Mapping and Understanding Patterns of Air Quality Using Satellite Data and Machine Learning
; ; ; (Journal of Geophysical Research: Atmospheres, 2020)
The quantification of factors leading to harmfully high levels of particulate matter (PM) remains challenging. This study presents a novel approach using a statistical model that is trained to predict hourly concentrations ... -
Mapping leaf area index over semi-desert and steppe biomes in kazakhstan using satellite imagery and ground measurements
(EARSeL eProceedings, 2009)Maps of peak seasonal leaf area index (LAI) were produced using the Normalised Difference Vegetation Index (NDVI) from SPOT VEGETATION (VEG) satellite at 1 km resolution over a large region in the semi-arid zone of Kazakhstan. ... -
Mapping the 3D position of battery cathode particles in Bragg coherent diffractive imaging
(Journal of Synchrotron Radiation, 2023-02-16)In Bragg coherent diffractive imaging, the precise location of the measured crystals in the interior of the sample is usually missing. Obtaining this information would help the study of the spatially dependent behavior of ... -
Mapping the Brightness of Ganymede's Ultraviolet Aurora Using Hubble Space Telescope Observations
;; ; ; ; ; (Journal of Geophysical Research: Planets, 2022-06-15)
We analyze Hubble Space Telescope observations of Ganymede made with the Space Telescope Imaging Spectrograph between 1998 and 2017 to generate a brightness map of Ganymede's oxygen emission at 1,356 Å. Our Mercator projected ... -
Mapping the Thermal Structure of Southern Africa From Curie Depth Estimates Based on Wavelet Analysis of Magnetic Data With Uncertainties
; ; ; (Geochemistry, Geophysics, Geosystems, 2021-11-16)
Surface heat flow provides essential information on the thermal state and thickness of the lithosphere. Southern Africa is a mosaic of the best‐preserved and exposed crustal blocks, assembled in the early late Archean and ... -
Marble bowing: comparative studies of three different public building facades
(Environmental geologyEnvironmental geology, 2008)The veneer cladding of the Oeconomicum (OEC, Göttingen), the State Theatre of Darmstadt (STD, Darmstadt) and of the State and University Library (SUB, Göttingen) is characterised by pronounced bowing after a short time of ... -
Marble decay: towards a measure of marble degradation based on ultrasonic wave velocities and thermal expansion data
(Environmental Earth Sciences, 2021-05-23)Marble as ornamental and dimensional stones as well as in their natural environments show complex weathering phenomena. Physical, chemical, and biological weathering of marble are well documented. The impact of climate ... -
Marine Fauna im Pleistozän-Pliozän von Skagaheidi, Nord-Island: Vorläufige Mitteilung

Marine gravimetric and magnetic investigations within the area of the southeastern Mediterranean Sea and the northern section of Egypt
(Univ. Hamburg, 2004)The southeastern Mediterranean Sea and the northern section of Egypt constitutes one of the most complex tectonic areas in the Mediterranean. This study is an attempt to achieve a better understanding of tectonics, and ... -
Marine Interglacial Deposits in the Cuxhaven Area, NW Germany: A Comparison of Holsteinian, Eemian and Holocene Foraminiferal Faunas
(E&G – Quaternary Science Journal; Vol.38, No. 1)Es werden interglaziale Foraminiferen-Faunen aus dem Holstein, dem Eem und dem Holozän für den Raum Cuxhaven beschrieben. Bei den bearbeiteten Proben handelt es sich um Material aus Kernbohrungen. Die Vergesellschaftungen ... -
Marine Signale im höheren Buntsandstein der Trier-Luxemburger Bucht? - Teil IV: Sequenzstratigraphische Gesamtausdeutung
(Mainzer geowissenschaftliche Mitteilungen; 48. 2020)Im linksrheinischen Mittleren und Oberen Buntsandstein werden Hoch- und Tiefstände des Baselevels rekonstruiert. Die jeweiligen Steuerungsfaktoren waren Meeresspiegel- Schwankungen und – vor allem – Tektonik, bei recht ... -

This study verified the inter‐related effect of ‘market distance’, defined as walking time, ‘farm typology’, defined as resource endowment, and ‘site’, defined as geographic location with contrasting agro‐ecologies, as ... -
Martian Atmospheric Spectral End‐Members Retrieval From ExoMars Thermal Infrared (TIRVIM) Data
; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Planets, 2022-09-09)
Key knowledge about planetary composition can be recovered from the study of thermal infrared spectral range datasets. This range has a huge diagnostic potential because it contains diagnostic absorptions from a planetary ... -
Mass distribution at the galactic centre
(Univ. Köln, 2005)In the framework of this PhD thesis, the study of the distribution of an extended mass close to the super-massive black hole (SMBH) at the centre of our Galaxy is addressed using observational data and theoretical modelling. ... -
Mass Occurrences of the Brachiopod Halorella in Late Triassic Methane-Seep Deposits, Eastern Oregon
