Human imprint on Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment – HILIAISE

The overarching objective of HILIAISE is to better understand and model the human imprint on semi-arid energy and water cycles.
To obtain this objective:
1) The project will have a long term field campaign with a 15-day Special Observing Period during summer 2020 over the Ebro basin in northeastern Spain when land surface heterogeneities are at their maximum. This campaign will focus on surface and boundary layer contrasts between irrigated and non-irrigated natural regions, and quantifying the water resource demand.
2) The project will use a multidisciplinary approach using a suite of hydrological, land-surface and meteorological models focusing on both using existing and improving parameterizations of anthropization and semi-arid surfaces.
The improved representation of anthropogenic and semi-arid processes in models will form the foundation for improving the understanding and prediction of water resource changes for the recent past, present and under future climate change.
