ASCENT – Atmospheric Science and Chemistry mEasurement NeTwork

ASCENT logo - aerosols under the horizontal bar in a capital A where the bar extends to look like a negative parabola The Atmospheric Science and Chemistry mEasurement Network (ASCENT) is a collaboration between 12 schools funded by the NSF intended to provide long-term and high-time-resolution aerosol data from across the country. This will help determine the composition, abundance, and properties of aerosols which are known to impact both human health and climate change. Each site will have four instruments: the aerosol chemical speciation monitor (ACSM), Xact (continuous ambient multi-metals monitor), Aethalometer (measures black and brown carbon), and scanning mobility particle sizer (SMPS – measures aerosol concentration and size distribution). Specifically, the UW field site is located near Cape Flattery at Cheeka Peak and is designated as a clean marine background site. Funding start on October 1, 2021 with an estimated end on September 30, 2024.

NSF Mid-Scale Research Infrastructure program

Scientific objectives

  1. To provide the first high time-resolution, long-term measurements of the properties of atmospheric particulates
  2. To determine how the composition and abundance of aerosols are changing

AGENA – Aerosol Growth in the Eastern North Atlantic

The logo for AGENA (Aerosol Growth in the Eastern North Atlantic) depicting red aerosols getting larger in the air as it gets closer to two islands in the water. AGENA campaign took place 1 June – 15 July 2022 at the US Department of Energy ARM Eastern North Atlantic (ENA) station. ENA is located on Graciosa Island, Azores, and is a permanent atmospheric radiation observatory. In collaboration with University of Wisconsin – Madison, Washington University in St. Louis and Stockholm University, we deployed an array of instrumentation to resolve the physical and chemical properties of aerosol particles over remote marine atmosphere. Specifically, the aim was to understand the chemical composition of oceanic emissions and which of the compounds are growing aerosol particles in this environment.

Funders

U.S. Department of Energy
Swedish Research Council

Scientific objectives

  1. To speciate marine reactive gases and their oxidation products
  2. To characterize particle growth in the marine boundary layer
  3. To harmonize estimates of CCN chemical composition
