Urban Emissions of Water Vapor in Winter.

ABSTRACT: Elevated water vapor (H₂O_v) mole fractions were occassionally observed downwind of Indianapolis, IN, and the Washington, D.C.-Baltimore, MD, area during airborne mass balance experiments conducted during winter months between 2012 and 2015. On days when an urban H₂O_v excess signal was observed, H₂O_v emissions estimates range between 1.6 × 10⁴ and 1.7 × 10⁵ kg s^-1, and account for up to 8.4% of the total (background + urban excess) advected flow of atmospheric boundary layer H₂O_v from the urban study sites. Estimates of H₂O_v emissions from combustion sources and electricity generation facility cooling towers are 1-2 orders of magnitude smaller than t
