BNL Home

Environmental and Climate research at Brookhaven National Lab is focused on aerosol chemistry and microphysics, aerosol related infrastructure, climate and process modeling, cloud processes, data management and software engineering, terrestrial ecosystems, meteorological services, and tracer technologies.

Aerosol Chemistry & Microphysics

Focused on improving process-level understanding of aerosol formation and evolution mechanisms, aerosol absorption, and the direct and indirect influences that aerosols have on clouds, precipitation and climate.

Aerosol Related Infrastructure

Provides measurement capabilities to the DOE Atmospheric Radiation Measurement (ARM) program for long-term measurements of aerosols and their precursors across a global network of ground- and aircraft-based locations. 

Climate and Process Modeling

Uses multi-scale process modeling and observational analyses to understand the processes essential to clouds, precipitation, land-atmosphere interactions, and urban impacts.

Cloud Processes

Seeks to improve understanding of microphysical and dynamical processes that impact the lifecycle of clouds to improve their representation in climate models.

Technology Development & Applications and Meteorological Services

Responsible for the maintenance, calibration, data collection and data archiving for the weather instrumentation network associated with BNL's atmospheric dispersion concerns. 

Terrestrial Ecosystem Science & Technology

Seeks to improve the representation of ecosystem processes in Earth System Models in order to increase our ability to understand and project global change. 

Tracer Technologies

The Tracer Technology Group uses perfluorocarbon tracers as a tool for understanding the processes that transport air, heat, water, and pollutants.

    "Observational insight into the relationships between large-scale conditions and the properties of boundary-layer precipitation"

    Reanalysis and observations collected at ENA are analyzed to document the properties of rain and boundary layer clouds during general subsidence conditions and following cold front passages. Clouds in the wake of cold fronts exhibit on average a 10% higher propensity to precipitate and higher rain-to-cloud fraction than clouds found in general subsidence conditions. The identification of monotonic relationships between rain-to-cloud fraction with surface forcing and boundary layer stability parameters as well as between virga base height with stability and humidity measures further supports that large-scale conditions impact precipitation variability. That being said, these relationships are less clear than those established between cloud and rain properties suggesting that cloud macrophysics have a more direct impact on the properties of rain than the large-scale environment.
