ACE-1: R/V Discoverer Impactor (7-stage) Data


This dataset consists of 7-stage Impactor Data collected aboard the R/V Discoverer by P. Quinn (NOAA/PMEL) during ACE-1. These data contain ion concentration in ng/m3 for each stage. Diameters for aerodynamic D50 (micron) and dlogDp are reported at the relative humidity of the sampled air stream. (These diameters are given for a flow rate of 23 lpm and are subject to change after calibration of the collection efficiency of each jet plate. This calibration is planned for Fall, 1996). Please refer to the "readme" file for a complete list of parameters and ions found in this dataset.
