Vertikale Verteilung von Wolkenkondensationskernen in marinen und kontinentalen Luftmassen in Europa und ihre Verbindung zur Wolkentropfenanzahlkonzentration in warmen Wolken

Die Anzahl der verfügbaren Wolkenkondensationskerne (CCN) beeinflusst maßgeblich die mikrophysikalischen Wolkeneigenschaften, wie z.B. die Wolkentropfenanzahlkonzentration (CDNC) und deren Größenverteilung. CDNC und die Tropfengröße steuern sowohl die Strahlungseigenschaften als auch die Lebensdauer von Wolken. Dies wirkt sich komplex auf die Energiebilanz der Erde aus. Aktuelle Klimamodelle basieren häufig auf Annahmen über CCN Anzahlkonzentrationen und andere CCN bezogene Eigenschaften (z.B. Hygroskopizität), da für viele Regionen auf der Erde repräsentative Daten fehlen. Wenn vorhanden, handelt es sich bei diesen CCN Daten um bodengebundene Messungen, welche somit nicht - mit Ausnahme von Bergstationen - in der für Wolkenbildungsprozesse relevanten Höhe durchgeführt wurden. Für die Karibikregion wurde gezeigt, dass die bodengebundenen CCN Messungen für die gesamte marine Grenzschicht repräsentativ zu sein scheinen also auch für die Wolkenbildungsregionen. Im hier vorgeschlagenen Projekt wollen wir überprüfen, ob bodengebundene CCN Messungen auch in anderen Erdregionen repräsentativ sind für die CCN Anzahl in der Wolkenbildungsregion, und wenn ja, unter welchen Bedingungen. Dies würde die Anwendung von CCN Daten in Modellen stark vereinfachen. Dazu wird die Gültigkeit der Beobachtungen in der Karibik, in zwei gegensätzlichen Umgebungen getestet werden, einmal in einer marinen und einmal in einer kontinentalen Umgebung. Die Messkampagne zu marinen CCN soll auf den Azoren (Portugal) durchgeführt werden. Wir werden kontinuierlich verfügbare CCN Daten von der Azoren Eastern Nordatlantik (ENA) Station auf der Insel La Graciosa (auf Meereshöhe) mit Daten von der Bergstation Pico (Pico Island, 2225 m ü.d.M.) kombinieren. Ergänzend werden CCN und CDNC Messungen auf der Helikopter-Messplattform (ACTOS) durchgeführt, um die vertikale Lücke zwischen den Meeresspiegel- und Bergmessungen zu schließen. Die kontinentalen bodengebundenen CCN Messungen werden kontinuierlich an der ACTRIS Station Melpitz durchgeführt. Die vertikale CCN und CDNC Verteilung wird in Melpitz mit Hilfe eines Ballons in mehreren einwöchigen Kampagnen einmal pro Jahreszeit gemessen werden. Darüber hinaus werden wir mit Hilfe der Aerosol-Wolken-Wechselwirkungsmetrik (ACI) die in der Wolke in-situ gemessen CCN Eigenschaften (das heißt Anzahl und Hygroskopizität) mit den CDNC quantitativ verbinden. Es wird außerdem eine Sensitivitätsstudie mit einem Cloud-Parcel Model durchgeführt, welches durch die realen Messungen in der Atmosphäre angetrieben werden wird. Dies wird einen Einblick in das Übersättigungsregime von frisch gebildeten Wolken gewähren.Die CCN Daten selbst, die Erkenntnisse zu CCN Eigenschaften und ihrer vertikalen Verteilung sowie die quantitative Verbindung zwischen CCN und CDNC werden im Hinblick auf das Verständnis und die Modellierung der Wolkentropfenaktivierung sowie der mikrophysikalischen Wolkeneigenschaften von außerordentlichem Wert sein.

Member States' greenhouse gas (GHG) emission projections

The Governance of the Energy Union and Climate Action ((EU) 2018/1999) requires Member States to report national projections of anthropogenic GHG emissions. Every two years, each EU Member State shall report GHG projections in a ‘with existing measures’ scenario for the years 2020, 2025, 2030, 2035, 2040, 2045 and 2050 by gas (or group of gases) and by sector. National projections shall take into consideration any policies and measures adopted at Union level. The reported data are quality checked by the EEA and its European Topic Centre for Climate Change Mitigation and Energy (ETC/CME).

NECPR: Progress to targets for greenhouse gas emissions and removals (Annex I) dataset, 2023

Progress to targets for greenhouse gas (GHG) emissions and removals is a dataset under the National Energy and Climate Progress Reports (NECPRs), which is reported every second year (starting in 2023) by EU Member States. The dataset provides information regarding Member State's GHG and removals targets and progress in achieving them. The EEA collects and quality checks this data. The dataset links to data from GHG inventories and projections (also collected by the EEA), as well as Annual Emission Allocations (AEAs). This reporting obligation comes from the Governance Regulation 2018/1999, Implementing Regulation (EU) 2022/2299 (Annex I).

National emissions reported to the Convention on Long-range Transboundary Air Pollution (LRTAP Convention)

Data compiled are annual national total and sectoral emissions of air pollutants and associated activity data reported by EEA member and cooperating countries. Data are available for download in the UNECE/EMEP Nomenclature for Reporting (NFR) format used by countries. A consolidated dataset for all countries and consistent with the European Union's air pollutant emission inventory submission to the LRTAP Convention is also provided.

EEA basemap

This Discomap web map service provides an EU-27 (2020) basemap for internal EEA use as a background layer in viewers or any other web application. It is provided as REST and as OGC WMS services, dynamic and cached. The cached service has a custom cache at the following scales: 1/50.000.000 1/42.000.000 1/36.000.000 (Europe's size) 1/30.000.000 1/20.000.000 1/10.000.000 1/5.000.000 1/2.500.000 1/1.000.000.

EEA Reference grid

The grid is based on the recommendation at the 1st European Workshop on Reference Grids in 2003 and later INSPIRE geographical grid systems. For each country three vector polygon grid shape files, 1, 10 and 100 km, are available. The grids cover at least country borders - plus 15km buffer - and, where applicable, marine Exclusive Economic Zones v7.0 - plus 15km buffer - (www.vliz.be/vmdcdata/marbound). Note that the extent of the grid into the marine area does not reflect the extent of the territorial waters.

Population trend of bird species: datasets from Article 12, Birds Directive 2009/147/EC reporting (2013-2018) - INTERNAL VERSION - Oct. 2020

All EU Member States are requested to monitor birds listed in the Birds Directive (2009/147/EC) and send a report about the progress made with the implementation of the Directive every 6 years following an agreed format. The assessment of breeding population short-term trend at the level of country is here presented. The spatial dataset contains gridded birds distribution data (10 km grid cells) as reported by EU Member States for the 2013-2018 period. The dataset is aggregated by species code and country in the attribute CO_MS. By use of the aggregated attribute [CO_MS], the tabular data can be joined to the spatial data to obtain e.g. the EU population status and trend. This metadata refers to the INTERNAL dataset as it includes species flagged as sensitive by Member States. Therefore, its access is restricted to only internal use by EEA.
