Das Messnetz "Bodenwasserhaushalt" dient der kontinuierlichen Erfassung der Interaktion zwischen Witterung, Bewuchs und Bodenwasserhaushalt. Es umfasst 21 wägbare Lysimeter mit natürlichen Ackerböden, 5 wägbare Lysimeter mit Böden von der Kippe der ehemaligen Tagebaue Espenhain und Witznitz sowie 2 nichtwägbare Lysimeter im Forst Naunhof. Desweiteren werden am Standort Brandis unterschiedliche Niederschlagsmesser, eine Klimastation und Bulksammler (zur Messung der Gesamtdeposition) betrieben. Die Datenerfassung sowie -auswertung erfolgt derzeit ausschließlich in der UBG (GB3). Arbeitsschwerpunkte der Auswertung sind: - Transport- und Umsatzprozesse in der ungesättigten Zone - Auswirkung von landwirtschaftlichen Bewirtschaftungsstrategien auf die GW-Beschaffenheit - Klimawandel und Bodenwasserhaushalt - Bereitstellung der Daten für Simulationsmodelle WH-Verfahren.
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.

Nahrungserwerb der Waldameisen in einem Eichenwald im Tages- und Jahresverlauf, Jahresbilanz (Menge, Zusammensetzung, Energiegehalt der Nahrung). Beeinflussung des Nahrungserwerbs durch Umweltfaktoren (Witterung, Nahrungsangebot). Regulation des Nahrungserwerbs durch die Waldameisen selbst. Einfluss der Waldameisen auf den Massenwechsel eines Schadinsekts (Eichenwickler Tortrix viridana L.).
Der Waermehaushalt der trockenfallenden Wattflaechen und der Wasserflaechen wird untersucht. Waermestroeme im Boden und Temperaturaenderungen des Wassers werden zusammen mit den meteorologischen Einflussgroessen an 4 Stationen registriert. Daraus laesst sich die Reichweite der Auswirkungen von Kuehlwassereinleitungen angeben, als Grundlage fuer biologische und klimatische Untersuchungen. Veraenderung der Temperaturverhaeltnisse im Wasser und Wattboden durch Kuehlwassereinleitungen. Die Arbeiten laufen im Rahmen des Umweltprogramms - Ueberwachung der Kuestengewaesser - der Bundesregierung. Profilmessungen unter verschiedenen Tide- und Witterungsbedingungen werden vom Schiff aus durchgefuehrt um die Dauerregistrierungen zu unterstuetzen bzw. zu ergaenzen.
Erstmalig wird im Rahmen einer internationalen Arbeitsgemeinschaft fuer Bodenfruchtbarkeit der Internationalen Bodenkundlichen Gesellschaft eine vergleichende Versuchsreihe mit einer Fruchtfolge sowie mit Kombination von organischer Duengung und mineralischer Duengung bei Abstufung der Stickstoffduengung in 6 Stufen durchgefuehrt. Parallel laufen Bodenuntersuchungen sowie Pflanzenuntersuchungen und die Erfassung der Witterungsdaten. Besondere Arbeitsgruppen befassen sich mit: dem Stickstoffhaushalt im Boden, den Ertragsanalysen einschliesslich Entwicklungsphysiologie, der Qualitaetsuntersuchung sowie der biometrischen Auswertung. Zur Zeit sind 23 Standorte in 9 Laendern Europas beteiligt.

GOME-2 near-real-time products are available already two hours after sensing. The operational SO2 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. GDP 4.x performs a DOAS fit for SO2 slant column followed by an AMF / VCD computation using a single wavelength. Corrections are applied to the slant column for equatorial offset, interference of SO2 and SO2 absorption, and SZA dependence.

The operational NO2 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. The operational NO2 tropospheric column products are generated using the algorithm GDP (GOME Data Processor) version 4.x for NO2 [Valks et al. (2011)] integrated into the UPAS (Universal Processor for UV / VIS Atmospheric Spectrometers) processor for generating level 2 trace gas and cloud products. The total NO2 column is retrieved from GOME solar back-scattered measurements in the visible wavelength region using the DOAS method. An additional algorithm is applied to derive the tropospheric NO2 column: after subtracting the estimated stratospheric component from the total column, the tropospheric NO2 column is determined using an air mass factor based on monthly climatological NO2 profiles from the MOZART-2 model.
