The Hydro-climatological Observation & Sensing Technology (HOST) team is driven by the need for providing the scientific community and public stakeholders with valuable information on the changing environmental conditions through the development of knowledge, innovation and technologies. It aims at developing a fully-fledged environmental assessment framework where various measurement and monitoring approaches are integrated. With this structured information on environmental conditions across the country, HOST provides strategic inputs to environmental research and supports key policy-making processes where Luxembourg has legal obligations at national and European level. To achieve this, HOST relies on three interconnected competence pillars in hydro-climatology, mechatronics, and unmanned aerial vehicle (UAV) - remote sensing.
Innovative instrumentation and campaign-style measurements to quantify the composition and fluxes of water, solutes and sediments as well as weather parameters at different spatial (i.e., plot to watershed) and temporal (event to millennial) scales across Luxembourg.
Building up cutting-edge engineering solutions for a wide range of environmental research applications. This active interface between industry and science transfers research results into market-oriented products, processes and services, and provides specialised companies with an easier access to state-of-the-art research outcomes through the development of models and prototypes.
Developing semi-automated data processing chains for the acquisition and analysis of hyperspectral images from drones and supporting high-quality Unmanned Aerial System (UAS) services.
Implementation and management of nested hydro-climatological observation network across a range of topographic settings, bedrock geologies, soils and land use types to document and report on the recent changes in climatic conditions and water resources in Luxembourg.
Innovative techniques and monitoring strategies are being developed and tested at several experimental sites in Luxembourg to quantify and better understand key processes taking place through several components of the Critical Zone (e.g. soils, rivers, vegetation).
Sampling and providing detailed description of humus and soils and classifying them according to international classification system (World Reference Base).
Spectral profiling from lab to field scale (soil, vegetation, artificial surfaces), airborne small- and large-scale thermal mapping (supporting scientific projects on precision agriculture, vegetation stress, biodiversity and disease detection)
Development and implementation of low energy consumptive technology for environmental and ecological monitoring purposes. Such prototype development and deployment are directly useful for several different research teams of the ERIN department.
Environmental data generated within our monitoring network and through our technological solutions both feed into fundamental research projects on hydro-ecosystem responses to global change and support applied and policy-oriented processes related to environmental management. Examples of specific applications are:
Based on hydro-climatological observation network running at a national scale since the 1990s, an Atlas is published annually to document and report on the climatic conditions and water resources across Luxembourg. The Atlas is published together with the Administration de la gestion de l’eau (AGE)and the Administration des services techniques de l'agriculture (ASTA).
HOST handles essential datasets that integrate hydrological, meteorological and geomorphic processes from plot to watershed scales across Luxembourg. This LIST environmental database is one of the largest collection of data on hydro-climatological conditions in Luxembourg. The data are robust in scale and scope and are transformed into a harmonised dataset to support researchers in their studies on environmental conditions. LIST researchers and other stakeholders can access the data through a data use request form.
