Space wise.
Earth smart.

Himawari 8 and 9, the next generation of Japanese Geostationary Meteorological Satellite

Observation Functions

The visible and infrared radiometer (camera) of the Himawari 8 and 9 will provide continuous imagery data with approximately two times greater spatial resolution than the Himawari 7, and scans the entire globe in one-third the time it previously took—from 30 to 10 minutes. It can also provide frequent images of small areas such as the area around Japan, tracking of typhoons and volcanic ash(es). Furthermore, the number of spectral bands has been increased from 5 to 16 for even greater monitoring of atmospheric conditions and the global environment.
