Modellierungsdaten durchschnittlicher sommerlicher Hitzestress für Freiburg i. Br.

Modellierungsdaten zur mittleren Anzahl an Stunden mit Hitzestress pro Jahr (Mittelwert der Jahre 2019-2022). Hitzestress wird hierbei mit dem Universal Thermal Climate Index (UTCI) dargestellt und 26°C UTCI als Grenzwert genutzt. Der UTCI kombiniert Daten der Lufttemperatur, -feuchte, Windgeschwindigkeit und Strahlung zu einem Werte der "gefühlten" Temperatur. Alle Variablen des UTCI wurden mit Hilfe von KI auf unterschiedlichen räumlichen Auflösungen berechnet und gegen ein Messnetz validiert. Mehr Informationen zu den Modellen und Daten unter https://doi.org/10.5194/gmd-17-1667-2024. Die Berechnung der Daten erfolgte 2024 - eine Aktualisierung ist nicht geplant. Die Daten sind OpenData - Namensnennung: "Professur für Meteorologie, Universität Freiburg".

CC_GAR_Prec_2000_2050

BfG MapService 'CC_GAR_Prec_2000_2050', OGC:WMS 1.3.0; The maps and data sets summarise climate change information resulting from a well defined ensemble of 14 regional climate simulations (mainly based on EU-ENSEMBLES) for periods 2021 to 2050 and 2071 to 2100. The information are expressed as change of air temperature and precipitation with respect to the simulated present (1971-2000) averaged over meteorological seasons and 50km grid boxes. Based on the ensemble, a high, central and low estimate of the possible future development is given.

RS92 GRUAN Data Product (beta)

This product is based on Vaisala RS92 radiosonde measurements of temperature, humidity, wind and pressure that have been processed following the requirements of the GCOS Reference Upper Air Network (GRUAN) that were described in Immler et al. [2010]. The GRUAN data product file comply to the requirements of GRUAN in particular by providing a full uncertainty analysis. The uncertainty is calculated according to the recommendations of the “Guide for expressing uncertainty in measurement” [GUM2008]. The total uncertainty is assessed from estimates of the calibration uncertainty, the uncertainty of corrections and statistical standard deviations. Corrections are applied such that the data is bias free according to current knowledge.

Steigerung der Resilienz des Hopfenbaus gegenüber den Folgen des Klimawandels: Untersuchung der Chancen und Risiken von Agri-PV im konventionellen Hopfenbau, Teilprojekt B

Baukoerperstruktur und Stadtklima

Ziel der Untersuchung ist es, auf einer qualitativen und quantitativen Abschaetzung des Strahlungsenergie- und Waermehaushaltes charakteristischer Baukoerperstrukturen Regeln ueber die Gestaltung der thermischen und hygrischen Stadtklimaeigenschaften abzuleiten. Als Baukoerperstruktur wird das Mosaik aus Gebaeuden, Strassen, Rasenflaechen, Baumgruppen und evtl. Wasserflaechen verstanden. Alle Staedte weisen dem jeweiligen Baustil und der stadtplanerischen Auffassung ihrer Zeit entsprechende Strukturtypen auf. In ihnen wird zunaechst durch systematische Messfahrten die Lufttemperatur bei austauscharmen Wetterlagen gemessen. Anschliessend werden an ausgesuchten Modellfaellen die Oberflaechentemperaturen aller Strukturbestandteile im Tages- und Jahresgang festgestellt. Im dritten Schritt sollen die charakteristischen Tages- und Jahresgaenge der Strahlungstherme festgestellt werden.

CIRCVAL - Thermally forced circulations in an Alpine valley

Lower air volume in valleys than in adjacent plains together with diabatic heating or cooling induces an along-valley temperature and pressure gradient which drives the valley wind. This phenomenon will be quantified for the Mesolcina valley in the Swiss Alps. The method we develop is based on high resolution topography data. From this information the temperature and pressure tendency can be derived for a period with sensible heat flux at the surface. To calculate the wind field, the circulation theorem will be applied. The results of the model runs will be compared to measured data from the field experiment VOTALP (Vertical Ozone Transport in the Alps). In this campaign ground based and airborne instruments collected data of the atmospheric conditions in the valley and the synoptic windfield above.

Spatially modelling forest trafficability with ForHym and LiDAR-based cartographic depth-to-water

The thesis proposal deals with mapping weather-affected changes in soil moisture over time. This is to visualize where and when soils would be subject to severe rutting and compaction under forest operations. The approach taken is modular by connecting temporal hydrothermal processes dealing with soil wetting, drying, freezing, and thawing to spatially anticipated locations of dry versus wet soil drainage conditions. The temporal variations within specific textured soils can be modeled at daily resolution based on air temperature, and precipitation (rain, snow) data. This is done with the Forest Hydrology Model (ForHyM). The spatial variations can be derived from LiDAR-generated bare-ground elevation surfaces at 1 m resolution by way of the newly developed metric depth-to-water index (DTW), for which DTW less than 10 , 10-25, 25-50, 50-100, greater than 100 cm indicates very poor, poor, imperfect, moderately well and well drainage conditions, respectively. The results of doing so will be illustrated for forested areas in Northern and Central New Brunswick in reference to actual forest harvesting and wood forwarding tracks. The attempt is to generalize the methodology for weather-dependent and geospatially base forecasting of soil conditions to better enable forest operation planning as seasons change from dry to wet and from wet to dry within seasons and from year to year.

Estimates of land surface air temperature changes homogenised using sparse input 20th Century reanalysis product 20CRv3

The data consist of 4 frozen gridded estimates as described in Gillespie et al, 2022. The data are presented as 5 degree resolution global fields over 1850-2014. Station data arising from the International Surface Temperature Initiative (ISTI) global databank of monthly holdings have been homogenised using 20CRv3 to identify breakpoints. Four distinct approaches to adjustment have been undertaken resulting in 4 separate estimates of the resulting series. The gridding is a simple gridbox average of any observations available within each 5 degree gridbox. Data is available for those global land areas for which underlying station data are available in teh ISTI holdings.

Eurasian Modern Pollen Database (former European Modern Pollen Database)

The Eurasian Modern Pollen Database (EMPD) contains modern pollen data (raw counts) for the entire Eurasian continent. Derived from the European Modern Pollen Database, the dataset contains many more samples West of the Ural Mountains. We propose this dataset in three different format: 1/ an Excel spreadsheet, 2/ a PostgreSQL dump and 3/ a SQLite3 portable database format. All three datasets are strictly equivalent. For download see "Original Version".
