Research groups such as the University of Electro-Communications, Information and Communication Research Organization, Meiji University, National Polar Research Institute, and Kyushu University are using the geostationary meteorological satellite "Himawari 8" to observe luminous clouds at altitudes of 80 to 85 km. Developed the method.Noctilucent clouds are thought to be promoted in response to global warming, so they are likely to help clarify climate change.
According to the University of Electro-Communications, the noctilucent cloud is actually an ice particle, and it is thought that its formation is promoted in response to the cooling of the upper sky region due to global warming.It is called "climate change canary" because it can be used as an index for super-high-rise cooling and global warming.
The research group focused on the global image of Himawari 8 around the earth, devised a method for monitoring noctilucent clouds in real time, and developed a system to be applied to the data of Himawari 8.Although it will be observed from an ultra-long distance of 3 km, the sensitivity is equivalent to that of NASA's (US Aerospace Agency) noctilucent cloud observation satellite, which observes from an altitude of 6,000 km, with sufficient sensitivity for fluctuations in the noctilucent cloud. Demonstrated that it can be observed.
Real-time monitoring data is open to the public through the University of Electro-Communications website.Details of the research will be announced at the general meeting and lecture of the Earth Electromagnetic and Earth and Planetary Society on November 11.
