The Earth’s protective ozone layer is well on track to recovery thanks to a highly successful environmental agreement which marks it 30th anniversary on 16 September. The Montreal Protocol on Substance which Deplete the Ozone Layer achieved a near 99 per cent phase-out of ozone destroying substances like chlorofluorocabons (CFCs) which were once commonly used in products ranging like refrigerants and aerosols.

Seven new generation geostationary satellites will be launched into positions over the equator within the next five years. These launches will drastically change the Space Component of the WMO Integrated Global Observing System (WIGOS) and National Meteorological and Hydrological Services are challenged to prepare for the advanced capabilities the satellites will offer. The imager capabilities, sampling rate, spectral resolution and spectral channels, of this new generation of satellites will drastically increase data rates – by an order of up to 100. All National Meteorological Hydrological...

The Montreal Protocol on Substances that Deplete the Ozone Layer, signed in 1987, has been successful in that the amount of chlorofluorocarbons is now slowly diminishing. A common misunderstanding, however, is the belief that the ozone problem has been solved and the ozone layer is back to its original state.

Countries are meeting in Montreal this week to mark the 30th anniversary of the world’s most successful ever environment agreement, which halted the destruction of the protective ozone layer. The 197 parties to the Montreal Protocol on Substances which Deplete the Ozone Layer are gathered in the Canadian birthplace of the treaty. This achieved a near 99 per cent phase-out of ozone destroying substances like chlorofluorocabons (CFCs) and hydrochlorofluorocarbons (HCFCs), once commonly used in products ranging like refrigerants and aerosols.

The space-based observing system is making essential contributions to the generation of weather, water and climate-related products and services and helps support policy- and decision making. The number of operational satellites that are part of this space-based observing system and their capabilities is growing, and a considerable number of satellites with new capabilities that are presently in the planning stage will soon join the system.

Air quality regulations and anti-pollution measures in Europe and North America have had very positive impacts on air quality. Since the year 2000, both average and peak surface ozone concentrations have levelled off and even started to fall at some locations after increasing throughout the twentieth century, according to a new report from the World Meteorological Organization.

The World Meteorological Organization has joined the global commitment to reduce deaths due to air pollution by two thirds by 2030. At the World Health Organization’s first ever Global Conference on Air Pollution and Health , WMO pledged to strengthen the quality and availability of pollution observations, enable provision of air quality forecast and advisory services and incorporate health impacts in key scientific assessments on climate and climate change.
