The station is managed by the Observatoire de la Zone Critique de la Réunion (OZC-R) from Observatoire des Sciences de l'Univers de La Réunion (OSU-Réunion, Université de La Réunion). This is a forest station located at 1285m asl in the Reunion National Park. Rainwater is monthly collected (PALMEX rain collector) for δ18O and δ2H water isotopes analysis from 2016. Analyses are carried out at the Institut de Physique du Globe in Paris (PARI analytical platform) and within the IR-OZCAR network. The major ions rainfall composition is also studied. The station also measures several meteorological variables outside the canopy (precipitation, atmospheric pressure, temperature, relative humidity, global and photosynthetically active radiation) but also humidity linked to clouds and fog, as well as ground temperature.

The station is managed by the Observatoire de la Zone Critique de la Réunion (OZC-R) from Observatoire des Sciences de l'Univers de La Réunion (OSU-Réunion, Université de La Réunion), and located at 80m asl at the Reunion University. Rainwater is monthly collected (PALMEX rain collector) for δ18O and δ2H water isotopes analysis from 2001. Analyses are carried out at the International Atomic Energy Agency as part of the global network for measuring isotopes in precipitation (GNIP-IAEA).

This dataset has been produced in the framework of the CALHYCO research programme: Characterization of hydrodynamics coastal hazards. This dataset contains: 1) in-situ records of water level and wave height parameters from spectral analysis, on a transect perpendicular to the reef, at the reef slope (RS) and the reef flat (RF). 2) Numerical modelling of water levels and wave heights on the reef using the XBeach model in "surf beat" mode A "readme" file, downloadable with the data files, describes the nomenclature of the files and the variables measured. These in-situ surveys took place on the western side of La Reunion Island (Indian Ocean) in a microtidal zone frequently exposed to Southern Ocean swell and cyclonic events. Coral reefs represent an efficient natural mechanical coastal defense against ocean waves. The objective of CALHYCO is to provide a better understanding of the coastal defense characteristics of the reef system against these events.
