Although the amount of water present in the atmosphere constitutes a minimum part of that existing on our planet, its relevance is vital. Water in the atmosphere regulates air temperature, is significant in the water cycle, in climatic phenomena and even in natural disasters.
This very small proportion of water, which only represents around 0.0009 per cent of the planet’s water, is at the centre of the processes that determine the weather, the hydrological cycle, atmospheric chemistry and the development of life. Thus, water is the main regulator of the earth’s temperature.
But did you know that every day the Sun evaporates more than one billion tons of water?
