  • This record describes atmospheric greenhouse data collected by a Cavity Ring-Down Spectroscopy (CRDS) analyzer (Picarro G2301, PICARRO Inc., USA) collected on RV Investigator voyage IN2015_E05. This is a trial voyage involving Geoscience, testing equipment and developing procedures, departing Hobart on the 1st May 2015 and returning to Hobart on the 5th May 2015. The Picarro G2301 atmospheric trace gas analyzer measures carbon dioxide (CO2), methane (CH4) and water (H2O) vapour in air. The analyzer is a wavelength-scanned laser-based CRDS spectrometer. The principle of operation and specifications can be found in the manufacturer's documentation link below.

  • This record describes the atmospheric greenhouse data acquired by a continuous wave Quantum Cascading Laser (QCL) analyser (QC-TILDAS, Aerodyne Research Inc., USA) collected on the Marine National Facility RV Investigator Event voyage IN2015_E01. This is a trial voyage for the RV Investigator departing Hobart on the 29 Jan 2015 and returning to Hobart on the 19 Feb 2015. It is an atmospheric greenhouse gas analyser for measuring nitrous oxide, carbon monoxide and water vapour in air. This instrument is an MNF procurement. The air is partially dried with a refrigerated dryer (5oC) to avoid potential condensation in the sample lines, valve and instrument. Measurements are extrapolated to dry air mole fractions. Calibrations are conducted pre and post each voyage and at a monthly interval for extended voyages. Calibrations are conducted in-situ with three calibrated air standards. An automated daily reference gas sample is also conducted (15 minutes).

  • This record describes the data collected on the RV Investigator Voyage IN2016_V05 Titled: "The Great Barrier Reef as a significant source of climatically relevant aerosol particles." The voyage took place between September 26 and October 24, 2016 departing from Brisbane (QLD) and arriving in Brisbane. Instrument Name: Microtops II Ozone Monitor- Sunphotometer, ECN # 2624374, is a hand-held multi-band sunphotometer capable of measuring the total ozone column and optionally the water vapor column (also called precipitable water) as well as aerosol optical thickness at 1020nm. Parameters measured: AOD (Aerosol Optical Depth). Data format: .xls, Owner of instrument: NASA. Further Information can be found in the data and documentation links below.
