Spatial distribution of aerosol and meteorological parameters measured during flight SourceFFR_ALADINA_20241016_10 with the UAS ALADINA near Frankfurt airport in October 2024

Exposure to ultrafine aerosol particles (UFPs) can cause adverse effects on human health, local environment and climate. Air traffic is associated with the emission of high numbers of UFPs, which results in increased UFP number concentrations close to airports. So far, the spatial distribution and variability of UFPs is poorly understood in the atmospheric boundary layer. The uncrewed aerial system (UAS) ALADINA (Application of Lightweight Aircraft for Detecting In-situ Aerosols, e.g. Altstädter et al., 2015) was operated close to the largest airport in Germany at Frankfurt airport (FRA) between 11 and 19 October 2024. The dataset provides airborne in-situ observations of the spatial distribution of aerosol particle number concentration with different sizes and meteorological parameters of temperature, humidity, wind, surface temperature and short-wave irradiance, as well as accurate position and orientation of ALADINA. Data are available from 26 measurement flights, comprising a number of 122 vertical profiles between ground and a maximum altitude of 750 m above mean sea level (ASL) and about 70 horizontal legs at different but constant altitude, e.g. in 100 m altitude intervals. Details about the ALADINA measurements will be provided in a publication (Harm-Altstädter et al., in prep.) soon.

Fernerkundung - Luftbilder Hamburg

In der <b> Fernerkundung - Luftbilder</b> werden detaillierte Luftbilder der Freien und Hansestadt Hamburg als hochwertige Geodaten bereitgestellt. Luftbilder als Geodaten? Bei Luftbildern handelt es sich nicht um herkömmliche Fotografien, sondern um qualitative Abbildungen der Erdoberfläche, die lagegenau verortet sind. Ein unverzichtbares Werkzeug der Erdbeobachtung. Wie werden die Bilder aufgenommen? Zum Einsatz kommen unterschiedliche Aufnahmesysteme (<b>Pkw, Drohne, Flugzeug, Satellit</b>) mit unterschiedlicher Sensorik (RGB-, Multispektral-Sensorik). Jede Kombination bringt verschiedene Vor- und Nachteile mit sich, was sich in der räumlichen Auflösung (GSD), zeitlichen Auflösung (Aktualität), spektralen Auflösung (Anzahl der Kanäle) und den Nutzungsbedingungen widerspiegelt. Sind die Unterschiede nachteilig? Keinesfalls! Die Vielfalt ermöglicht es erst, eine Vielzahl an Anwendungsbereichen abzudecken. Somit gibt es für jeden Anwendungsfall einen geeigneten Datensatz. Die Aufnahmen unterstützen in der Stadt- und Verkehrsplanung, der Umweltbeobachtung und sind als Trainingsdaten für KI-Anwendungen geeignet. Von simpler #Betrachtung, über #Erkennung, #Change Detection, hin zu flächendeckendem #Monitoring und #Analysen. Unser Ziel ist es, diese hochwertigen Daten nicht nur Fachleuten, sondern auch der Öffentlichkeit zugänglich zu machen – leicht verständlich und nutzerfreundlich (#Geoportal Hamburg). <b>&#8594; Ein Blick in die Daten lohnt sich.</b>

Urban Heat Islands (UHI) Krefeld

Mit Hilfe dieser Daten können besonders stark aufgeheizte Stadtteile genauso wie kühlere, klimatisch ausgeglichenere Zonen identifiziert werden. Der Urban Heat Island (UHI)-Effekt beschreibt das Phänomen, dass sich der städtische Raum gegenüber den umliegenden ländlichen Regionen vermehrt aufheizt. Dieser Effekt ist vor allem im Sommer und in der Nacht deutlicher ausgeprägt und kann negative Auswirkungen auf die Gesundheit und das Wohlbefinden der städtischen Bevölkerung haben. Die vermehrte Wärmeansammlung im städtischen Gebiet ist von verschiedenen Faktoren abhängig. Dabei spielt u.a. der Anteil an Bebauung, Bodenversiegelung, der Begrünungsgrad, die verwendeten Baumaterialien und anthropogene Wärmeerzeugung eine wichtige Rolle. Aufgrund der deutlicheren Ausprägung dieses Überwärmungseffekts in der Nacht sind die UHI-Daten in zwei Kategorien unterteilt: UHI-Index am Tag und UHI-Index in der Nacht. Der UHI-Index wird in Kelvin angegeben und beschreibt den Unterschied zwischen städtischen und ländlichen Temperaturen. Die Daten sind für die Jahre 2023, 2024 und 2025 verfügbar.

Digital Orthophotos and water-land-boundaries at the Elbe estuary (Germany), July 2022, Sat-Land-Fluss-project

In July 2022 we mapped the tidal area of the Elbe near Cuxhaven and Brunsbüttel. The data was gathered by UAV (Unmanned Aerial Vehicle) with a RBG camera and a PDGNSS-Rover (Precice Differential Global Navigation Satellite System) in three areas: 1) Otterndorf at low tidal level (beach area), 2) Neufelderkoog at low tidal level (wadden area), 3) Neufeld at high tidal level (flooded reed area). For each area we provide a digital orthophoto and the correlation of the measurement timing to the local sea level. The measurements were obtained at the same time as the radar satellite Sentinel 1 crossed the area. The data is structured in three zip-archives corresponding to the study areas: 1) 20220712_Tnw_Otterndorf.zip: provides the time series data as comma-separated text files (CSV)  provides (a) a digital orthophoto at 1,5 cm resolution, (b) an overview jpg showing of the measurement times and the local sea level, (c) timing of the UAV-flightlines and (d) two PDGNSS measurement series collected simultaneously as csv. (downloadable as 10.4 GB zip archive),  2) 20220712_Tnw_NeufelderkoogPriel.zip: provides (a) a digital orthophoto at 2 cm resolution and (b) an overview jpg showing of the measurement times and the local sea level (downloadable as 6,3 GB zip archive),  3) 20220720_Thw_Neufeld.zip: provides (a) a digital orthophoto at 2 cm resolution and (b) an overview jpg showing of the measurement times and the local sea level (downloadable as 8,4 GB zip archive). The data is used in the frame of the project "satellite based water-land-boundary detection" (Sat-Land-Fluss), as validation for Sentinel-1 derived water-land determinations. Sat-Land-Fluss was a R&D project lasting from 2020-2024, funded by the German Federal Ministry for Digital and Transport in the 4th project call "National Copernicus Application" (50EW2015).
