Short summary
Short summary
Long-term observation sites have been established in six Austrian locations, covering major ecosystem types such as forests, grasslands, and wetlands. The purpose of these observations is to measure baselines for assessing the impacts of extreme climate events on the carbon cycle. The collected datasets include meteorological variables, soil temperature and moisture, carbon dioxide fluxes, and tree stem growth in forests at a resolution of 15–60 min between 2019 and 2021.

Short summary
Short summary
Forest soil is potentially an important source or sink of greenhouse gases (CO2, N2O, and CH4), but this is affected by soil conditions. We studied how land inclination and soil/litter properties influence the flux of these gases. CO2 and N2O were more affected by inclination than CH4; all were affected by soil/litter properties. This study underlines the importance of inclination and soil/litter properties in predicting greenhouse gas fluxes from forest soil and potential source–sink balance.

Short summary
In the subsaline reed wetland of Lake Neusiedl, we found the highest CH4 emissions in summer and via plant-mediated transport in each season. A clear diel cycle of CH4 emission was only identified for plant-mediated transport in summer. The isotopic source signature of CH4 differed between seasons, with the most 13C-depleted signature in fall. Desiccation reduced methanogenic diversity in the sediments and resulted in a marked increase in and dominance of the O2-tolerant Methanomicrobiales.
