HaloxComp Antarctic instrumentation receives final testing and validation at the Centre for Research into Atmospheric Chemistry
The HaloxComp campaign is a series of experiments involving researchers from France, China, India, and the ERI.
The aim of the measurements is to test and validate instrumentation before deployment this upcoming austral summer at the French Antarctic stations Dumont d'Urville and Concordia. The instruments, from the University of Grenoble, are exquisitely sensitive to iodine and bromine oxides. Measuring the concentrations of these species is critical to understand the fate of ozone and mercury in the fragile polar environment.
However, these are tricky and highly reactive compounds – and validating their measurement is technically challenging. Fortunately, the Centre for Research into Atmospheric Chemistry has a unique combination of atmospheric simulation chamber facilities and expertise in advanced spectroscopic methods. This combination makes the ERI facilities an ideal testbed for these instruments. The HaloxComp campaign, which is supported by the Eurochamp2020 project, will also explore the reactions of iodine and nitrogen oxides in the atmosphere. Researchers from India and China will assist in the development of multiple custom spectrometers and data analysis for the measurements.
The campaign participants are Roberto Grilli, Albane Barbero, and Camille Blouzon (University of Grenoble); Meng Wang and Jun Chen (University of Shanghai of Science and Technology); Anoop Sreevalsam and Arun Ramachandran (National Institute of Technology Calicut); and ERI researchers Brian Keary and Andy Ruth (Physics), and Dean Venables (Chemistry)
