METOP GOME-2 - Formaldehyde (HCHO) - Global

The Global Ozone Monitoring Experiment-2 (GOME-2) instrument continues the long-term monitoring of atmospheric trace gas constituents started with GOME / ERS-2 and SCIAMACHY / Envisat. Currently, there are three GOME-2 instruments operating on board EUMETSAT's Meteorological Operational satellites MetOp-A, -B, and -C, launched in October 2006, September 2012, and November 2018, respectively. GOME-2 can measure a range of atmospheric trace constituents, with the emphasis on global ozone distributions. Furthermore, cloud properties and intensities of ultraviolet radiation are retrieved. These data are crucial for monitoring the atmospheric composition and the detection of pollutants. DLR generates operational GOME-2 / MetOp level 2 products in the framework of EUMETSAT's Satellite Application Facility on Atmospheric Chemistry Monitoring (AC-SAF). GOME-2 near-real-time products are available already two hours after sensing. The operational HCHO total column products are generated using the algorithm GDP (GOME Data Processor) version 4.x integrated into the UPAS (Universal Processor for UV / VIS Atmospheric Spectrometers) processor for generating level 2 trace gas and cloud products. For more details please refer to relevant peer-review papers listed on the GOME and GOME-2 documentation pages: https://atmos.eoc.dlr.de/app/docs/

Dauerbeobachtung der Vegetationsentwicklung und Grundwasserqualitaet in geschuetzten Feuchtgebieten von Rheinland-Pfalz (Reg.-Bez. Trier)

Das Forschungsvorhaben soll dazu beitragen zu klaeren, welchen Veraenderungen die Vegetation von unter Schutz stehenden Feuchtgebieten langfristig unterliegt (ungelenkte Sukzession). Zur Klaerung moeglicher Ursachen werden die Nutzungsgeschichte, Daten der naechstgelegenen Klima- und Luftimmissionsstationen, die chemische Zusammensetzung regelmaessig entnommener Quell- und Grundwasserproben sowie die Naehrstoffvorraete im Boden ausgewertet. Die Vegetation wird in 3-5jaehrigen Abstaenden auf 2 x 2 m grossen Teilflaechen entlang von 50-100 m langen Beobachtungstransekten dokumentiert. Insgesamt werden 5 vermoorte Maare der Vulkaneifel, 5 waldfreie und 8 locker bewaldete Quellmoore des Hunsrueck und der Schneifel untersucht. Erste Ergebnisse zeigen den starken Einfluss von Klimaschwankungen, sekundaere Sukzessionsprozesse nach Nutzungsaufgabe sowie Wirkungen anthropogener Stoffeintraege (Versauerung, Eutrophierung).

Continuous recordings of environmental parameters at station 4, Westermakelsdorf (2019-09 - 2024-03)

Additionally, at four shallow water stations (Booknis Eck, Buelk, Behrensdorf and Katharinenhof) temperature, salinity and dissolved oxygen are continuously logged at 2-3 m depth by self-contained data loggers. These are: (I) MiniDOT loggers (Precision Measurement Engineering; http://pme.com; ±10 µmol L-1 or ±5 % saturation) including copper antifouling option (copper plate and mesh) to measure dissolved oxygen concentration and (II) DST CT salinity & temperature loggers (Star-Oddi; http://star-oddi.com; ±1.5 mS cm-1) to record the conductivity. Both sensor types additionally record water temperature with an accuracy of ± 0.1 °C. The sampling interval was set to 30 minutes for all parameters. In context of the long-term monitoring project RegLocDiv (Regional-Local-Diversity) by M. Wahl (Franz, M. et al. 2019a), another seven stations were equipped with the same two types of sensors at 4-6 m depth to continuously record environmental parameters (again: temperature, salinity, dissolved oxygen) and included into this data set. These stations are at: Falshoeft, Booknis Eck, Schoenberg, Westermarkelsdorf, Staberhuk, Kellenhusen and Salzhaff (abandoned in 2023). Since 2021, in the context of implementing a reef monitoring to fulfil obligations by the EU Habitats Directive, step-by-step, eleven further stations were installed at reefs in the Schleswig-Holstein Baltic Sea. These are at: Platengrund (14 m depth) and Mittelgrund (8 m) (both since 2021), at Walkyriengrund (9 m), Brodtener Ufer (8 m), Außenschlei (11 m), Kalkgrund (8 m), Stollergrund (7.5 m) and Flueggesand (10 m) (all since 2022), as well as at Gabelsflach (10 m), Sagasbank (8.5 m) and Stabehuk (11.5 m) (all since 2023). Again, at all of these 11 stations, temperature, salinity and dissolved oxygen are continuously logged by self-contained data loggers: Conductivity (and temperature) is logged by HOBO® Salt Water Conductivity/Salinity Data Logger (Onset Computer Corporation, Bourne, MA, USA; https://www.onsetcomp.com) using the U2X protective housing to prevent fouling on the sensors. The same MiniDOT loggers (Precision Measurement Engineering) as at the above mentioned more shallow stations (including antifouling copper plate and mesh) are used to measure dissolved oxygen concentration. Dissolved oxygen concentration data measured by the MiniDOT loggers are corrected for a depth of 10 m (or 2,5 m on the shallow stations) using the software provided by the manufacturer. Additionally, a manual compensation for salinity was calculated (see details in Franz, M. et al. 2019b). Quality control was carried out by spike and gradient tests, following recommendations of SeaDataNet quality control procedures (see https://seadatanet.org/Standards/Data-Quality-Control). All data values were flagged according to applied quality checks using the following flags: 1 = Pass, 2 = Suspect, 3 = Fail, 4 = Visually suspect, 5 = Salinity compensation fail (further explanations can be found in Franz, M. et al. 2019b).

Langzeitmonitoring und Funktionalität von Staubabscheidern für Einzelraumfeuerungen im Feld

Das Vorhaben 'LangEFeld' zielt auf ein Langzeit-Monitoring von Elektroabscheidern im Feld an Kleinfeuerungsanlagen wie dem Pellet- und Kaminofen ab. Hierbei soll es um die Verfügbarkeit und mögliche Alterungseffekte der Elektroabscheider im Feld gehen und die Abscheideeffizienz vor und nach dem Feldversuch werden ermittelt. Für die Beurteilung der Abscheidegrade sind geeignete Messverfahren zu suchen. Außerdem werden verschiedene Messmethoden zur Bestimmung der Partikelanzahl und Partikelgrößenverteilung in Prüfständen vor und nach dem Abscheider miteinander verglichen. Daraus sollen Empfehlungen an die Praxis hinsichtlich der Betriebssicherheit und der Vermeidung von Fehlbedienungen abgeleitet werden. Gleichzeitig werden auch die Grundlagen erarbeitet, um zukünftig effektive Staubminderungsmaßnahmen entwickeln zu können sowie wirkungsvolle Benutzerregeln und Fördermaßnahmen für solche nachrüstbaren Komponenten ableiten zu können. Neben den Elektroabscheidern gibt es auch vielversprechende Katalysatorlösungen als integrierte Emissionsminderungsmaßnahme, die jedoch bisher keinen Langzeittests ausgesetzt wurden, weshalb momentan noch keine belastbaren Aussagen zu Standzeiten von Katalysatoren in Einzelraumfeuerungen getroffen werden können. Damit werden die im Projekt ohnehin erforderlichen Datenerfassungen und Dokumentationen an den Praxisanlagen zusätzlich dazu verwendet, die Einsatzbedingungen bei der gezielt herbeigeführten Katalysatoralterung über längere Betriebszeiten zu charakterisieren.

Forstliche Versuchsflächen des Landes Brandenburg (WMS gesamt)

Das Landeskompetenzzentrum Forst Eberswalde verwaltet Daten von fast 1000 im ganzen Land Brandenburg verteilten Versuchen mit über 3000 häufig sehr langfristig bearbeiteter Einzelflächen (teilweise seit 1870), von denen mehr als 1000 Flächen noch unter aktueller Beobachtung stehen. Die Digitalisierung der Lageskizzen älterer Flächen erfolgte 2013-2014. Neue Flächen werden mit Hilfe von GPS geografisch verortet. Die Daten werden in einer Datenbank der langfristigen forstlichen Versuchsflächen des Landes Brandenburg verwaltet.
