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.

Weather prediction has achieved immense progress, driven by research and increasingly sophisticated telecommunication, information technology and observational infrastructure. Predictive skill now extends in some cases beyond 10 days, with an increasing capability to give early warning of severe weather events many days ahead.

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 science community is concerned: many established researchers plan to retire in the coming decade and there is a dearth of early and mid-career researchers ready to take their place and contribute in a meaningful way. Unless young scientists are encouraged, trained and mentored in various scientific fields knowledge gaps will occur.

Thanks to the HimawariCast project led by WMO and the Japan Meteorological Agency, 14 countries in the Asia-Pacific can now access vital meteorological data from the Himawari-8 satellite. The project is sending teams to each of the countries to provide technical assistance for obtaining and using the data. As presented on the side lines of this week’s meeting of the WM Executive Council, the aim is to ensure that Himawari-8 data will continue to support improved preparedness in the face of natural hazards and disasters, which are occurring with increased frequency in the region. The Himawari-...

A new era in satellite meteorology offers unprecedented opportunities to improve Earth observations and understanding, but also poses big challenges for users worldwide. A top-level World Meteorological Organization delegation outlined WMO’s strategic perspectives at the US National Oceanic and Atmospheric Administration Satellite Conference 2017 . The latest generation of satellites from China, Europe, India, Japan, the Republic of Korea, Russian Federation and the USA and other countries is becoming operational, providing unprecedented advances in weather forecasting, disaster risk...

The United States has launched the first of its new generation of highly advanced polar-orbiting meteorological satellites. Known as JPSS-1 (for Joint Polar Satellite System), the new satellite is the first in a series of missions that the US is contributing to the space-based component of the WMO Integrated Global Observing System (WIGOS) through to 2038.

The World Weather Watch (WWW) is one of the crowning achievements of WMO. The celerity with which WMO responded to the introduction of meteorological satellites with the establishment of the WWW, and its subsequent adoption by all WMO Members, set a standard for international cooperation in operational programmes that remains unequalled today.

At 05:16 UTC on 7 October 2014, the Japanese satellite Himawari-8 atop an H-IIA rocket took off from the Yoshinobu Launch Complex Pad 1 at the Tanegashima Space Centre in Japan. The launch was flawless and the satellite arrived a few weeks later at its final geostationary orbiting position 36 000 km above the equator at 140.5°E, just north of Papua New Guinea in the Western Pacific Ocean. It was the first of a new generation of satellites that would start operations in the 2015-2021 timeframe. These new meteorological satellites have enhanced observation capability that will bring benefits,...
