The Atmospheric Trace Molecule Spectroscopy Laboratory (ATMOSpeclab) designs, assembles, and validates innovative optical spectroscopic instruments. We conduct in-situ and remote sensing measurements of atmospheric trace gases, radicals, and aerosol optical properties.

We carry out field observations from land, aboard ships, and on research aircraft as well as conducting laboratory experiments. We integrate field and laboratory observations by constructing numerical models to understand the abundances, sources, and atmospheric chemistry of reactive trace gases and aerosols that are relevant to air quality and climate.
