Brief description

Atmospheric aerosols were continuously sampled on the RV Investigator during the cold water trial (IN2015_E01) in January to February 2015. The ship travelled from Hobart, Australia to the Antarctic ice edge before returning to Hobart. This was a trial voyage of the newly commissioned RV Investigator, and there was some loss of spatial, meteorological and gas-phase data due to faults in the ship’s instrumentation suite.
Within the suite of observations included observations of number concentrations of aerosols (condensation nuclei larger than 10 nm, CN10, using a TSI Condensation Particle Counter 3772) and cloud condensation nuclei (CCN, measured using a DMT CCN-100).

Sampling periods impacted by faults or maintenance associated with the aerosol instrumentation 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.
Supporting measurements of gas species, black carbon mass concentrations and local meteorology have been averaged to the same time-base (5 min) to assist with identification of samples contaminated by ship emissions.
The ”summary” document provides further details of the records available, sampling parameters and data analysis applied to this dataset.
