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.

    "Broadband Radiometry during EarthCARE: An Improved Solar Radiance-to-Flux Conversion"

    Presented by Florian Tornow, Freie Universitat Berlin

    Hosted by: Mike Jensen

    Outgoing radiative fluxes at top-of-atmosphere (TOA) are driven by the interaction of clouds, aerosols, and radiation. The upcoming EarthCARE mission aims to improve our understanding of this interaction and compares shortwave (SW) and longwave TOA fluxes from (1) radiative transfer simulations – acting on cloud and aerosol properties retrieved from onboard active and passive instruments – with (2) flux estimates based on broadband radiometer (BBR) measured radiances over horizontal domains of 10x10 km. To improve BBR-based TOA SW flux estimates, this talk explores a new approach that incorporates additional parameters (cloud-top effective radius and cloud-topped water vapor) and produces significantly different flux estimates when compared against state-of-the-art methodology.
