THz-reflection spectroscopy was used to extract time-varying water gradients in drying paper targets mounted on
electrically thick dielectric substrates. The data showed a pronounced and prolonged drop below dry reflectivity when the water content that peaks at low weight (~ 10%). A binomial distribution fitted to the acquired data confirms the existence of
the time-varying water content gradient and suggests aqueous thin film hydration can be quantified even when the contrast between the film and backing material is low.
