Sentinel-5P TROPOMI – Sulfur dioxide (SO2), Level 3 – Global

The TROPOMI instrument onboard the Copernicus SENTINEL-5 Precursor satellite is a nadir-viewing, imaging spectrometer that provides global measurements of atmospheric properties and constituents on a daily basis. It is contributing to monitoring air quality and climate, providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the top of atmosphere solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum. The operational trace gas products generated at DLR on behave ESA are: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4), together with clouds and aerosol properties. This product displays the sulphur dioxide (SO2) concentration around the globe. Sulphur dioxide enters the atmosphere through volcanic eruptions and human-related activities. Daily observations are binned onto a regular latitude-longitude grid. This product is created in the scope of the project INPULS. The DLR INPULS project develops (a) innovative retrieval algorithms and processors for the generation of value-added products from the atmospheric Copernicus missions Sentinel-5 Precursor, Sentinel-4, and Sentinel-5, (b) cloud-based (re)processing systems, (c) improved data discovery and access technologies as well as server-side analytics for the users, and (d) data visualization services.

Multibeam bathymetry processed data (EM 1002 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM62/2

Swath sonar bathymetry data used for that dataset was recorded during RV MARIA S. MERIAN cruise MSM62/2 using Kongsberg EM1002 multibeam echosounder. The cruise took place between 23.03.2017 and 27.03.2017 in the Baltic Sea. The cruise aimed to investigate the impact of the Littorina transgression on the inflow of saline waters into the western Baltic and assessed the potential for future diminution of ventilation in the central and northern deeper basins due to isostatic uplift [CSR]. CI Citation: Paul Wintersteller (seafloor-imaging@marum.de) as responsible party for bathymetry raw data ingest and approval. During the MSM62/2 cruise, the moonpooled KONGSBERG EM1002 multibeam echosounder (MBES) was utilized to perform bathymetric mapping in shallow depths. The echosounder has a curved transducer in which 111 beams are formed for each ping while the seafloor is detected using amplitude and phase information for each beam sounding. For further information on the system, consult https://www.km.kongsberg.com/. Postprocessing and products were conducted by the Seafloor-Imaging & Mapping group of MARUM/FB5, responsible person Paul Wintersteller (seafloor-imaging@marum.de). The open source software MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, https://www.mbari.org/products/research-software/mb-system, 2017) was utilized for this purpose. A sound velocity correction profile was applied to the MSM62/2 data; there were no further corrections for roll, pitch and heave applied during postprocessing. A tide correction was applied, based on the Oregon State University (OSU) tidal prediction software (OTPS) that is retrievable through MB-System. CTD measurements during the cruise were sufficient to represent the changes in the sound velocity throughout the study area. Using Mbeditviz, artefacts were cleaned manually. NetCDF (GMT) grids of the edited data as well as statistics were created with mbgrid. The published bathymetric EM1002 grid of the cruise MSM62/2 has a resolution of 15 m. No total propagated uncertainty (TPU) has been calculated to gather vertical or horizontal accuracy. A higher resolution is, at least partly, achievable. The grid extended with _num represents a raster dataset with the statistical number of beams/depths taken into account to create the depth of the cell. The extended _sd -grid contains the standard deviation for each cell. The DTMs projections are given in Geographic coordinate system Lat/Lon; Geodetic Datum: WGS84.

Multibeam bathymetry processed data (EM 1002 echosounder entire dataset) of RV MARIA S. MERIAN during cruise MSM51/1

Swath sonar bathymetry data used for that dataset was recorded during RV MARIA S. MERIAN cruise MSM51/1 using Kongsberg EM1002 multibeam echosounder. The cruise took place between 01.02.2016 and 27.02.2016 in the Baltic Sea. The cruise aimed to perform seismo- and hydroacoustic surveys, sampling of Holocene sediments and to investigate the water column wintertime mixing close to sea-ice limits. These surveys improved the understanding of variations in the ventilation of the deeper Baltic, considering not only external climate forcing but also the effects of postglacial sealevel rise and isostatic uplift [CSR].

Open Circular-Collaboration-Platform for Sustainable Food Packaging from Plastics

Das Projekt "Open Circular-Collaboration-Platform for Sustainable Food Packaging from Plastics" wird/wurde ausgeführt durch: SKZ - KFE gGmbH.Various informational and market conditions, whose development can be traced back to a linear economy, currently also prevent an increased closing of the loop as well as the reduction of material use in the application case of plastic packaging for food. The project objective of COPPA is therefore to develop and demonstrate an open and scalable Circular Collaboration Platform (CCP) that creates the following functionalities for recyclers, plastic reprocessors / converters, packaging manufacturers and food retailers: · Establishing seamless tracking of plastics · Enabling a better exchange of information for automated quality proof, prediction of availability, etc. · Proof of recycled content and recycled quality of products and material batches · Proof of origin or owner as a dynamised property per batch/ main ingredient. · Development of a smart contract model for value chains - in the sense of democratised and notarised plastics processing. · Provision of decision-making aids for the reduction of packaging material and the use of recycled material as a conceptual approach or as a control instrument (dashboard) · Precise verification of sustainability effects through reduced material consumption and increased use of recycled materials (CO2 or resource savings according to relevant material groups). With the aim of enabling both material savings and an increased recycled content in plastic packaging through networking, control and tracking, the CCP is to bring together digital solution approaches as a system solution; in accordance with the FAIR principles, data should be 'Findable, Accessible, Interoperable, and Re-usable'. The project result should represent a practical demonstrator (Technology Readiness Level 5-6), which at the end of the implementation phase will be accessible to all companies in the entire food chain in a non-discriminatory and freely available manner.

Glacial landforms around the boundary between the central and northern Black Forest, south-western Germany

The aim of data collection was the reconstruction of the chronology and extent of the Late Pleistocene glaciation around the boundary between the central and northern Black Forest. This research has been undertaken as part of the 'Chronology of the last glaciation of low mountainous areas in Central Europe' project (funded by the German Research Foundation (DFG)). This project is granted to Felix Martin Hofmann (see https://gepris.dfg.de/gepris/projekt/534739108?language=en, last access: 13 June 2025). As a first step towards comprehensive glacier reconstruction, glacial geomorphological mapping according to present-day standard in the field of glacial geomorphology must be undertaken, allowing for the selection of suitable targets for dating campaigns. Previous cirque and moraine mapping led to valuable datasets but the adopted approach for the acquisition of data does not comply with up-to-date approaches in geomorphological mapping. Hence, a mapping campaign was undertaken to critically evaluate previous work on the region of interest to achieve the greatest possible accuracy during mapping. The acquired data represent the base of a manuscript which has been submitted to the Journal of Geomorphology for consideration for publication.

Senckenberg Dogger Bank Monitoring Data_Amphipoda_2024

This dataset presents newly collected records of amphipod specimens gathered during the 2024 scientific benthic survey (Cruise DOG24) at the Dogger Bank, North Sea, part of an ongoing annual monitoring effort that has taken place from 1991 to 2024. A total of 8,444 specimens of 14 species belonging to 13 families, 14 genera, and 10 species were identified using morphological methods with Leica M60 and DM750 microscopes. Amphipods, key components of marine benthic ecosystems, were sampled by beam trawl over the Dogger Bank’s stable sandy substrate. This dataset supports a broader research project aimed at (i) developing a taxonomic key for Dogger Bank amphipods, (ii) identifying environmental drivers of species distribution and diversity, and (iii) predicting responses to climate change. Data were structured following the Darwin Core standard. The Dogger Bank epibenthos is sampled with a 2 m beam trawl at 37 stations on a yearly basis since 1991 by Senckenberg Marine Zoology. At each station, the catch is sieved to preserve the fine fraction (1 cm - 1 mm), while megafaunal animals are sorted, identified and recorded by their abundance on board of RV Senckenberg. The crustacean and Ichthyology collections at Senckenberg Marine Zoology house the fine fractions from these cruises. In this project, we aim to identify the amphipod species composition and relative abundance from these fine fractions. Starting with the analysis of the fine fractions from the year 2024, we will step by step enhance the dataset with identifications of amphipod fine fractions from other years, back until 1991.

FP4-NNE-THERMIE C, Variable speed technology for low heat hydropower systems

Das Projekt "FP4-NNE-THERMIE C, Variable speed technology for low heat hydropower systems" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Universität Kassel, Fachbereich 16 - Elektrotechnik,Informatik, Institut für Elektrische Energietechnik, Rationelle Energiewandlung.Objective: Aim is to modify two small hydropower plants to variable speed operation in order to increase annual energy output by improved part load efficiency and design flow. A 100 kW vertical axis Francis turbine (Kaltenburg, DE) and a new 18 kW waterwheel (Bettborn, LU) will be modified to variable speed operation by use of a AC-AC converter. There will be installed a movable free-overfall weir at the waterwheel. By an expected increase of the electricity production in the range of 10 to 20 per cent , the aim is to proof viability of improving existing low head hydro sites with this technology. Especially low head sites have high variation of head and flow. Variable speed technology allows the system to operate at maximum efficiency for a wide range of hydraulic conditions. Modern power electronics replaces complex mechanical control systems with a high need for maintenance. In wind energy, variable speed technology has already proven its advantages compared to other mechanical technologies. General Information: Unlike earlier approaches with a combination of double regulated turbines and variable speed in a new installation, in this project the combination of a Francis turbine (respectively a water wheel) in existing plants together with a frequency converter will be used to increase part load efficiency and design flow of the system. Only the new IGBT controlled converters which are now used in wind energy as well as in motive power industry appliances can guarantee a reliable variable speed operation of a normal asynchronous generator. The combination of the movable weir and variable speed operation of the water wheel will allow to optimise the power output of the plant under all conditions. The use of an IGBT converter makes it possible to compensate reactive power to improve the mains performance. Due to detailed theoretical analysis and according to the positive experience with variable speed operation in wind energy and motive power technology, the expected increase of the annual power output of the two plants is in the range of 10 to 20 per cent of the actual value. This will reduce the specific cost of the electricity by the same range. For the actual payback tariffs of many European countries, this will increase the number of feasible low head sites. The top water level control by variation of turbine speed (and so flow) will be demonstrated to show a simple, reliable and energy saving alternative to the old hydraulic systems, which are still installed in many sites. The success of the variable speed system in this plants will open a big European SME market for cheap technological improvement of small hydropower plants and low head sites. The monitored performance of the plants data will be stored in a data logger with a modem, to allow automatic down-loading from a server-PC via modem. ...
