    Getachew Agmuas Adnew (Postdoc)

    Utrecht University

    Getachew Agmuas Adnew is a postdoctoral researcher at the institute for marine and atmospheric research, Utrecht (IMAU), Utrecht University. His reach focuses on the exchange of CO2 between the atmosphere and the biosphere and the oxidation capacity of the atmosphere. In his research, he uses stable isotopes of CO2 (𝛿13C, 𝛿18O, Δ17O, Δ47) to understand CO2 exchange between the atmosphere and the biosphere and stable isotopes of O2 (Δ35 and Δ36) to estimate the oxidation capacity of the atmosphere. In the Cloudroots project he is involved in high-frequency CO2 and water vapor isotope measurement.

    Hugo de Boer (PI)

    Utrecht University

    Hugo de Boer is assistant professor Global Environmental change at the Copernicus Institute of Sustainable Development at Utrecht University. His research expertise covers several interdisciplinary topics related to integrating theory and observations across the fields of plant ecophysiology, plant evolution and palaeo-ecology. Hugo is specifically interested in research questions related to how morphological and functional plant traits associated with water transport, transpiration and photosynthesis adapt under changing growth conditions. Hugo has experience with modelling leaf gas exchange by applying eco-evolutionary optimality principles, observing microscopic leaf traits (e.g. stomata, guard cells, cuticle cells, minor veins) and conducting greenhouse, growth chamber and field experiments with a focus on quantifying changes in leaf gas exchange in response to changes in atmospheric CO2 concentrations and humidity.

    Kevin van Diepen (PhD)

    Wageningen University

    My name is Kevin van Diepen and in December 2020 I started a PhD project that is nested within two chair groups of Wageningen University: the Horticulture and Product Physiology (HPP) group and the Meteorology and Air Quality (MAQ) group. The two chair groups reflect my dual character of plant physiology and micro-meteorology. The aim of my PhD project is to upscale dynamic plant photosynthesis and transpiration from the leaf towards the canopy. Plants in the field are often subject to rapidly fluctuating light intensities (sunflecks). The responses of photosynthesis and stomata to sunflecks are slow, resulting in loss of efficiency. However, these inefficiencies are often estimated on single leaves under laboratory conditions: thorough examinations of a plant’s response to sunflecks in the field are lacking. In my PhD project we will measure leaf- and canopy gas exchange in the field, characterise field sunflecks and use these field observations for dynamic modelling to assess how strongly leaf lab inefficiencies propagate to field canopies.

    Mary Rose Mangan is a PhD student in the Meteorology and Air Quality group at Wageningen University. Her research is focused on understanding the local and non-local drivers of evapotranspiration in semi-arid regions. This project combines data from the LIAISE measurement campaign and from numerical experiments with large eddy simulation to investigate how local surface heterogeneities impact the partitioning of the surface energy budget and the development of the atmospheric boundary layer over a range of spatial-temporal scales

    Arnold Moene (PhD adviser)

    Wageningen University

    Dr. Arnold Moene is associate professor in de Meteorology and Air Quality group of Wageningen University. Has a special interest in atmosphere-vegetation-soil interactions, and in particular in three aspects of those interactions: plant processes, atmospheric turbulence (both above and inside the canopy) and the role of vegetation in the surface energy and carbon balance. His research tools are the analysis of observational data, conceptual models and Large Eddy Simulation (full references).
    Apart from his research activities Arnold Moene is active in the field of education: he authored a text book on the interaction of atmosphere and vegetation, is an educational innovator, developing new tools and ways of teaching (e.g. and is programme director of the Wageningen Earth Sciences programmes (BSc Soil, Water, Atmosphere and MSc Earth and Environment).

    Utrecht University

    MSc. Robbert P.J. Moonen is a PhD student at Utrecht University under the Cloudroots NWO grant that Jordi Vilà and Thomas Röckmann received. He has gained his master’s degree at Wageningen University where he specialized in Meteorology and Air Quality. His main interests are the various turbulent exchanges between the land surface and the atmosphere, where he focusses on direct measurements of such fluxes. To this end, he uses tools like the Eddy-Covariance technique and Scintillometer method. Additionally, he is getting acquainted with high frequency measurements of CO2 and H2O isotopologues using laser spectroscopy. His ultimate goal to separate the respiration components from the vegetation and the soil at very short timescales by making flux measurements of these isotopologues. Such information will help to advance our understanding of plant dynamics and improve the parameterization of vegetation and soils in model simulations.
