Climate effects on vegetation vitality at the treeline of boreal forests of Mongolia
Klinge, Michael; Dulamsuren, Choimaa; Erasmi, Stefan; Karger, Dirk Nikolaus; Hauck, Markus (Biogeosciences, 2018)In northern Mongolia, at the southern boundary of the Siberian boreal forest belt, the distribution of steppe and forest is generally linked to climate and topography, making this region highly sensitive to climate change ... -
Evaluating the Quality and Accuracy of TanDEM-X Digital Elevation Models at Archaeological Sites in the Cilician Plain, Turkey
Erasmi, Stefan; Rosenbauer, Ralph; Buchbach, Ralf; Busche, Thomas; Rutishauser, Susanne (Remote Sensing, 2014) -
Greenhouse gas emissions from soils—A review
Oertel, Cornelius; Matschullat, Jörg; Zurba, Kamal; Zimmermann, Frank; Erasmi, Stefan (Chemie der Erde - Geochemistry, 2016)Soils act as sources and sinks for greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Since both storage and emission capacities may be large, precise quantifications are needed ... -
Multi-Source Remotely Sensed Data Combination: Projection Transformation Gap-Fill Procedure
Boloorani, Ali Darvishi; Erasmi, Stefan; Kappas, Martin (Sensors, 2008)In this work a new gap-fill technique entitled projection transformation has been developed and used for filling missing parts of remotely sensed imagery. In general techniques for filling missing areas of an image break ... -
Russian boreal peatlands dominate the natural European methane budget
Schneider, Julia; Jungkunst, Hermann F.; Wolf, Ulrike; Schreiber, Peter; Gažovič, Michal; Miglovets, Mikhail; Mikhaylov, Oleg; Grunwald, Dennis; Erasmi, Stefan; Wilmking, Martin; Kutzbach, Lars (Environmental Research Letters, 2016)About 60% of the European wetlands are located in the European part of Russia. Nevertheless, data on methane emissions from wetlands of that area are absent. Here we present results of methane emission measurements for ... -
Understanding Forest Health with Remote Sensing - Part I - A Review of Spectral Traits, Processes and Remote-Sensing Characteristics
Lausch, Angela; Erasmi, Stefan; King, Douglas; Magdon, Paul; Heurich, Marco (Remote Sensing, 2016)Anthropogenic stress and disturbance of forest ecosystems (FES) has been increasing at all scales from local to global. In rapidly changing environments, in-situ terrestrial FES monitoring approaches have made tremendous ... -
Understanding Forest Health with Remote Sensing-Part II—A Review of Approaches and Data Models
Lausch, Angela; Erasmi, Stefan; King, Douglas; Magdon, Paul; Heurich, Marco (Remote Sensing, 2017)Stress in forest ecosystems (FES) occurs as a result of land-use intensification, disturbances, resource limitations or unsustainable management, causing changes in forest health (FH) at various scales from the local to ... -
Vegetation Greenness in Northeastern Brazil and Its Relation to ENSO Warm Events
Erasmi, Stefan; Schucknecht, Anne; Barbosa, Marx; Matschullat, Jorg (Remote Sensing, 2014)The spatio-temporal variability of trends in vegetation greenness in dryland areas is a well-documented phenomenon in remote sensing studies at global to regional scales. The underlying causes differ, however, and are often ...
