Data contains the concentration time series of 16 simulated odours equally spaced crosswind and symmetric with the midline, of a simulation of 2D grid turbulence, measured at a single location directly downwind and on the midline. To use this data, first clone the git repostory for the manuscript from https://github.com/stootoon/fisher-plumes. Then unzip this file in the top level folder of that repository. Finally, rename the resulting 'proc_share' folder to 'proc.'
