The TgML model contains a machine-learning algorithm that was trained to predict the glass transition temperature Tg of molecular organic substances relevant to the atmosphere.
An online version of the model can be accessed here: TgML Online Model
We also provide the underlying data set of experimental glass transition temperatures here: BIMOG Database
