Time series, map and CH4 fluxes for offshore plume (Sept 1st 2016). Panel A shows a map of the plume transects with markers colored by altitude and CH4 concentrations colored by size. The dotted line is the plane through which the flux was calculated. Panel B shows a plot of the cross-wind concentration profiles of each plume transect (rainbow colored red to purple in order of acquired data point). Wind barbs (white) point into the wind. Panel C shows CH4 fluxes through the plane in Panel A, backgrounded and averaged in each grid cell. A point in a grid cell indicates a direct measurement; the other cells contain fluxes linearly extrapolated to the top of the boundary layer. DOI: https://doi.org/10.1525/elementa.308.f4
