NOAA’s Chemical Sciences Laboratory won for developing a new laser-based instrument to measure SO2 at extremely low mixing ratios relevant to the stratosphere. The instrument, built and deployed in record time, will enable better understanding of atmospheric sulfur chemistry and transport, which is critical to understanding the stratospheric aerosol layer, including impacts from geoengineering. The new instrument’s detection limit is 50-fold better than previous technologies and it is already is allowing investigation of science questions previously impossible to tackle. This project grew out of a 2013 CIRES Innovative Research Project.
