Introduction
Currently I am working on an eddy covariance data set analyzing the exchange of heat, momentum, H2O, CO2 and CH4 between eutrophic lake Dagow (NW Germany) and the atmosphere. The aim is to find out, how lake (water temperature, dissolved oxigen, stratification) and atmospheric parameters (wind, barometric pressure, insolation etc.) affect carbon and heat exchange on different time scales, ranging from diurnal cycles to multi-year variability.

Article
Full-text available
Over the past decades, human‐induced climate change has led to a widespread wetting and warming of the Tibetan Plateau (TP), affecting both ecosystems and the carbon cycling therein. Whether the previously observed climate changes stimulate carbon uptake via enhanced photosynthesis or carbon loss via enhanced soil respiration remains unclear. Here...

Full-text available
The Tibetan alpine steppe ecosystem covers an area of roughly 800 000 km2 and contains up to 3.3 % soil organic carbon in the uppermost 30 cm, summing up to 1.93 Pg C for the Tibet Autonomous Region only (472 037 km2). With temperatures rising 2 to 3 times faster than the global average, these carbon stocks are at risk of loss due to enhanced soil...

The Tibetan Plateau (TP) is the largest alpine plateau on Earth and plays an important role in global climate dynamics. On the TP, climate change is happening particularly fast, with an increase in air temperature twice the global average. The particular sensitivity of this high mountain environment allows observation and tracking of abiotic and bi...

Between December 2015 and March 2016, fog water was collected at the subtropical mountain cloud forest site Ailaoshan in SW China at 2476 m above mean sea level. An active fog collector was employed to collect 117 samples during more than 140 hours of fog, covering 6 major fog events. The chemical analysis included acidity and inorganic ion concent...

South Patagonian peat bogs are little studied sources of methane (CH4). Since CH4 fluxes can vary greatly on a small scale of meters, high-quality maps are needed to accurately quantify CH4 fluxes from bogs. We used high-resolution color infrared (CIR) images captured by an Unmanned Aerial System (UAS) to investigate potential uncertainties in tota...

Bidirectional fog droplet fluxes were observed at two mountainous subtropical forests in East Asia. To investigate the various boundary conditions and that cause these bidirectional droplet fluxes, we set up identical eddy covariance systems including a droplet spectrometer (FM100 Fog monitor) at two study sites in the Ailaoshan (SW China) and Xito...

The detection of pest infestation is an important aspect of forest management. In the case of the oak splendour beetle (Agrilus biguttatus) infestation, the affected oaks (Quercus sp.) show high levels of defoliation and altered canopy reflection signature. These critical features can be identified in high-resolution colour infrared (CIR) images of...

Project
The research program is based on joint Sino-German fieldwork in the catchment of Nam Co, southern Tibetan Plateau. The overarching goal of TransTiP is thus to quantify rates and magnitudes of change in Earth surface fluxes with high temporal and spatial resolution to understand underlying processes in three interlinked main research areas: (1) sediment fluxes (S), (2) carbon fluxes (C), and (3) water fluxes and water quality (W), and how these processes will affect water resources, biodiversity as well as species composition and distribution in the future. I specialize on: Invertebrates and their isotope composition as paleohydrological proxies.
Project
The DFG-funded Sino-German doctoral Research Training Group TransTiP, works on the research fields of Sediment/Water/Carbon fluxes at NamCo lake (TP, Tibetan Plateau). The interaction and the transition of these fluxes regarding to climate change can be observed especially in high mountain environments. The research program aims to (1) understand controlling mechanisms and processes by quantifying rates and magnitudes of sediment movement and transport with high temporal and spatial resolution, to (2) identify the impact of land-use change on organic carbon storage in soil and associated carbon fluxes to atmosphere and hydrosphere, to (3) determine how these processes have affected water balances and geo-ecosystems, and to (4) establish an intensive sino-german doctoral collaboration to combine different research fields and to use synergies of different backgrounds and cultures. Subproject Permafrost, periglacial landforms and processes: Periglacial landforms and processes at NamCo lake underlying a special regional climate setting. The drivers of these setting are an intersection of the Westerlies, the South West Asian monsoon, and the East Asian monsoon. Additionally, sediment fluxes in high mountain areas are controlled by strong temperature variations and a seasonal variability. The elevation of a smaller subcatchment (Qugaqie basin, 60km²) ranges from 4718 (lake level NamCo) up to 6188 m a.s.l., which supposes a strong influence of permafrost and the periglacial process domain troughout the year. However, the most precipitation (90% of MAP, around 280 mm) occurs in summertime while the South West Asian summer monsoon. The aim of the study is to assess the lower boundary of permafrost occurrence defining the areas of ongoing periglacial processes and existing landforms.
