Size-resolved Physicochemical Properties of Biomass Burning Aerosol

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

ManishKumar Shrivastava

Project type

Exploratory Research

Biomass burning aerosol (BBA) is a major component of atmospheric aerosols and plays critical roles in the climate. BBA can affect climate directly by absorbing and scattering light, causing overall…

Development of Atmospheric Pressure Environmental (APE) Chamber for Chemical Imaging of Aerosol, Plant, and Soil Samples

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Zezhen Cheng

Maintaining low-pressure (∼2×10−6-10 Torr) inside the Environmental Scanning Electron Microscope (ESEM) chamber is the major challenge in pressure- and/or relative humidity (RH)-sensitive sample (e.g…

Development of an automated volatile organic compounds sampling system

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Swarup China

Volatile organic compounds (VOCs, released from plants, soil and leaf litter) are important precursors of ozone and secondary organic aerosols. Gaps in observations of vertically-resolved, chemically…

Algae from Ocean to Atmosphere: Exploring Coastal Ecosystems and Their Impact on Health, Climate, And Precipitation

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Michaela Rogers

Marine species undergo biogeochemical cycles which yield highly dynamic composition at the ocean interface and air environment. With uncertainty in ocean and atmosphere composition, experimental…

Development of a controlled combustion system for atmospheric and ecological studies

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

Zezhen Cheng

Combustion carbonaceous aerosols (CCA) have important but poorly constrained climatic and ecosystem effects due to real-life combustion's chaotic nature, which leads to the generation of…

Development of size and time-resolved automated aerosol sampler for unmanned aerial systems

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Swarup China

Project type

Scientific Partner

The radiative forcing of the ambient aerosol is strongly influenced by the vertical distribution of aerosols and their chemical composition, and not well constrained in climate models. Both satellite…
