MIRAVI: the Earth live
Have you ever wanted to track natural events in progress, such as fires, floods and volcanic eruptions, or simply explore the planet through the eyes of a satellite? ESA has created a website, MIRAVI, which gives access to the most recently acquired images from the world’s largest Earth Observation satellite, Envisat.
The annual Antarctic ozone hole mapped for us by satellites is a grim symbol of our atmosphere’s fragile complexity: supposedly harmless chemicals emitted by spray cans ravaged the layer of stratospheric ozone that protects all life on Earth from deadly ultraviolet radiation.
The intensity of UV radiation that reaches Earth is directly related to the ozone concentration in the atmosphere, which acts as a sun filter and protects us from harsh UV rays. Excessive UV radiation increases the risk of skin cancer, cataracts and weakened immune systems and also affects the health of fauna and flora.
The temperature of the surface of the ocean is an important physical property that strongly influences the transfer of heat energy, momentum, water vapour and gases between the ocean and the atmosphere.
World Fire Atlas (WFA)
More than 50 million hectares of forest are burnt annually, and these fires have a significant impact on global atmospheric pollution, with biomass burning contributing to the global budgets of greenhouse gases, like carbon dioxide.
Storm swells – a succession of large, long waves – are surprise factors that can have deadly consequences when they break on the shoreline. As they are generally preceded by calm water, it is often impossible to visually detect their arrival from shore.
