ACE-1: R/V Discoverer Impactor (2-stage) Data

Summary

This dataset consists of 2-stage Impactor Data collected aboard the R/V Discoverer by P. Quinn (NOAA/PMEL) during ACE-1. Ion concentrations are given in ng/m3. Submicron values represent the ion concentration in all particles with aerodynamic diameters < 1.0 microns. Super micron values are for particles with aerodynamic diameters > 1 micron and < 10 microns. Diameters are given for the relative humidity of the sampled air stream. These diameters are given for a flow rate of 30 lpm and are subject to change after calibration of the collection efficiency of the impactor jet plate. This calibration is planned for the Fall, 1996. Uncertainties associated with the ion concentrations range from +/- 5 to 25%. Please refer to the "readme" file for a complete list of parameters and ions in this dataset.
