Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment

Research Activities

LIAISE Mesoscale Model Setup and Intercomparison Study

The main objective of the model intercomparison in LIAISE is to evaluate the representation of the surface features in numerical models and its impact in the organization of the flow at lower levels.

Researchers from several operational numerical weather prediction and universities groups are currently performing mesoscale simulations for a case study centered over the Ebro basin. Two exercises are proposed. The first one (PRE‐LIAISE) will be based on a case previous to the LIAISE campaign to evaluate the sensitivity of the results in the model parameters (parameterizations, surface features, initial conditions, resolution, ...). The finalgoal is to find the best model configuration (that might be different for each model) that better captures the locally-generated circulations. The second exercise (IOP‐LIAISE) willbe based on an IOP of the LIAISE campaign (or several IOPs to assess how the models respond to the different land states and through different fluxes, atmospheric turbulence and the corresponding circulations) and it is expected that all the models will run with a setup defined in the PRE-LIAISE exercise. See the above web link for more information.

Projects with linkages to and collaborative projects with LIAISE

Human Imprint on Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment.
This project is funded by the French L'Agence nationale de la recherche (National Research Agency: ANR) and funds both research and a considerable portion of the field campaign.

Hydrological Understanding and Modeling of Iberian Drought

Irrigation and Drainage monitoring by remote sensing for Ecosystems and Water resources management

PIRAGUA addresses the characterisation of the hydrological cycle in the Pyrenees in order to improve the adaptation capacity of the territories to the challenges imposed by climate change and to support the investment aimed at adapting water resource management to climate change. Project results from this project are to contribute to the climate change topics of LIAISE.

The project aims at advancing capabilities towards a quantitative, accurate and routine estimation of irrigation information by means of multi-mission satellite EO approaches: Irrigation mapping, quantifying the irrigation amount and detecting the seasonal timing of irrigation.

Adaptation of water and land management is essential in the Mediterranean basin, which faces over-exploitation of water/soil resources and will experience important hazards due to change in climate forcing.
