High-frequency stratiform and convective rainfall isotope and meteorological database from Rio Claro, Brazil

Complete database of high-frequency sampling of rainfall events in the Rio Claro, São Paulo State, Brazil, between 2019 and 2021. Local: Rio Claro, state of São Paulo, Brazil (-22.39°S, -47.54°W, 670 m a.s.l.). File contents: 32 columns and 202 rows Units of measurement given in the table for each parameter. Isotopic data: oxygen-18, deuterium and excess deuterium (permil unit); Collected every 5-10-30 minutes depending on rainfall intensity. Meteorological data: Decagon Automatic Weather Station (AWS) Em50 including rain rate (ARR, mm), temperature (T, °C), relative humidity (RH, %), dew point (Tdew), lifting condensation level (LCL, m) was calculated using AWS RH and T data following Soderberg et al. (2013). - Micro Rain Radar (MRR-2, METEK): Reflectivity (Z, dBZ), fall velocity (w, m s-1), liquid water content (LWC, g m-3), and radar rain rate (Rrr, mm). Measurements closer to the surface, between 150 and 350 meters. - GOES-16 band 13 satellite: brightness temperature, taken every 10 minutes.
