Observational data from the TEEMS (Transport and Energy Emissions from Manhattan Streets) campaign

As part of the New York Atmospheric composition and Air Quality (NYAAQ) program, we used the NYAAQ mobile laboratory to sample trace gas enhancements from methane street leaks and transportation. We deployed an Aeris MIRA Ultra N2O/CO/H2O, an Aeris MIRA Ultra C2H6/CH4/H2O, a LI-COR LI-7810 (CO2/CH4/H2O) and a GPS receiver. Deployments were conducted over five consecutive days in Winter (January 27-31 2025) and Summer (June 2-6 2025), sampling the Upper East Side and East Harlem neighborhoods in Manhattan, NYC (72nd −110th Street, 1st −5th Avenue).
