Sentinel data are fed into a series of Copernican services to address the challenges of urbanization, food security, sea level rise, polar ice reduction, natural disasters and climate change</ p>

<

p > the six expanded tasks of the Copernican Sentry will increase the existing capacity of the sentry, thus further addressing the gap between EU policy priorities and Copernican user needs</ p>

p > the chime mission, which carries a novel imaging spectrometer, will provide systematic hyperspectral images to map land cover changes and help sustainable agricultural practices. In addition, it will be used to detect different soil characteristics in order to take action to improve soil health. In addition, chime will be used to support forest management and assessment of biodiversity, ecosystem sustainability and environmental degradation, and to monitor lake and coastal ecosystems, including water quality</ p>

<

p > in order to prepare chime for future missions, as part of the cooperation between ESA and NASA Jet Propulsion Laboratory (JPL), scientists recently jointly carried out hypersense experiment, which should have been carried out in 2020, but covid’s restrictions meant that it had to be delayed</ p>

<

p > this activity is managed by the University of Zurich. First, it involves bringing an aircraft and JPL measuring instruments from the United States to Dubendorf Air Force Base near Zurich, Switzerland. It is reported that the next generation airborne visible infrared imaging spectrometer (AVIRIS) is similar to the ability of chime after entering orbit</ p>

<

p > AVIRIS measurements at more than 20 test sites representing different types of ecosystems are helping scientists and engineers prepare and ensure that chime can assume the responsibility of providing high-quality diagnostic and quantitative data immediately after orbit and operation</ p>

p > most of these flights are consistent with measurements on the ground, which can help further evaluate the data collected by airborne instruments</ p>

<

p > as part of this airborne and field activity, they also established a cooperative relationship with the Italian Space Agency and observed the test site from space with their satellite imaging spectrometer called PRISMA. In addition, the German Aerospace Center also provided hyperspectral images from its DESIS sensor, an imaging spectrometer overlooking the earth from the international space station</ p>

<

p > the resulting data set will include simultaneous ground, air and space observations, which will help improve the diagnosis and quantitative analysis of these imaging spectrometer “fingerprint” data</ p>

<

p > Michael RAST, a chime mission scientist of ESA, pointed out: “these data sets will help us establish and evaluate future chime data products, including specific agricultural vegetation components such as chlorophyll and nitrogen. In addition, they can quantify the carbon content in soil, so as to support the improvement of agricultural practice and management.” </ P >

<

p > the cooperation with NASA also includes chime and NASA’s surface biogeography (surface biology Geology) coordinated preparation between missions, which has spectrometer observation characteristics similar to chime. Both missions are planned to be launched in the second half of the next decade. </ P >

p > Robert O. green, chief researcher of aviris-ng, said: “From the perspective of covid and weather, this is a challenging activity, but the team has persevered and collected an extraordinary set of imaging spectral data sets to support chime and NASA’s future mission of surface biogeography to benefit our planet.” </ P >

<

p > “Since food security is a global issue, the cooperation of space agencies is crucial so that we can use our relative expertise and assets to obtain the best results. In this case, we have ESA, NASA, ASI (Italian Space Agency) and DLR (German space agency) Working with senior scientists from Europe, the United States, Israel and Australia – it’s absolutely incredible, “Dr. RAST added
