This value-added product (VAP) corrects aerosol chemical speciation monitor (ACSM) data for non-unity particle detection. The VAP is based on a procedure described in Middlebrook et al. (2012). The procedure applies the Middlebrook composition-dependent collection efficiency (CDCE) correction to the ACSM data to improve their accuracy, and it brings the data into better agreement with other co-located aerosol measurements.
