The Atmospheric Science and Chemistry mEasurement NeTwork (ASCENT) is a new comprehensive, high-time-resolution, long-term measurement network in the U.S. for the characterization of aerosol chemical composition and physical properties. ASCENT is funded through the NSF Mid-Scale Research Infrastructure program. Read more »

How We Gather Data

Each ASCENT site is equipped with a suite of advanced aerosol instrumentation for real-time measurements of fine aerosol chemical composition and properties: 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).
