How reliable are crowd-sourced data in hydrology? Lessons learned from a citizen science experiment (2021)
Presentation / Conference
Klaus, J., Hannah, D., & Pan Chun, K. (2021, April). How reliable are crowd-sourced data in hydrology? Lessons learned from a citizen science experiment. Paper presented at EGU, Vienna

Crowd-sourcing of hydrological data with volunteering citizen scientists has the potential to overcome severe data limitations in space and time. However, several aspects on the reliability, quality, and value of crowd-sourced data are under debate.... Read More about How reliable are crowd-sourced data in hydrology? Lessons learned from a citizen science experiment.

A novel and robust procedure for upscaling sap velocity data based on the species-specific role of DBH and slope for explaining tree-to-tree variability (2021)
Presentation / Conference
Schoppach, R., Pan Chun, K., He, Q., Ginevra, F., & Klaus, J. (2021, April). A novel and robust procedure for upscaling sap velocity data based on the species-specific role of DBH and slope for explaining tree-to-tree variability. Paper presented at EGU, Vienna

Multi-species forests display a substantial tree-to-tree variability in transpiration induced by various vegetation and landscape characteristics. However, how to model transpiration accounting for tree-to-tree variability still needs to be developed...

Detecting drought conditions related to vegetation at west continental Europe based on variations from the North and Caspian Seas (2021)
Presentation / Conference
Xu, B., He, Q., Pan Chun, K., Klaus, J., Schoppach, R., & Yetemen, Ö. (2021, April). Detecting drought conditions related to vegetation at west continental Europe based on variations from the North and Caspian Seas. Paper presented at EGU, Vienna

Teleconnections relate regional pressure patterns to local climate anomalies, influencing the variation of vegetation patterns. Over west continental Europe, droughts have been widely investigated with persistent low-frequency atmospheric circulation...

Assessment of multiple stable isotopes for tracking regional and organic authenticity of plant products in Hesse, Germany (2021)
Journal Article
Gatzert, X., Chun, K. P., Boner, M., Hermanowski, R., Mäder, R., Breuer, L., …Orlowski, N. (2021). Assessment of multiple stable isotopes for tracking regional and organic authenticity of plant products in Hesse, Germany. Isotopes in Environmental and Health Studies, 57(3), 281-300. https://doi.org/10.1080/10256016.2021.1905635

As demand for regional and organically produced foodstuff has increased in Europe, the need has arisen to verify the products’ origin and production method. For food authenticity tracking (production method and origin), we examined 286 samples of whe...

Robust decadal variations in ENSO diversity, and its impact on future scenarios (2021)
Working Paper
Dieppois, B., Capotondi, A., Pohl, B., Pan Chun, K., Eden, J., & MOnerie, P. Robust decadal variations in ENSO diversity, and its impact on future scenarios

El Niño-Southern Oscillation (ENSO) shows a large diversity of events, whose modulation by climate variability and change, and their representation in climate models, limit our ability to predict their impact on ecosystems and human livelihood. Here,... Read More about Robust decadal variations in ENSO diversity, and its impact on future scenarios.

Hydro-climatic changes of wetlandscapes across the world (2021)
Journal Article
Åhlén, I., Vigouroux, G., Destouni, G., Pietroń, J., Ghajarnia, N., Anaya, J., …Jarsjö, J. (2021). Hydro-climatic changes of wetlandscapes across the world. Scientific Reports, 11(1), 13400. https://doi.org/10.1038/s41598-021-81137-3

Assessments of ecosystem service and function losses of wetlandscapes (i.e., wetlands and their hydrological catchments) suffer from knowledge gaps regarding impacts of ongoing hydro-climatic change. This study investigates hydro-climatic changes dur... Read More about Hydro-climatic changes of wetlandscapes across the world.

On the laboratory calibration of dielectric permittivity models for agricultural soils: Effect of systematic porosity variation (2021)
Journal Article
Pan, X., Han, Y., Chun, K. P., Zhang, J., Ma, D., & Gao, H. (2021). On the laboratory calibration of dielectric permittivity models for agricultural soils: Effect of systematic porosity variation. Vadose Zone Journal, 20(1), Article e20096. https://doi.org/10.1002/vzj2.20096

Dielectric techniques are fundamental methods for measuring soil water content, and they commonly rely on the conventional laboratory calibration of the dielectric permittivity models between a dielectric constant and water content. As a non-negligib... Read More about On the laboratory calibration of dielectric permittivity models for agricultural soils: Effect of systematic porosity variation.
