Exposure to PM\u003Csub\u003E2.5\u003C\/sub\u003E has been associated with cardiopulmonary diseases and millions of deaths per year.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026ldquo;ASCENT\u0026#39;s long-term, advanced chemical composition and particle size measurements will facilitate transformative studies to unravel specific aerosol types and properties responsible for their adverse health effects,\u0026rdquo; Ng said. \u0026ldquo;This will contribute to building a foundation to define future regulations in the U.S. for protecting public health, as aerosol sources and properties continue to evolve in a changing world.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAerosols impact climate by changing the Earth\u0026rsquo;s energy balance via direct absorption or scattering of solar radiation and altering the albedo (surface reflection), formation of clouds, and precipitation. The Intergovernmental Panel on Climate Change assessment established that the aerosol effects represent the single largest source of uncertainty in understanding climate change.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAccording to NSF, ASCENT will also allow U.S. researchers to remain competitive in a global research environment. The 2016 National Academies report on \u003Cem\u003EThe Future of Atmospheric Chemistry Research\u003C\/em\u003E emphasized the critical need for long-term atmospheric chemistry measurements, recommending that the NSF take the lead to establish synergies with existing sites.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ECurrently, several aerosol monitoring networks exist in the United States, but none have the capability of measuring aerosol chemical and physical properties at high time-resolution (highly regular intervals of measurement, in the order of minutes).\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe ASCENT network\u0026rsquo;s 12 sites across the United States are strategically located in rural, urban, and remote sites that have pre-existing infrastructure for atmospheric monitoring. Five ASCENT sites are in the National Core Network (NCore), which is a subset of the Chemical Speciation Network (CSN). Four rural sites are in the Interagency Monitoring of PROtected Visual Environment (IMPROVE) network. Other ASCENT sites are located in NSF\u0026rsquo;s National Ecological Observatory Network (NEON), the South Coast Air Quality Management District (AQMD) in California, and the Houston Network of Environmental Towers (HNET) in Texas.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EEach site will be equipped with four advanced instruments: an Aerosol Chemical Speciation Monitor (ACSM, non-refractory aerosols), Xact (trace metals), Aethalometer (black\/brown carbon), and Scanning Mobility Particle Sizer (SMPS, aerosol number size distribution and concentration).\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe sites include: Delta Junction, Alaska; Cheeka Peak\/Makah, Washington; Los Angeles\/Pico Rivera, California; Rubidoux, California; Joshua Tree National Park, California; Yellowstone National Park, Wyoming; Denver, Colorado; Houston, Texas; Pittsburgh, Pennsylvania; New York City; Atlanta, Georgia; and Great Smoky Mountain National Park, Tennessee.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EOn the education and outreach side of the project, ASCENT has specific recruitment, mentoring, training, and career development plans for graduate and undergraduate students, with an emphasis on underrepresented groups. One of the ASCENT locations is on tribal land and the project will train tribal air quality staff and perform outreach to interested tribal members. ASCENT will also provide training and educational opportunities for the state agency and National Park Service site operators.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn collaboration with the National
