Non-refractory PM2.5 Composition from ASCENT The ASCENT Team CALTECH/EAS > Division of Engineering and Applied Science, California Institute of Technology NSF National Center for Atmospheric Research Published: 2025-09-26 Valid: 2022-07-01 to 2026-08-31 climatologyMeteorologyAtmosphere In this dataset, non-refractory composition of PM2.5 measured by an Aerosol Chemical Speciation Monitor (ACSM, Aerodyne Research Inc.) is reported. The measurements are reported at 10 minute intervals. The ACSM is equipped with a PM2.5 aerodynamic lens, a standard vaporizer, and a time-of-flight mass spectrometer.
