Movie S1.mov Hygroscopic growth of a 4 μL droplet of ~41 wt% aqueous CaCl2 at~90% ambient relative humidity (RH) is shown in the top video (scale bar, 1 mm). Evaporation ofa 12.5 μL water droplet at ~10% RH is shown in the bottom video (scale bar, 1 mm). Figure 3 is calculated from the rate constants fitted to the mass traces inFigures 1 and 2 and has no data file of its own. AMBIENT MEASUREMENTS Sensirion SHT4xA, serial 4029183529, on a SensorBridge, logged at 2 Hz withControlCenter 1.38.0. The .edf files are the raw instrument output. They are tab-delimited UTF-8 textwith a header of '# key=value' lines, followed by the columns Epoch_UTC,Local_Date_Time, temperature and relative humidity. No Sensirion software isneeded to read them. TRIMMING Logging was started before each experiment and stopped at or near its end, soevery log is longer than the run it contains. The ambient-conditions workbookshold only the window used in the analysis: a span equal to the experimentduration, ending either at the end of the log or, where the enclosure was openedbefore logging stopped, immediately before the step change in relative humiditythat marks it. Those step changes are accompanied by a simultaneous drop intemperature and are resolved to within one 0.5 s sample. Workbook columns are time_s, elapsed seconds from the start of the window;T_degC; and RH_percent. Time steps are the sensor's own and are close to but notexactly 0.5 s. No smoothing, filtering, interpolation or gap-filling was applied;values are as reported by the sensor. The raw logs are included so the discarded portion of each file can be recovered.
