Characterizing Rainfall Simulators by Raindrop Size Distribution Measurements and Fall Velocity Estimates

This dataset contains the processed experimental data for the research article: "Characterizing Rainfall Simulators by Raindrop Size Distribution Measurements and Fall Velocity Estimates" The data was collected to evaluate and compare different methods for measuring raindrop fall velocity in laboratory settings, specifically for drip-type and pressurized rainfall simulators. The core purpose was to assess the reliability of an empirical velocity relationship (Eq. 1 in the paper) against a direct photographic technique and Parsivel² optical disdrometer.

The dataset is organized into two main blocks corresponding to the experimental setups. Drip-type Rainfall Simulators. For each experimental conditions (raindrop diameter, D (cm), and falling height, h (m)), the following variables were obtained: - vD (m/s): Fall velocity measured by the photographic technique. - vcalc (m/s): Fall velocity calculated using the empirical relationship (Eq. 1). - vi, P (m/s): Fall velocity measured by the Parsivel² disdrometer.
