Earth in Flux
NISAR is distinguished by first-of-a-kind technology that measures Earth’s solid surfaces, cryosphere, and ecosystems with unprecedented coverage, consistency, and precision. It reaches beyond science-driven discovery to include a wide range of humanitarian applications. As the Earth’s surface is constantly in flux, so too are the faces of these clocks, each of which tells the time of a location that illustrates the changes NISAR will observe.
NISAR spots changes to the surface of the Earth to 3 cm of accuracy. That’s like reading the time on this clock from as far away as Albuquerque, New Mexico.
NISAR collects data under every atmospheric condition. With eyes “on” at all times, the steady transformation of Earth’s surface is witnessed without interruption, even in the cloudiest of locations.
NISAR circles the Earth in about 100 minutes, taking 12 days to complete the most up-to-date and comprehensive data collection of our planet’s land and ice-covered surfaces.
Moving beyond pure science, NISAR delivers data for urgent response, leading to better forecasting and risk assessment of floods, fires, volcanoes, landslides, earthquakes, oil spills, and dam collapses.
NISAR’s data differentiates seasonal fluctuations from long-term trends, showing how rapidly, and where, loss of major ice sheets will occur.
SEA LEVEL RISE
NISAR measures changes to our coastlines due to the melting of glaciers and ice sheets, revealing their impact on sea level now and in the future.
REPLETION AND DEPLETION
NISAR observes the transformation of our ecosystems from forests to farmlands and deserts, indicating how changing climate and land use affect the carbon cycle and species habitat.
NISAR observes the stresses from industry, agriculture ,and transportation on Earth’s ecosystems, functions, and services.
NISAR measures deforestation and the subsequent loss of sequestered carbon, which impacts the quality of air that we breathe.
NISAR measures land that sinks from natural causes as well as from the over-extraction of resources like groundwater and oil.
NISAR provides near real-time data of our planet’s solid surface deformation, improving forecasts of large-scale geological hazards in a socially relevant time frame.
