Vulnerability and Resilience of Soils under Different Rangeland Use

This project aims to elucidate how sensitive and to which extent soil properties respond to different rangeland management in the grassland and savannah biome of semiarid South Africa, and to figure out to which degree changes of the ecosystems are perceived and caused by farmers' decisions. We hypothesise that both ecosystems respond differently to rangeland degradation: in the savannah biome bush encroachment leads to an improvement of the soil quality, whereas in grasslands degradation of the soils proceeds with intensified management.

Sentinel-5P TROPOMI – Cloud Optical Thickness (COT), Level 3 – Global

This product displays the Cloud Optical Thickness (COT) around the globe. Clouds play a crucial role in the Earth's climate system and have significant effects on trace gas retrievals. The cloud optical thickness is retrieved from the O2-A band using the ROCINN algorithm. The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers. The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) 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, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4). Within the INPULS project, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.

Sentinel-5P TROPOMI – Ozone (O3), Level 3 – Global

Ozone vertical column density in Dobson Units as derived from Sentinel-5P/TROPOMI observations. The stratospheric ozone layer protects the biosphere from harmful solar ultraviolet radiation. Ozone in troposphere can pose risks to the health of humans, animals, and vegetation.

Sentinel-5P TROPOMI – Cloud-Top Height (CTH), Level 3 – Global

Global Cloud-Top Height (CTH) as derived from the Sentinel-5P/TROPOMI instrument. Clouds play a crucial role in the Earth's climate system and have significant effects on trace gas retrievals. The cloud-top height is retrieved from the O2-A band using the ROCINN algorithm. Daily observations are binned onto a regular latitude-longitude grid.

WMS SL Digitale Geländemodelle - Shaded Relief (2025)

Digitale Geländemodelle (DGM) sind digitale, numerische, auf ein regelmäßiges Raster reduzierte Modelle der Geländehöhen und –formen der Erdoberfläche. Sie beinhalten keine Information über Bauwerke (z.B. Brücken) und Vegetation.:Das Shaded Relief DGM wurde aus den aktuellen Laser-Daten abgeleitet. Hierbei handelt es sich um eine maßstäbliche, dreidimensional-physikalische Nachbildung des Saarlandes mit Hervorhebung des Geländes. Es wurde keine Überhöhung vorgenommen, welche dazu genutzt werden kann um die charakteristischen Oberflächenformen des dargestellten Gebietes leichter wahrnehmen zu können.

Tree Species - Sentinel-1/2 - Germany, 2022

The Tree Species Germany product provides a map of dominant tree species across Germany for the year 2022 at a spatial resolution of 10 meters. The map depicts the distribution of ten tree species groups derived from multi-temporal optical Sentinel-2 data, radar data from Sentinel-1, and a digital elevation model. The input features explicitly incorporate phenological information to capture seasonal vegetation dynamics relevant for species discrimination. A total of over 80,000 training and test samples were compiled from publicly accessible sources, including urban tree inventories, Google Earth Pro, Google Street View, and field observations. The final classification was generated using an XGBoost machine learning algorithm. The Tree Species Germany product achieves an overall F1-score of 0.89. For the dominant species pine, spruce, beech, and oak, class-wise F1-scores range from 0.76 to 0.98, while F1-scores for other widespread species such as birch, alder, larch, Douglas fir, and fir range from 0.88 to 0.96. The product provides a consistent, high-resolution, and up-to-date representation of tree species distribution across Germany. Its transferable, cost-efficient, and repeatable methodology enables reliable large-scale forest monitoring and offers a valuable basis for assessing spatial patterns and temporal changes in forest composition in the context of ongoing climatic and environmental dynamics.

CropTypes - Crop Type Maps for Germany - Yearly, 10m

This raster dataset shows the main type of crop grown on each field in Germany each year. Crop types and crop rotation are of great economic importance and have a strong influence on the functions of arable land and ecology. Information on the crops grown is therefore important for many environmental and agricultural policy issues. With the help of satellite remote sensing, the crops grown can be recorded uniformly for whole Germany. Based on Sentinel-1 and Sentinel-2 time series as well as LPIS data from some Federal States of Germany, 18 different crops or crop groups were mapped per pixel with 10 m resolution for Germany on an annual basis since 2018. These data sets enable a comparison of arable land use between years and the derivation of crop rotations on individual fields. More details and the underlying (in the meantime slightly updated) methodology can be found in Asam et al. 2022.
