Title: COAST‐k – Clean Ocean Air Sampling upwind of Tasmania ‐ kennaook
Period: 2025-04-28 22:00 to 2025-05-17 22:00 UTC
Duration: 19.00 days
From: Hobart To: Hobart
Ship: Investigator (RV) [details]
Description: The World Meteorological Organization’s (WMO) Global Atmosphere Watch (GAW) program consists of an observational network charged with understanding the increasing influence of human activity on the global atmosphere. The kennaook / Cape Grim Baseline Air Pollution Station (KCGBAPS), measuring the Southern Ocean’s atmosphere from the northwest tip of Tasmania, is one of three premier global GAW stations. By utilising the mobility of the RV Investigator (RVI), the world’s first mobile GAW station, both stations can be compared directly and data quality improved and validated. This high-quality observational data feeds directly into improving both regional and global climate, air quality and Earth System models. This project aims to: 1. Directly compare two world-leading WMO-GAW stations, the RVI and the KCGBAPS – a global first. This will include validating the RVI’s full suite of atmospheric measurements and sampling systems against complementary measurements at the KCGBAPS, improving data quality for all locations visited by the vessel. 2. Validate how representative measurements of atmospheric composition and boundary layer structure at the KCGBAPS is of the broader Southern Ocean. 3. Provide improved characterisation of atmospheric structure and composition to inform and improve earth system, climate, air quality and smoke forecasting models. 4. Determine the best boundary conditions for air quality modelling over Australia by improving our understanding of Southern Ocean and Cape Grim baseline concentrations of a range of trace atmospheric constituents.
