Short summary
The ozone layer in the stratosphere protects life from harmful UV light, but chlorine-based pollution threatens to damage it. We developed an instrument that couples a laser with highly reflective mirrors and advanced electronics to measure an important residue of this pollution: hydrogen chloride. Our instrument has an improved, more modern layout that we successfully tested in flight. This paves the way for future, advanced techniques that seek to evaluate the health of Earth’s ozone layer.
