Developing a chemical conversion resonance fluorescence device to measure ClO and BrO in the upper atmosphere

Harvard University, ES96-Engineering Design, Spring 2017

Intense summer storms can cause convective injections in the US midwest in the summer. These convective injections deposit water into the lower stratosphere and increases the concentration of chlorine and bromine radicals, causing rapid ozone depletion. Because of these environmental phenomena created by climate forcing, we developed a chemical conversion resonance fluorescence device that will measure chlorine and bromine concentrations over a period of 3 months in-situ on an unmanned aircraft developed by Aurora Flight Sciences. In this project, I worked on the detection axis to help develop an Atomic Line Spectrum Absorber in addition to evaluating new materials to improve the instrument.
