World Meteorological Organization - WMO
"The World Meteorological Organization (WMO) is a specialized agency of the United Nations. It is the UN system's authoritative voice on the state and behaviour of the Earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources."
A five-day weather forecast today is as reliable as a three-day forecast two decades ago, and this is worth billions of dollars to the global economy
More than 10'000 surface weather stations, 1'000 upper-air stations, 7'000 ships, 1'000 drifting buoys, 3'000 commercial aircraft, and 30 meteorological satellites contribute to weather and climate observations
Every dollar invested in basic weather observing system has the potential to achieve at least 25 dollars in returns
