UK (CU)_ Scientists have put forward a new technique for assessing the impacts of ozone-destroying substances. The Integrated Ozone Depletion (IOD) metric can be used by researchers and policymakers focusing on the ozone. The study appeared in the journal Nature and is likely to be welcomed by environmentalists who have been raising the alarm on its destruction.
The IOD can take into account the effects of unregulated emission of substances that cause destruction to the ozone layer, while examining the rate of success for the ozone layer protection levels.
The Montreal Protocol which was concluded back in 1987 and enforced from the 1st of January 1987 has largely been successful in blocking chlorofluorocarbons (CFCs). Under the Montreal Protocol ozone depleting substances (ODS) have to be reduced or eliminated and with concerns over atmospheric pollution being a primary focus now more than ever, any development that helps large segments will be positive. Large segments of the population concerned for many decades about the destruction of the environment where some say its too late, however optimists believe measures can still be taken. Policymakers will need to take into account the current economic situation when implementing any new environmental reforms.
The IOD sheds light on the consequences of any new emissions on the ozone layer with 3 factors which are the emission strength, duration it remains in the atmosphere, and the chemical destruction level of the ozone.
The method was formed by the National Centre for Atmospheric Science at the University of Cambridge and the National Centre for Earth Observation at the University of Leeds. Professor John Pyle, from the National Centre for Atmospheric Science and the University of Cambridge, who focused on ozone depletion in the stratosphere throughout his career, assisted in developing the Montreal Protocol and led the study.
The IOD metric was produced from a computer model of the environment, known as the UK Chemistry and Aerosols model (UKCA).
