New Aerosol Chemical Speciation Monitor Data Product Now Available
A new data product from the Atmospheric Radiation Measurement (ARM) user facility corrects time-of-flight aerosol chemical speciation monitor (ToF-ACSM) data for non-unity particle detection. The ToF-ACSM provides a quantitative measurement of aerosol particle chemical composition for nonrefractory aerosol components. One well-known limitation to the accuracy of the ToF-ACSM data is in evaluating the fraction of…
