The FLUXNET2015 dataset and the ONEFlux processing pipeline for eddy covariance data

The FLUXNET2015 dataset provides ecosystem-scale data on CO2, water, and energy exchange between the biosphere and the atmosphere, and other meteorological and biological measurements, from 212 sites around the globe (over 1500 site-years, up to and including year 2014). These sites, independently managed and operated, voluntarily contributed their data to create global datasets. Data were quality controlled and processed using uniform methods, to improve consistency and intercomparability across sites. The dataset is already being used in a number of applications, including ecophysiology studies, remote sensing studies, and development of ecosystem and Earth system models. FLUXNET2015 includes derived-data products, such as gap-filled time series, ecosystem respiration and photosynthetic uptake estimates, estimation of uncertainties, and metadata about the measurements, presented for the first time in this paper. In addition, 206 of these sites are for the first time distributed under a Creative Commons (CC-BY 4.0) license. This paper details this enhanced dataset and the processing methods, now made available as open-source codes, making the dataset more accessible, transparent, and reproducible.Peer reviewe

Radiation regime of spruce forest stand in the locality Bílý Kříž in Moravian-Silesian Beskydy Mountains

Following radiation characteristics were used to describe the radiation regime of the study forest site: a)transmitation of the spruce stand for PAR, b)reflectation of spruce stand for PAR, c)absorbation of spruce stand for PAR

Strategie Ministerstva životního prostředí k adaptačním opatřením v krajině v souvislosti s klimatickými změnami - ekofyziologie rostlin‚ pravděpodobné dopady na lesy a lesní hospodářství:Rešerše reprezentativních výzkumných výstupů zaměřených na krajinnou ekologii a biodiverzitu ve vztahu k vývoji klimatu na území ČR

Zpráva popisuje hlavní směry výzkumů v souvislosti s klimatickými změnami. Ekofyziologický výzkum byl orientován zejména na vliv navyšování koncentrace CO2 v atmosféře, stres suchem, teplem a měnící se ozářeností. Výzkum dopadů klimatické změny na lesní ekosystémy v ČR je založen na dlouhodobém monitoringu stavu porostů a aktivizace škůdců a nemocí, na ekofyziologickém výzkumu a experimentech pěstování lesních dřevin ve zvýšené koncentraci CO2. Jsou uvedeny významné rizikové faktory

Global climate change and regional impacts on forests in Beskydy Mts

Beskydy Mts. is a region with a relatively high probability of expansion of serious Norway spruce stand fade-away types which are accompanied with gradations of insect pests and fungi pathogens as mortal factors. The study is focused on individual factors of change of forest trees growth conditions: increased CO2 concentration, drought, temperature, extreme weather, dimming effect, nitrogen deposition. Furthermore, it recapitulates briefly current state of forest stands in Beskydy Mts. and it defines procedure of estimation of spruce stand degradation risks
