Sensitivities of atmospheric composition and climate to altitude and latitude of hypersonic aircraft emissions [PDF]
Atmospheric Chemistry and PhysicsHydrogen-powered hypersonic aircraft are designed to travel in the middle stratosphere at approximately 30–40 km. These aircraft can have a considerable impact on climate-relevant species like stratospheric water vapor, ozone, and methane and thus would ...
