Climate change impacts the characteristics of the vegetation carbon-uptake process in the northern Eurasian terrestrial ecosystem. However, the currently available direct CO2 flux measurement datasets, particularly for central Siberia, are insufficie

Combining data from in situ measurements, remote sensing and models can provide new insights on global vegetation dynamics, specifically on the role of vegetation in the carbon and water cycles. Here we will demonstrate the benefits of combining Meto

Understanding the interactions between atmosphere and vegetation in changing climatic conditions is important so that we can predict the carbon sequestration potential of ecosystems. Helpful tools here are the terrestrial biosphere models (TBMs), sin

Climate change induced increases in surface temperatures in the northern high-latitudes have consequences for cryosphere conditions in the boreal zone (snow cover, soil freeze-thaw and permafrost). Cryosphere changes will in turn influence the biosph

Changes in the net carbon sink of boreal forests constitute a major source of uncertainty in the future global carbon budget and hence climate change projections1. The annual net ecosystem exchange of carbon dioxide (CO2) controlling the terrestrial

The effect of nutrient availability on plant growth and the terrestrial carbon sink under climate change and elevated CO2 remains one of the main uncertainties of the terrestrial carbon cycle. This is partially due to the difficulty of assessing nutr

Chlorophyll fluorescence (ChlF) takes place in green leaves of the plants during photosynthesis. It has therefore been proposed that ChlF can be used to track the photosynthetic activity of plants and the current possibility to observe sun-induced ch

Urban areas are a large source of carbon dioxide (CO2) to the atmosphere. Cities are seeking solutions to reduce the CO2 emissions and to achieve carbon neutrality. Thus, there is a growing interest in maximizing the carbon sinks of urban vegetation

The objective of this study was to assess the performance of the simulated start of the photosynthetically active season by a large-scale biosphere model in boreal forests in Finland with remote sensing observations. The start of season for two fores
