china news service, beijing, september 6 (reporter sun zifa) the international research center for sustainable development big data, the world's first professional scientific research institution built and operated by the chinese academy of sciences to use big data to serve the united nations 2030 agenda for sustainable development, released the "sustainable development science satellite 1 thermal infrared image atlas", "sustainable development science satellite 1 low-light city cluster map" and "sustainable development science satellite 1 low-light image atlas (english version)" on september 6.

the series of atlases were released at the 4th international forum on big data for sustainable development held in beijing on the same day. among them, the "sustainable development science satellite 1 thermal infrared image atlas" is the world's first remote sensing thermal infrared image atlas; the "sustainable development science satellite 1 twilight city cluster map" is the world's first set of high-resolution color night light images of 10 major urban agglomerations in the world.
the thermal infrared image atlas of the sustainable development science satellite-1 includes 10 different types of landscape features in 118 different regions around the world, and comprehensively displays the thermal characteristics of typical natural landforms and artificial features, which is crucial for understanding surface energy balance, climate change, land cover and land use change, urban heat island effect, agricultural monitoring, and natural disaster assessment. at the same time, it shows the great potential of space observation technology to serve multiple sustainable development goals such as "zero hunger", "clean water and sanitation facilities", and "climate action", and provides valuable information and data support for research on global climate change, urban heat island effect, and natural resource management.
compared with the "sustainable development science satellite 1 low-light image atlas" released in 2023, the english version released this time added 31 cities in 28 countries, and collected a total of 10-meter spatial resolution color night light remote sensing images of 154 cities in 133 countries on five continents, comprehensively displaying the night light scenes of major cities around the world.
guo huadong, academician of the chinese academy of sciences and director of the international research center for big data on sustainable development, pointed out that the thermal infrared image atlas of the sustainable development science satellite-1 and the low-light city cluster map released this time are the world's first to show the thermal characteristics of different surface objects and the night scenes of major urban agglomerations in the world detected from space, providing a new detection perspective for the research on relevant sustainable development goals.
guo huadong said that the sustainable development science satellite 1 has proved its important role and value. in the future, he hopes to unite more countries, more united nations agencies and international organizations to jointly develop and launch a series of sustainable development satellites to form a constellation, continuously obtain valuable data resources of different layers and types of the earth, serve sustainable development and global economic recovery, and ultimately form an important space infrastructure that serves the world and serves the sustainable development of all mankind.

at the opening ceremony of the forum that day, the sustainable development satellite observation alliance, initiated by the international research center for sustainable development big data and seven satellite centers, officially announced the launch of the sustainable development satellite virtual constellation. the constellation includes the sustainable development science satellite 1, fengyun-3e, environmental disaster reduction 2a, resources-3 03, ocean 1c and china-pakistan earth resources satellite 04a. this has also become an important milestone in china's space technology capabilities in supporting the global sustainable development cause.
it is reported that the sustainable development science satellite 1 is the world's first scientific satellite dedicated to serving the united nations 2030 agenda for sustainable development. it is also the first satellite of the sustainable development satellite constellation planned by the international research center for sustainable development big data. it is equipped with high-performance low-light, thermal infrared and multi-spectral imagers. through the coordinated observation of these three payloads day and night, it can achieve "detailed depiction of the traces of human activities."
since its successful launch in november 2021, the sustainable development science satellite-1 has acquired more than 370,000 scenes of global nighttime lights, thermal infrared and multi-spectral data, serving the sustainable development research and decision-making support of relevant un agencies, international organizations and more than 100 countries around the world. more than 100 academic articles have been published using sdgsat-1 data, and 13 global emergency monitoring reports have been released by the united nations satellite center and the united nations office for disaster risk reduction.
