An atmospheric scientist in the School of Physical & Chemical Sciences at Te Whare W膩nanga o Waitaha | 蜜桃儿直播 (UC), Dr Revell is renowned for her expertise in chemistry-climate interactions and has made significant strides in understanding how the ozone layer is impacted by human activities, including from greenhouse gas emissions and an increased frequency of rocket launches.听
Her appointment to the IO3C for the 2024-2028 term, announced at the recent Quadrennial Ozone Symposium in Boulder, Colorado, marks a notable achievement for Aotearoa New 蜜桃儿直播鈥檚 wider scientific community. Dr Revell is the only New 蜜桃儿直播 representative on the IO3C for this term, underscoring her prominence in the field.听
Founded in 1948, the IO3C is a key organisation in coordinating global efforts to study the ozone layer through ground-based and satellite measurements. This role is vital for protecting Earth from harmful ultraviolet radiation and understanding its effects on the climate system.听
鈥淒espite the success of the Montreal Protocol in banning ozone-depleting chemicals such as CFCs, we鈥檙e entering an unusual era in which lots of factors could act to slow down ozone recovery,鈥 Dr Revell says.听
鈥淩ecently we鈥檝e seen massive wildfires in Australia contribute to depletion of the ozone layer over the Southern Hemisphere, along with effects from volcanic eruptions. Together with the ways in which humans are changing the composition of the atmosphere 鈥 such as greenhouse gas emissions, rocket launches, and global discussion of 鈥榞eoengineering鈥 methods to offset climate change 鈥 it is still critical that we pay attention to protection of the ozone layer.听
鈥淚n the last four years alone we鈥檝e seen unusual behaviour in the Antarctic ozone hole, with it closing much later in the year than normal, and potentially impacting Antarctic ecosystems. I鈥檓 honoured to be elected to the International Ozone Commission and to contribute to stewardship efforts for this vital planetary boundary.鈥
Ozone plays an important role in protecting the Earth from harmful levels of ultraviolet solar radiation and has a role as a greenhouse gas in the Earth's climate system. The ozone layer is protected by the Montreal Protocol on Substances that Deplete the Ozone Layer (1987), which is considered one of the most successful environmental agreements of all time.听
