Below you will find a list and description of the files included in this data publication.

VARIABLE DESCRIPTION FILE (1)

1. \Data\_variable_descriptions.csv: Comma-separated values (CSV) file containing a list and description of variables found in all data files. (A description of these variables is also provided in the metadata below.)

Columns include:

Filename = name of data file
Variable = name of variable
Units = units (if applicable)
Description = description of variable


DATA FILES (81)

1-80. \Data\Lab[X]_[RH]_[REP].csv: CSV files (80) containing time, mass, relative humidity, and temperature data for the sorption step of interest where [X] = lab identifier, [RH] = target relative humidity (in percent), and [REP] = replicate number.

Variables include:

Time (min) = time in minutes since the start of the sorption step of interest
Mass (mg) = sample mass in milligrams (mg)
Relative humidity (%) = percentage of relative humidity measured near the sample
Sample Temp (°C) = temperature in degrees Celsius (°C) measured near the sample


81. \Data\SummaryList.csv: CSV file containing a list of the 80 data files and the associated target relative humidity, initial dry mass, and final dry mass for each file.

Variables include:

Filename = name of data file
Target RH Step = target range of relative humidity (0-10%, 10-20%, ..., 90-95%)
Initial Dry Mass (mg) = initial dry mass in mg
Final Dry Mass (mg) = final dry mass in mg
