NASA Earth System Observatory to help address climate change
NASA has announced an Earth System Observatory that will guide efforts related to climate change, disaster mitigation, fighting forest fires, and improving real-time agricultural processes. NASA will design a new set of Earth-focused missions to provide key information to guide efforts related to climate change, disaster mitigation, fighting forest fires, and improving real-time agricultural processes using the observatory.
Each satellite from this new observatory will be uniquely designed to complement the others, working in tandem to create a 3D, holistic view of Earth, from bedrock to the atmosphere.
NASA administrator Senator Bill Nelson comments: 'Over the past three decades, much of what we’ve learned about the Earth’s changing climate is built on NASA satellite observations and research. NASA’s new Earth System Observatory will expand that work, providing the world with an unprecedented understanding of our Earth’s climate system, arming us with next-generation data critical to mitigating climate change, and protecting our communities in the face of natural disasters.’
The observatory follows recommendations from the 2017 Earth Science Decadal Survey by the National Academies of Sciences, Engineering and Medicine, which lays out ambitious but critically necessary research and observation guidance.
Areas of focus for the observatory include; aerosols, cloud, convection, and precipitation, mass change, surface biology and geology, surface deformation and change.
NASA is currently initiating the formulation phase for the observatory. Among its first integrated parts is NASA’s partnership with the Indian Space Research Organisation (ISRO), which brings together two different kinds of radar systems that can measure changes in Earth’s surface less than a half-inch.
This capability will be utilised in one of the observatory’s first missions intended as a pathfinder, called NISAR (NASA-ISRO synthetic aperture radar). This mission will measure some of the planet’s most complex processes such as ice-sheet collapse and natural hazards such as earthquakes, volcanoes, and landslides. NISAR can assist planners and decision-makers with managing both hazards and natural resources in the future.
