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.

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.

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...
