Investigation of the Terrestrial HydrologicAl Cycle Acceleration (ITHACA)

Background  Funded by the Czech Science Foundation, “the Junior STAR grants aim to support excellent basic research and provide early career researchers with an opportunity to achieve scientific independence and build their own research group.” Starting in January 2022, ITHACA is an aspiring project that will bring together young researchers from various disciplines under the guidance of Dr. Yannis Markonis. The project team consists of experts in hydroclimatology (Martin Hanel, … Continue reading Investigation of the Terrestrial HydrologicAl Cycle Acceleration (ITHACA)

Review of GPM IMERG performance: A global perspective

Remote Sensing of Environment | Pradhan et al. [2021] Accurate, reliable, and high spatio-temporal resolution precipitation data are vital for many applications, including the study of extreme events, hydrological modeling, water resource management, and hydroclimatic research in general. In this study, we performed a systematic review of the available literature to assess the performance of … Continue reading Review of GPM IMERG performance: A global perspective

The Global Water Cycle Budget: A Chronological Review

Surveys in Geophysics | Vargas Godoy et al. [2021] Like civilization and technology, our understanding of the global water cycle has been continuously evolving, and we have adapted our quantification methods to better exploit new technological resources. The accurate quantification of global water fluxes and storages is crucial in studying the global water cycle. These … Continue reading The Global Water Cycle Budget: A Chronological Review

A cross-scale framework for integrating multi-source data in Earth system sciences

Environmental Modelling & Software | Markonis et al. [2021] Integration of Earth system data from various sources is a challenging task. Except for their qualitative heterogeneity, different data records exist for describing similar Earth system processes at different spatiotemporal scales. Data inter-comparison and validation are usually performed at a single spatial or temporal scale, which … Continue reading A cross-scale framework for integrating multi-source data in Earth system sciences

The rise of compound warm-season droughts in Europe

Science Advances | Markonis et al. [2021] Drought is one of the main threats to food security and ecosystem productivity. During the past decades, Europe has experienced a series of droughts that caused substantial socioeconomic losses and environmental impacts. A key question is whether there are some similar characteristics in these droughts, especially when compared … Continue reading The rise of compound warm-season droughts in Europe

Atmospheric circulation as a factor contributing to increasing drought severity in Central Europe

Journal of Geophysical Research: Atmospheres | Lhotka et al. [2020] Long‐lasting and severe droughts seriously threaten agriculture, ecosystems, and society. Summer 2018 in central Europe was characterized by unusually persistent heat and drought, causing substantial economic losses, and became a part of a several years long dry period observed across this region. This study assesses … Continue reading Atmospheric circulation as a factor contributing to increasing drought severity in Central Europe

The chemical composition of impact craters on Titan – I. Implications for exogenic processing

Astronomy & Astrophysics | Solomonidou al. [2020] We investigate the spectral behavior of nine Titan impact craters in order to constrain their composition. Past studies that have examined the chemical composition of impact craters on Titan have either used qualitative comparisons between craters or combined all craters into a single unit, rather than separating them … Continue reading The chemical composition of impact craters on Titan – I. Implications for exogenic processing

Increased future occurrences of the exceptional 2018–2019 central European drought under global warming

Scientific Reports | Hari al. [2020] Since the spring 2018, a large part of Europe has been in the midst of a record-setting drought. Using long-term observations, we demonstrate that the occurrence of the 2018–2019 (consecutive) summer drought is unprecedented in the last 250 years, and its combined impact on the growing season vegetation activities … Continue reading Increased future occurrences of the exceptional 2018–2019 central European drought under global warming

Representation of European hydroclimatic patterns with self-organizing maps

The Holocene | Markonis and Strnad [2020] Self-organizing maps provide a powerful, non-linear technique of dimensionality reduction that can be used to identify clusters with similar attributes. Here, they were constructed from a 1000-year-long gridded palaeoclimatic dataset, namely the Old World Drought Atlas, to detect regions of homogeneous hydroclimatic variability across the European continent. A … Continue reading Representation of European hydroclimatic patterns with self-organizing maps
