Evapotranspiration evaluation by 3 different protocols on a large green roof in the greater Paris area

Abstract. Nature-Based Solutions have appeared as relevant solutions to mitigate urban heat islands. To improve our knowledge on the assessment of this ecosystem service and the related physical processes (evapotranspiration), monitoring campaigns are required. It was the objective of several experiments carried out on the Blue Green Wave, a large green roof located at Champs-sur-Marne (France). Three different protocols were implemented and tested to assess the evapotranspiration flux at different scales. The first one was based on the surface energy balance (large scale). The second one was carried out by an evapotranspiration chamber (small scale). The third one was based on the water balance evaluated during dry periods (punctual scale). In addition to these evapotranspiration estimates, several hydro-meteorological variables (especially temperature) were measured. Related data and Python programs providing preliminary elements of analysis and graphical representation have been made available. They illustrate the space-time variability of the studied processes regarding their observation scale. The dataset (Versini et al., 2023a) is available here:

Short summary
Nature-Based Solutions, as green roofs, have appeared as relevant solutions to mitigate urban heat islands. The evapotranspiration process conducts the ability of NBS to cool the air. To improve our knowledge about evapotranspiration assessment, this paper presents some experimental measurement campaigns carried out during 3 consecutive summers. It makes the data available for 3 different spatial scales (large, small and punctual).
