Explanation:

• The US Space agency National Aeronautics and Space Administration (NASA) is developing a new system called the Earth System Observatory, to mitigate efforts related to climate change and disaster mitigation.
• The Earth System Observatory will be a set of missions designed to study “designated observables” such as aerosols, clouds and weather, water supply, and the Earth’s surface and ecosystems, for an unprecedented understanding of the critical interactions between Earth’s atmosphere, land, ocean, and ice processes, which determines how the changing climate will play out at regional and local levels, on near and long-term time scales.
