Annotation of project:
Freshwaters are significant sources of methane (CH4) to the atmosphere but streams and rivers have only recently come into focus. The high spatiotemporal variability of fluvial CH4 ebullition, a major pathway of CH4 emission, hinders our ability to estimate the contribution to the global CH4 budget. Hence the proposed project aims to decipher the magnitude and drivers of CH4 ebullition, its production, and the involved biological processes in stream sediments. Four sampling campaigns over one year in six streams (three in the Czech Republic and three in Austria) will be conducted. In the second year, laboratory incubations to study environmental drivers of CH4 production in stream sediments are planned. In parallel, field measurements of CH4 fluxes from various components of a floodplain forest ecosystem together with the eddy covariance data analyses will be done to quantify the contribution of aquatic versus terrestrial habitats to the landscape CH4 fluxes. The obtained results will significantly improve the estimation of total CH4 fluxes from streams.

Annotation of project:
A north-south gradient combined with selected species adapted to different growing conditions allows evaluating the performance of the tree species, under climate change (CC) conditions. Established models explaining the relationships among environmental factors, wood structure and properties, can be used to predict responses to CC scenarios. Such information is critical for predicting wood availability and flows in the forest-based bioeconomy. The main objective is to study the effects of CC on productivity, structural, physical and mechanical properties of selected pine and oak species adapted to temperate and sub-Mediterranean growing conditions in Slovenia and the Czech Republic. The proposal is divided into five work packages (WP) addressing the following objectives. WP1: tree-ring characteristics and wood anatomical features, WP2: physical and mechanical properties of wood, WP3: wood properties prediction models in relation to CC scenarios, WP4: impact on the bioeconomy. WP5 foresees tasks and activities related to communication and dissemination of the project's results.

Annotation of project:
The project concentrates on an extensive validation process of state-of-the-art climate models and downscaling methods based on various reference datasets of climate observations, to identify their strong and weak points and then apply the gained knowledge to improve the reliability of climate projections in Central Europe (represented here by Poland, Czech Republic, part of Slovakia and eastern Germany). A special attention will be paid to atmospheric circulation (as the main weather driving factor) with an emphasis on its representation in climate models. Occurrence of different circulation types and their intensity is important for the origin of significant weather events and extremes. Therefore, the detailed knowledge concerning the ability of climate models to assess impacts of atmospheric circulation and its long-term trends will be a key to better understand and interpret future climate projections.

Annotation of project:
Main goal of the project is to describe the relationship between planetary boundary layer (PBL) height and atmospheric aerosol (AA) in vertical profile. The project plans to use a unique infrastructure including 250 m tall tower at a Central European rural background site. Chemical and physical properties of AA will be measured by state-of-the-art aerosol instrumentation at two different heights (ground and 230 m) with high-time resolution, depending on daily and seasonal cycles of PBL height, chemical composition and changes in physical parameters of AA alongside radiative forcing and the concentration of AA nanoclusters. This will provide crucial knowledge of the changes of atmospheric properties within and above PBL and thus help to reduce the current uncertainties in atmospheric aerosol forcing of the Earth's climate system. Furthermore, it will provide important insights into the representativeness of conventional ground-based measurements of AA properties, which may lead to their re-evaluation in relation to vertical measurements and in combination with satellite measurements.

Annotation of project:
The knowledge of the turbulent energy (latent and sensible heat) fluxes is critical in research fields such as meteorology, hydrology and ecophysiology. Eddy covariance (EC) is widely used technique for their measurements, however, a recalcitrant problem is so called energy balance non-closure representing on average 15% across more than 900 sites worldwide. Alternative methods for energy fluxes determination are e.g. flux variance (FV) and surface renewal (SR). We aim to revise the FV and SR methods in a single framework emphasizing a clear physical interpretation of all methodological aspects. Following previous studies documenting better, yet unexplained, energy balance closure of SR as compared to EC, we aim to analyze the physical causes of this phenomena. In line with the most recent studies indicating the important role of large eddies in the EC non-closure problem, we suggest that studying energy balance closure within the frame of FV and SR methods that relies largely on large coherent eddies can provide further links in this still not fully understood research topic.
