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).
