  • Meteorological observations from weather stations interpolated on a 25x25 km grid, on a daily basis from 1979 to the last calendar year completed, for France. Meteorological observations are freely accessible via OGC SensorThings Standard service : https://frost.geosas.fr/agri4cast/v1.0/ Observed properties : - maximum air temperature (°C), - minimum air temperature (°C), - mean air temperature (°C), - mean daily wind speed at 10m (m/s), - vapour pressure (hPa), - sum of precipitation (mm/day), - potential evapotranspiration from a crop canopy (mm/day), - total global radiation (KJ/m2/day), More informations on Agri4cast Resources Portal : https://agri4cast.jrc.ec.europa.eu/DataPortal/Index.aspx

    This data set contains the temperature values at the position of 557 Pardosa saltans spiders, measured each minute during 90 minutes in a laboratory thermal gradient. Additionnal information on sex, development stage and morphology is provided for each individual. For details see Cabon et al 2023 in Journal of Thermal Biology: https://www-sciencedirect-com.passerelle.univ-rennes1.fr/science/article/pii/S0306456523002474 https://doi.org/10.1016/j.jtherbio.2023.103706

    The Ploemeur-Guidel observatory (Britanny, France) is focusing on surface-depth relationships in a fractured crystalline geological context and oceanic climate. It is built on 2 sub-sites, one highly anthropized, the other in natural state. In Ploemeur, groundwater has been pumped since 1991, supplying more than 1 million m3 of clean drinking water annual at a sustainable rate. Such high productivity is explained the specific fractured network in granite and micaschists, draining deep geological layers (~400 m). Extracted water quality is very good, with limited nitrate concentration, in a region that has been strongly affected by widespread pollution. Guidel site is in a similar, but natural context. Deep iron-rich groundwater is upflowing, creating surface and deep groundwater-dependent ecosystems, and feeding a classified coastal wetland. Both sites have a very dense equipment to study rapid to long-term surface-depth exchanges: a flux tower, unsaturated zone monitoring, a network of ~50 shallow (<10m) and deep boreholes (>80m), hydrochemical, temperature and deformation. An well-characterized fractured experimental site offers the possibility to conduct experiments to test innovative instruments and develop new methodologies

    Groundwater comprises approximately 30 percent of the Earth’s total freshwater, serving as a vital resource for both humans and ecosystems. As an essential source of drinking water for humans and sustenance for vegetation, groundwater plays a key role in the terrestrial water cycle. It acts as a buffer, enabling adaptation to climate variability and extreme events like floods and droughts. Therefore, understanding groundwater storage is important for both ecological and15 societal reasons.
