Maffei, C. (author)Forest fires are a major ecosystem disturbance at global scale, put pressure on agencies in charge of citizens and infrastructure security and cause unvaluable human losses. Fires are controlled by multiple static and dynamic drivers related to topography, land cover, climate, weather, and anthropic activity. Among these, weather is an active...doctoral thesis 2022

Mueller, Marlin M. (author), Dubois, Clémence (author), Jagdhuber, Thomas (author), Hellwig, Florian M. (author), Pathe, Carsten (author), Schmullius, Christiane (author), Steele-Dunne, S.C. (author)Forests’ ecosystems are an essential part of the global carbon cycle with vast carbon storage potential. These systems are currently under external pressures showing increasing change due to climate change. A better understanding of the biophysical properties of forests is, therefore, of paramount importance for research and monitoring...journal article 2022

Liu, Lian (author), Menenti, M. (author), Ma, Yaoming (author), Ma, Weiqiang (author)Snowfall and the subsequent evolution of the snowpack have a large effect on the surface energy balance and water cycle of the Tibetan Plateau (TP). The effects of snow cover can be represented by the WRF coupled with a land surface scheme. The widely used Noah scheme is computationally efficient, but its poor representation of albedo needs...journal article 2022

Hu, Zhongyang (author), Kuipers Munneke, Peter (author), Lhermitte, S.L.M. (author), Dirscherl, Mariel (author), Ji, Chaonan (author), van den Broeke, Michiel (author)Antarctic blue ice areas are exposed due to erosion and sublimation of snow. At the same time, surface melt can form surface types that are spectrally similar to blue ice, especially at low elevations. These are termed melt-induced blue ice areas. Both types of blue ice are sensitive indicators of climate change. Satellite remote sensing is a...journal article 2022

The Indus River basin is considered as one of the world’s large river basins, comprising several major tributaries, and has experienced severe floods in its history. There is currently...journal article 2022

Verhoeven, Vincent B. (author), Dedoussi, I.C. (author)Land cover plays an important role in the Earth's climate as it affects multiple biochemical cycles and is critical for food security and biodiversity. As land cover is continuously evolving, influenced by anthropogenic and other factors, the availability of temporally varying land cover data sets of large spatial domains is integral to...journal article 2022

Zhang, Jing (author), Jia, Li (author), Menenti, M. (author), Zhou, Jie (author), Ren, Shaoting (author)Glacier and snow are sensitive indicators of regional climate variability. In the early 21st century, glaciers in the West Kunlun and Pamir regions showed stable or even slightly positive mass budgets, and this is anomalous in a worldwide context of glacier recession. We studied the evolution of snow cover to understand whether it could...journal article 2021

Maffei, C. (author), Lindenbergh, R.C. (author), Menenti, M. (author)Forest fires preparedness strategies require the assessment of spatial and temporal variability of fire danger. While several tools have been developed to predict fire occurrence and behaviour from weather data, it is acknowledged that fire danger models may benefit from direct assessment of live fuel condition, as allowed by Earth Observation...journal article 2021

Eutrophication prediction in the Dutch coastal waters using remote sensing data and machine learningChatzopoulos Vouzoglanis, Konstantinos (author)Eutrophication processes in coastal waters are becoming more prominent as a result of high nutrient discharges from intensive agriculture and increased urban waste. These processes can be devastating for local ecosystems and lead to dissolved oxygen depletion, which applies considerable stress on aquatic organisms. For ecosystems to preserve...master thesis 2019

Maffei, C. (author), Menenti, M. (author)Operational forest fire danger rating systems rely on the recent evolution of meteorological variables to estimate dead fuel condition. Further combining the latter with meteorological and environmental variables, they predict fire occurrence and spread. In this study we retrieved live fuel condition from MODIS multispectral measurements in...journal article 2019

Maffei, C. (author), Alfieri, S.M. (author), Menenti, M. (author)Forest fires are a major source of ecosystem disturbance. Vegetation reacts to meteorological factors contributing to fire danger by reducing stomatal conductance, thus leading to an increase of canopy temperature. The latter can be detected by remote sensing measurements in the thermal infrared as a deviation of observed land surface...journal article 2018

Ratering Arntz, Lexy (author)More than half of Vietnam's national rice production is produced in the Mekong Delta. Many hectares of rice were damaged due to extensive salinity intrusion during the dry season of 2016. The impact of salinity intrusion on rice production is studied by (1) mapping the impact using remote sensing data (MODIS NDVI time-series) and (2)...master thesis 2018

Kiptala, J.K. (author)For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent.
