The possibility of simultaneously studying the measurements taken at two grassland sites and a forest site in a temperate climate provides CloudRoots with the opportunity to relate the specifics of each ecosystem to similar cloud cycles. Special attention will be paid to the differences and relationships between water use efficiencies, evaporative fractions and cloud variables. In this ecosystem, we have the advantage of being an active partner of the Ruisdael observatory  both in the collection of measurements (including the carbon and water vapor isotopologues and isofluxes) and the simulation in the DALES testbed of the three stations (see dashed line in the figure). This could provide an unprecedented level of detail for calculations and validation of the surface fluxes and cloud cycles, i.e., spatiotemporal scales of 100 meters and seconds.
