Machbarkeitsstudie Deutschlandweite Befragung von Unternehmen zur Klimawandelanpassung

Die Folgen des Klimawandels bergen ökonomische Risiken für Unternehmen. Die physische Klimarisiken - insb. Extremwetterereignisse, veränderte Niederschlagsmuster und erhöhte Durchschnittstemperaturen - können zu Produktionsrückgängen, steigenden Rohstoffkosten und Gebäudeschäden führen. Nach einer aktuellen Studie des Umweltbundesamts berichten nur etwa die Hälfte der DAX-30-Unternehmen zu diesen Risiken. Dabei schätzt allein diese Gruppe die potenziellen Schäden auf einen Gesamtwert von mehreren Milliarden Euro. Über das Risikobewusstsein in anderen Unternehmen, insbesondere KMU, ist wenig bekannt. Ziel dieses Vorhabens ist es, eine Machbarkeitsstudie für die Befragung von Unternehmen bezüglich Klimarisiken und des Umgangs mit Klimawandelanpassung zu erstellen. Dabei sollen die Möglichkeiten eine repräsentative Erhebung, etwa im Rahmen existierender Unternehmenspanels, eruiert, mögliche Fragenkomplexe entworfen sowie ein handbares Konzept erstellt werden. Auch sollen vergleichbare Erhebungen in anderen OECD-Ländern als Benchmark recherchiert werden. In einer Themenkonferenz im 3. Projektjahr sollen Zwischenergebnisse mit der Zielgruppe diskutiert werden.

CAMELS-DE-1h: hourly hydro-meteorological time series, weather forecasts, and attributes for 1611 catchments in Germany

CAMELS-DE-1h provides a comprehensive and harmonized collection of hydro-meteorological data for 1611 catchments across Germany. The time series data cover the period from 2001 to 2024 and provide measurements of discharge, water level, and meteorological variables in hourly resolution for all catchments. The metorological variables are aggregated to the catchment areas from the gridded data sources RADKLIM-YW and HOSTRADA (DWD) and encompass the variables precipitation, air temperature, humidity, water vapor mixing ratio, global radiation, air pressure, cloud cover, dew point temperature, wind speed, and wind direction. In addition, deterministic and ensemble weather forecasts with a 48-hour lead time, readily processed for all catchments from the ICON-D2 model (DWD), are included for the period 2021 to 2024. The dataset also provides static catchment attributes encompassing topography, soils, land cover, hydrogeology, and human influences. Furthermore, to serve as a baseline for further model development, the dataset includes discharge simulation results from a regionally trained LSTM and a catchment-calibrated HBV (Hydrologiska Byråns Vattenbalansavdelning) conceptual model. A comprehensive description of the dataset can be found in the accompanying data description paper. Key features of CAMELS-DE-1h: 1. Hydro-meteorological time series data in hourly resolution (2001–2024) 2. Historical deterministic and ensemble weather forecasts from ICON-D2 with a 48-hour lead time (2021–2024) 3. Catchment attributes 4. Benchmark discharge simulation results from an LSTM and the HBV model

Multibeam bathymetry processed data (Reson SeaBat T50-P working area dataset) of RV Littorina during cruise L13-20 including navigation files and python scripts for automated terrain based navigation correction

Multibeam bathymetry raw and processed data (RESON Seabat T50Extended Range) of Research Vessel Littorina at Fehmarn Belt in the western part of the Baltic Sea. The raw data (.db format) were processed using QPS Qimera software (v 1.7), based on the following workflow: 0.Raw data -> 1.Apply correct Sound Velocity Profiles -> 2. correct lever arm offsets -> 3. Finalize with manual 2D and 3D point editing. The corrected soundings were used to create a GeoTIFF (EPSG Code:4326) .gsf data and GeoTIFF are provided. In addition software is provided with the aim of establishing a benchmark for terrain based navigation correction software using mutlibeam data. A) A script that allows to alter navigation solutions B) A script that allows to compare navigation solutions By altering the original and correct navigation and using the product as a basis for a terrain based navigation correction algorithm, the quality of such an algorithm can be measured by comparing its output to the original navigation. This in turn allows quantitative comparisons between different algorithms or settings. In addition to the original navigation some altered navigation files are provided (in .csv file format).

Kombinierte Mobilität durch Mobilitätsmanagement am Beispiel eines Naherholungsraumes sowie einer touristischen ländlichen Region

Auf der Grundlage einer Bestandsaufnahme von best-practice-Beispielen, einem Vergleich der Situation im Rahmen eines benchmarkings sowie einer Stärken-Schwächen-Analyse von Angebot, Marketing und angebotsbildenden Prozessen werden konzeptionelle Vorschläge für ein Mobilitätsmanagement erarbeitet. Bei der Analyse ebenso wie bei der Entwicklung von Maßnahmen werden alle betroffenen Akteure in einer Dialogplattform eingebunden und damit eine dauerhafte Entwicklung angestoßen. Aus dem Dialogprozess werden Empfehlungen herausgearbeitet und in einem Handlungsleitfaden zusammengefasst.

Climate and environmental impact of nuclear power

The report assesses nuclear energy’s role in the transformation to net-zero greenhouse gas emissions by 2050. It contrasts top-down net-zero pathways from five integrated assessment models with a comprehensive bottom-up review of national programmes, including newcomer countries, and benchmarks these against the COP28/29 pledge to triple nuclear capacity. It further analyses system requirements in renewables-dominated grids, climate-change risks to plant reliability, and a harmonised cradle-to-grave environmental footprint of nuclear power across 40 regional life-cycle chains (2020 and 2030). Severe-accident impacts and proliferation risks are discussed, and life-cycle costs and GHG abatement costs of new nuclear (incl. SMRs) are compared with wind and solar.

HeideBench: A Multispectral UAV Time-Series Benchmark for Forest Crown Phenology in Dölauer Heide

We present HeideBench, a very-high-resolution multispectral uncrewed aerial vehicle dataset for forest crown phenology collected over a forest patch in Dölauer Heide, Halle (Saale), Germany. Dölauer Heide is currently dominated by pine plantations (Kiefernforste), which cover the largest area but are increasingly affected by dieback, while its potential natural vegetation is sessile oak–hornbeam forest rich in small-leaved lime (Albrecht et al., 1993). In addition to these pine stands, the area contains near-natural mixed deciduous forests with oaks, birches, and beeches, making it a particularly relevant setting for observing seasonal canopy development under contrasting forest structures and ongoing ecological transition. Against this background, HeideBench provides repeated observations of the same forest patch through the growing season. The dataset contains 18 georeferenced multispectral GeoTIFF orthomosaics acquired between 6 March 2025 and 5 November 2025, spanning a 244-day seasonal period from early spring to late autumn. The acquisitions have a median revisit interval of 14 days, with intervals ranging from 4 to 27 days, and an average ground sampling distance of 5.53 cm per pixel. The valid imaging footprint covers approximately 32.1 ha and is bounded by 11.902653–11.911325°E and 51.499959–51.508576°N. Data were collected using a DJI Mavic 3M Enterprise uncrewed aerial vehicle equipped with four multispectral cameras measuring green (560 nm), red (650 nm), red-edge (730 nm), and near-infrared (860 nm) reflectance, in that order. Flights used a real-time kinematic (RTK) positioning module for centimeter-level geolocation, and all data are provided in coordinate reference system EPSG:25832. Imagery was processed with Agisoft Metashape 2.3.1 to generate calibrated multispectral orthomosaics. The dataset further includes 5,885 crop-safe individual tree crown instance segmentations over the same footprint, extracted with the DeepTrees software package (Khan et al., 2025). HeideBench is intended to support crown-centric analyses of seasonal canopy development, temporal representation learning, phenology-aware feature extraction, and the evaluation of tree crown delineation under seasonal change. HeideBench is a result of the Dynamic Platform Project titled "PhenoEmbed: Multispectral UAV AI Embeddings for phenology-aware tree crown delineation" of the Integration Platform 1: "Sustainable future land use" (IP1) at the Helmholz Centre for Environmental Research (UFZ) in Leipzig, Germany.
