Aerosol Properties, Ice-edge to Equator voyage (IN2016_V03): CN3 and CCN
Atmospheric aerosols were continuously sampled on the RV Investigator during the Ice-edge to Equator (I2E) voyage (IN2016_V03) between April and June 2016. The ship travelled from Hobart, Australia to the Ross Sea and then along the 170th west meridian to the equator, before traversing to Lautoka, F...

| Summary: | Atmospheric aerosols were continuously sampled on the RV Investigator during the Ice-edge to Equator (I2E) voyage (IN2016_V03) between April and June 2016. The ship travelled from Hobart, Australia to the Ross Sea and then along the 170th west meridian to the equator, before traversing to Lautoka, Fiji. Samples were drawn from an inlet mounted at the bow, approximately 18 m above sea level.\n\nWithin the suite of observations included observations of number concentrations of aerosols (condensation nuclei larger than 3 nm, CN3, using a TSI Condensation Particle Counter 3776) and cloud condensation nuclei (CCN, measured using a DMT CCN-100).\n\nSupporting measurements of gas species, black carbon mass concentrations and local meteorology have been averaged to the same time-base to assist with identification of samples contaminated by ship emissions.\n\nSampling periods impacted by instrument faults or maintenance were logged and have been identified with a “log_flag”. Sampling periods that showed evidence of contamination from ship emissions have been identified with an “ex_flag”. Both flags are recorded in the in the “ProcessedAerosolData“ data file and further details are given in the “summary” file.\nThe ”summary” document provides further details of the records available, sampling parameters and data analysis applied to this dataset.\n |
