In accordance with European legislation, the Environment Agency has updated the strategic noise maps for the fourth cycle of Directive 2002/49/EC of the European Parliament and of the Council of 25 June 2002 relating to the assessment and management of environmental noise. These maps refer to the year 2023 and indicate, with the help of a standardised colour scale using the Lden indicator, the exposure to ambient noise in decibels of the major airports per year located on the territory of the Grand Duchy of Luxembourg. The indicators used to describe the annoyance caused by exposure to noise are : Lden in decibels (dB), a representative average noise indicator for a 24-hour day, evaluated over a full year and for which the evening period is penalised by 5 dB(A) and the night period is penalised by 10 dB(A); and the Lnight in decibels (dB), a representative average noise indicator for an 8-hour night, assessed over a full year and associated with sleep disturbance. The indicators are based on three periods of the day: a day" period of 12 hours (7am to 7pm), an "evening" period of 4 hours (7pm to 11pm) and a "night" period of 8 hours (11pm to 7am)."

Dieser Layer enthält den CDI (combined drought index), der auf Basis von Satellitendaten ermittelt wurde. Weitere Informationen : Abschlussbericht. Kurzfassung (Synthese)

This layer contains all establishments (here generally referenced as "POI") that are listed in the national commercial cadastre ("Cadastre du commerce" and are regularly updated there. This Layer provides a complete overview of all retail and Horeca businesses and, with some restrictions, all service businesses. In the present layer, the establishments are presented differentiated according to their respective main industry ("branche principale" (fr)).

Layer description: This data is part of the climate analysis map of Luxembourg. Shown is the cold air volume flow density (4 a.m.) in the area of green and open spaces of Luxembourg. Explanation: The present geodata are taken from the regional climate analysis of Luxembourg (GEO-NET & LIST 2021) which was published with the report « KLIMAÖKOLOGISCHE SITUATION IN LUXEMBURG“ - Modellbasierte regionale Klimaanalyse / (La situation au Luxembourg en matière d’écologie climatique) » by the Administration for Environment.

In total, the model area is described with 8,272,693 grid cells, with information on terrain height, land use, structural height and degree of sealing stored for each grid cell. The urban climate model FITNAH-3D according to Groß (1992) forms the basic framework for the modelling. The input data and model results are based on a horizontal spatial resolution of 25 m x 25 m. The model results are presented in maps. The model results are presented in cartographic representations of the nocturnal temperature field, the nocturnal cold air flow field (4 a.m. in each case) and the thermal load during the day (2 p.m.) and concretised in the form of a climate analysis map. The main product of the work process is a planning recommendation map with an associated catalogue of measures. On the one hand, the map makes visible the graduated need for action to improve thermal comfort in summer in all living/working and recreational areas (“load area”) of the population in Luxembourg. On the other hand, the planning recommendation map also assigns a value to all green and open spaces in the country ("compensation area") with regard to the climate-ecological functions they provide. Notes: - The geodata are only to be used in the context of the specific considerations of the above-mentioned report (e.g.: basic data as of 2018, specific meteorological framework conditions). - The composition of the layers is based on the corresponding maps from the above-mentioned report. Even though these layers can be combined with any other layers from other thematic areas in the geoportal, it should be noted that these representations can easily lead to misinterpretations.

Layer description: This data is part of the climate analysis map of Luxembourg. Shown is the special function of (potentially) public green spaces and forests. Due to their effect as a cooling island during the day, forests are of particular climatic-ecological importance even if they are not part of a cold air system at night. Furthermore, public green spaces can serve as important retreats for the population, especially during the day. If possible, publicly accessible green spaces should have a high level of microclimate diversity and/or a high proportion of trees so that they can develop their bioclimatic favourable effect during the day in the best possible way.

Layer description: Cold air exchange areas occur extensively over undeveloped areas, especially on slopes, and are oriented towards the settlement area. They are characterised by a near-ground flow velocity of mostly over 0.3 m/s or an above-average cold air volume flow density of over 16 m³/(s*m). Thus, they fulfil the same criteria as the cold-air corridors, but are not limited in width by adjacent structures (e.g. buildings or forests).

Ce projet avait pour but de convertir des indices de bruit pour un nombre d'exemples de bruit industriel. Des mesurages de 5 cinq établissements ont été réalisés sur une durée de 1 à deux semaines. Il est à noter que certains bruits de fond externes au fonctionnement des établissements peuvent être présents: *Ecotec : la lecture est directe en journée. La nuit la société ne fonctionne pas, seuls quelques trains de marchandises circulent à l’arrière. *Dupont de Nemours : La lecture des résultats est directe pas besoin de corriger les données. *ArcelorMittal ; les données sont brutes. Elles sont influencées par des sources sonores extérieures à l’établissement. Au Nord, elles sont influencées par le trafic routier. Au Sud, elles sont influencées par la cloche de l’église en période jour. La nuit, les résultat sont directs. Avant l'utilisation des données veuillez contacter Olivier Schwab pour discuter les détails et les limitations des mesurages.

This layer contains the Auto-Pédestre circular trails.

According to Articles 6 to 14 of Directive 2008/50/EC of the European Parliament and of the Council (15), the two following areas have been defined for Luxembourg: (1) One area, called here “Active”, groups historical LCPU and CES districts as well as all cities where a high urbanization degree (1 or 2) and cities with a lower degree but which are surrounded by cities with a higher degree and impacted by traffic. Some cities from the border of the country (Germany/Luxembourg) filling these criteria have also been considered. Isolated cities of the urbanization map belonging to the same district and located between cities with high level of urbanization and showing high level of traffic have also been included in the Active area. (2) The second area, called “Rural” represents the area of the country where the traffic, the density of inhabitants and the number of industries are low. The total number of inhabitants of this area would be 151097 for 2021.
