$246,164Benefit:
Development of a robust, sensitive instrument to measure aerosol absorption will provide a range of benefits to the Navy, other federal agencies, and the broader public. Light absorption by aerosols is an important component of climate change, with light absorbing aerosols having a strong warming impact on the atmosphere. Current research lacks a reliable method for measuring atmospheric absorption, critical for evaluating global models that predict future climate. Unlike greenhouse gases, aerosols have short atmospheric lifetime, making them stronger candidates for emission reduction scenarios. Light absorbing particles also affect atmospheric visibility, and current measurements designed to monitor and improve visibility in protected areas lack accurate measurements needed to inform policy choices. Finally, there are few, if any, commercial instruments on the market sufficient for measuring absorption from airborne platforms at high time resolution, which our proposed instrument would be able to deliver. The instrument would have immediate commercial applications in meeting a long standing need in the atmospheric research community for a high performing, reliable instrument. In the longer term, it is possible that light absorbing aerosols will be regulated due to their impact on climate. If so, there would be a large demand for aerosol absorption instrumentation for monitoring and emissions testing, both large commercial markets. The instrument we develop here would feature technology that could be translated into a simplified, less sensitive version to address monitoring requirements, and the integrated calibration system we will develop would be critical for establishing a standard measurement approach that can be deployed continuously.
