive the characteristics of the local aerosol population including the size, number, optical and chemical properties, and associated water-uptake;
- Quantifying the environmental drivers of convective cloud buoyancy, vertical velocity, entrainment and cloud lifecycle;
- Quantifying the microphysical impacts of variations in the number concentration of cloud condensation nuclei on convective precipitation formation; and
- Determining the feedback of the convective cloud system on the environment including the vertical transport of atmospheric aerosols.
The PASCCALS team employs a multi-scale approach with an emphasis on fundamental process scales that range from molecular scales to microphysical and eddy-resolving scales, to cloud-resolving scales, and finally to global scales. The objectives outlined in this science plan will be met by the PASCCALS science team and external partners by employing a combination of approaches including the analysis of data from the Atmospheric Radiation Measurement (ARM) user facility (fixed site, mobile facility and aerial facility) and external datasets, laboratory measurements, theoretical development, high-resolution modeling and large-scale modeling.
