Lizzy Asher is securing inert stainless steel canisters in the base of the Unmanned Whole Air Sampling System (UWASS). These 100 mL canisters collect whole air samples and are pressurized to maximize the volume they collect. After the UWASS lands, this array of canisters is subsampled and analyzed using the Trace Organic Gas Analyzer (TOGA) for ambient mixing ratios of ~ 70 volatile organic compounds.
