WINTER 2015

Wintertime INvestigation of Transport, Emissions, and Reactivity


In February- March 2015, we took part in a cooperative aircraft campaign with collaborators from NOAA’s Earth System Research Laboratory, UC Berkley, Georgia Institute of Technology, University of Colorado, and the University of New Hampshire. The campaign will focus on wintertime emissions and chemical processes in the Northeastern US. The project has three goals:

(1) to characterize the chemical transformations of wintertime emissions with an equal focus on nocturnal and multiphase processes as on photochemistry;

(2) to assess the dominant mechanism of secondary aerosol formation and quantify the geographical distribution of inorganic and organic aerosol types during winter;

(3) to provide constraints on wintertime emission inventories for urban areas, power plants and agricultural areas, and characterize the export pathways of primary pollutants to the North Atlantic.

The NSF-NCAR C-130 aircraft

WINTER will use the NSF/NCAR C-130 aircraft based at NASA Langley in Hampton, VA to address these goals. The C-130 is proposed to be outfitted with over 15 instruments, including our HR-ToF-CIMS, to measure NOx, HOx, SO2, NH3, VOCs, aerosol size and composition, inorganic acids, and important chlorine reservoirs.These measurements will be made in large urban and industrial plumes, coal-fired power plant emission and distributed emissions from oil and gas extraction, agricultural or biofuel burning, and vegetation in the mid-Atlantic and southeast U.S.
