It is difficult to observe airglow emission in the city.

There are the layers of airglow emission in the sky. For example, the layer of OH emission is in 86km altitude and O emission layer is in 96km altitude. Most of airglow observations has been made from the ground.

Airglow observation data by the Reimei satellite, it is in sun synchronus orbit at 650km altitude, is used in our research. Reimei satellite observes airglow emission in the Earth limb direction. The objective of this study is to determine the spatial distributions of airglow emission from the satellite limb observation data.
