Stratospheric Science

Satoshi NISHIDA

The stratosphere is a region of Earth's atmosphere that extends from approximately 10 km to 50 km altitude, characterized by increasing temperatures with altitude. This temperature distribution arises because ozone (O3) molecules in the stratosphere absorb a portion of the incoming ultraviolet (UV) radiation from the Sun, undergoing chemical reactions that convert the energy of light into heat. Distinct from the troposphere where we reside below 10 km altitude, the stratosphere exhibits features such as lower pressure, minimal atmospheric moisture, and intense UV radiation. These unique characteristics present the stratosphere as a realm with potential for new scientific exploration. By harnessing these features, the stratosphere offers opportunities for novel scientific endeavors and applications.
