SAP™ S/4HANA-Transformationsprojekte

Burkhard Pedell, Lukas Schilling, Sven Fahn, Stephan Lange et autres

Die Rahmenbedingungen für SAP ˆ S/4HANA-Transformationsprojekte und die Erfahrungsbasis haben sich in den letzten Jahren deutlich verändert. Der Beitrag untersucht auf Basis einer Erhebung bei Transformationsverantwortlichen im Jahr 2024, wie sich die Ziele, Methoden und Risiken von Transformationsprojekten im Vergleich mit einer …

Near real-time observations of snow water equivalent for SIOS on Svalbard – (SWESOS)

Julia Martin, Katharina Jentzsch, Niko Bornemann, William Cable et autres

Snow is an important component of the Svalbard permafrost and hydrological system due to its water storage and insulation properties. Continuous observations of snow properties in high-latitude such as Svalbard are almost non-existent, making it difficult to calibrate the current generation of …

Soil data at station Bayelva (2019, level 1)

Julia Boike, Inge Grünberg, Stephan Lange, Niko Bornemann et autres

Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the Bayelva Site at Ny-Ålesund, Svalbard, where meteorology, energy balance components and subsurface observations have been made for the last 20 years. The …

Near real-time observations of snow water equivalent for SIOS on Svalbard – (SWESOS)

Niko Bornemann, Stephan Lange, Sebastian Westermann, Julia Boike

In this report we summarize the outcome of our research project "Near real-time observations of snow water equivalent for SIOS on Svalbard – (SWESOS)", which was funded by Svalbard Integrated Arctic Earth Observing System (SIOS). We evaluate a new automated monitoring technique …

Automated in situ measurements of snow water equivalent, snow depth, snow temperature and snow dielectric constant, at the high Arctic Bayelva site during the winter period 2019/2020

Katharina Jentzsch, Sebastian Westermann, Jean‐Charles Gallet, Niko Bornemann et autres

The high Arctic Bayleva site is located on western Spitsbergen about 3 km from the settlement of Ny Ålesund. The provided data set comprises snow water equivalent (SWE) and snow depth measurements recorded by automated sensors installed in August 2019 close to …

Airborne LiDAR and stereo-photogrammetric characterization of permafrost landscapes and thaw subsidence

Ingmar Nitze, Guido Grosse, Julia Boike, Moritz Langer et autres

Rapid climate change in the northern high latitudes has a strong impact on permafrost stability, apparent as coastal erosion, subsidence, or lake dynamics with potentially severe consequences for local communities and ecology. In a rapidly warming Arctic, the monitoring of these processes …

Soil temperature and thaw depth differences associated with tundra vegetation types at Trail Valley Creek, NWT, Canada

Inge Grünberg, Bill Cable, Sofia Antonova, Stephan Lange et autres

Climate, vegetation, and permafrost are coupled through various positive and negative feedback loops in the Arctic and Subarctic. Many of these feedback mechanisms are still poorly quantified, in particular with respect to vegetation density or biomass. For instance, climate warming facilitates shrub …

A 16-year record (2002–2017) of permafrost, active-layer, and meteorological conditions at the Samoylov Island Arctic permafrost research site, Lena River delta, northern Siberia: an opportunity to validate remote-sensing data and land surface, snow, and permafrost models

Julia Boike, Jan Nitzbon, Katharina Anders, Mikhail N. Grigoriev et autres

Most of the world's permafrost is located in the Arctic, where its frozen organic carbon content makes it a potentially important influence on the global climate system. The Arctic climate appears to be changing more rapidly than the lower latitudes, but observational …
