This dataset includes raw data logs of indoor and outdoor water capture tests. The dataset also includes Mathematica code to calculate and generate convection-limited water capture fluxes. The data logs are TSV text files where the columns correspond to time (seconds), wind tunnel temperature (C), wind tunnel humidity (%), humidity setpoint (%), liquid desiccant chamber temperature (C), liquid desiccant chamber humidity (%), measured volume (mL). Links to this data are included in our paper. The Mathematica code relies on external datasets listed in the mapping_plots.nb file
