Trockenfallende Gewässer Hamburg

Der Dienst "Trockenfallende Gewässer Hamburg" enthält als WMS-Darstellungsdienst und WFS-Downloaddienst die in der Studie "Untersuchung der Niedrigwassersituation in Hamburg unter besonderer Berücksichtigung der Jahre 2018 bis 2020" ermittelten Gewässerabschnitte. Diese werden eingeteilt in drei Abflusskategorien in Trockenzeiten: Wenig Abfluss Manchmal trocken Trocken und basieren auf Literaturrecherche, Pegelauswertungen und Befragungen der Bezirke und Umweltverbände NABU und BUND durch die BWS GmbH. Um die Datengrundlage zu verbessern können Beobachtungen in einem Meldeportal eingetragen werden. Zu finden ist das Meldeportal unter https://trockener-bach.beteiligung.hamburg.

Soil temperature, volumetric water content, electrical conductivity, air temperature and atmospheric pressure measured every 10 minutes in a grass- and a herb-dominated area at a summer dike, Butjadingen, Germany (Nov 2022–Nov 2023)

To understand the role of plant species and functional diversity on the physical soil parameters of a sea dike, especially under prolonged drought conditions, continuous measurements of soil temperature, volumetric water content (soil moisture), soil electrical conductivity (EC), air temperature and atmospheric pressure were carried out from 22 November, 2022, to 22 November, 2023. The measurements were taken using six soil sensors from METER Group's TEROS 12 series, which were installed at three distinct soil depths (4 cm, 14 cm, 24 cm) and on two differently vegetated dike areas: one area with a grass-dominated plant community (referred to as 'Mix-Grass') and one area with a herb-dominated plant community (referred to as 'Mix-Herb'). The sensors were mounted on the southern (inland) side of a summer dike, which is located at the south-eastern North Sea coast of Germany (Butjadingen, Wesermarsch; 'Mix-Grass': 53.61211876 ° N, 8.330925695° E, 'Mix-Herb': 53. 61210826° N, 8.330989015° E), about 1 m below the dike crest. The dike height is approximately 3.6 m above mean high water (MHW). The measurement data was logged at 10-minute intervals using a ZL6 logger from the METER Group.

Soil moisture distribution at the Hordorf (Central Germany) groundtruthing site determined by mobile Cosmic Ray Neutron Sensing

Cosmic Ray neutron sensing (CRNS) is an emerging technology which is used to close the scaling gap between point measurements, such as TDR or soil samples, and the airborne remote sensing data. CRNS estimates the area-average soil water content by the detection of soil-reflected cosmic-ray neutrons in air. This method is characterized by an non-linearly shaped horizontal footprint of hundreds of meters and a vertical footprint of tens of centimetres (Köhli et al. 2015). During the campaign, a portable sensor (the so-called CRNS Rover) was used to study the spatial soil moisture variability in the target area in Hordorf. The rover was equipped with a CRNS-RV unit from Hydroinnova LLC (HI-RC01 detector) and a polyethylene shield below the detector to better reduce local effects of the field track. Neutron count data were processed including several physical, soil, and terrain corrections (see Schrön 2020, cfg file and the software <https://git.ufz.de/CRNS/cornish_pasdy>) to obtain the spatial soil moisture distribution at the Hordorf ground truthing site.

Evolving Regions Kreis Wesel - Klimawirkung Landwirtschaft | Dürre

Diese Klimawirkung beschreibt den Zusammenhang zwischen Dürre und landwirtschaftlichen Nutzungen. Dieser Datensatz ist Teil der Klimawirkungsanalyse im Projekt "Evolving Regions" für den Kreis Wesel. Bei Evolving Regions handelt es sich um eine in den Jahren 2021 -2023 gefördertes life-ClimAdapt-Projekt. Zentrale Basis des Projektes stellt die durch das Institut für Raumplanung der TU Dortmund (IRPUD) erstellte Klimawirkungsanalyse (KWA) dar, bei der die Wirkung verschiedener Klimasignale auf konkrete räumliche Gegebenheiten bzw. Sensitivitäten des Raums berechnet worden ist.

Tree-ring width measurements of Douglas fir from Kaiserslautern from 1917 to 2021

Wood samples from Douglas fir trees were taken using an increment borer. From each tree two opposing increment cores were taken at breast height. The sampled trees stood in an area of ~50x50 meters. Total ring width was measured and digitized. The resulting two radii measurements of each tree were visually synchronized and averaged to form a tree-ring series. Additionally, metadata were collected such as tree height, circumference and provenance (coastal, interior). The tree-ring data were used to investigate the resilience, resistance and recovery of the Douglas fir trees to severe drought events and to perform climate sensitivity analysis. This tree-ring dataset was part of a sampling campaign to assess the growth potential of Douglas fir trees until the year 2100. Annual tree growth variability until 2100 was modeled for Germany (including the river basins draining to Germany) with a spatial resolution of 12x12 km using regional climate projections ensemble.
