2. 1. Modeling the Seasonality of Carbon, Evapotranspiration and Heat Processes for Cold Climate Conditions

   Author : Sihong Wu; Per-Erik Jansson; Andreas Ibröm; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; net ecosystem exchange NEE ; sensible and latent heat fluxes; photosynthesis; respiration; nitrogen turnover; Scots pine forest; bare soil; cold climate; soil physical characteristics; CoupModel; GLUE; Other civil engineering and architecture; Övrig samhällsbyggnadsteknik och arkitektur;

   Abstract : The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. READ MORE

4. 2. Impact of cold climate on boreal ecosystem processes : exploring data and model uncertainties

   Author : Sihong Wu; Per-Erik Jansson; Annikki Mäkelä; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; net ecosystem exchange; sensible and latent heat fluxes; soil temperature; soil moisture; CoupModel; GLUE;

   Abstract : The impact of cold climate on physical and biological processes, especially the role of air and soil temperature in recovering photosynthesis and transpiration in boreal forests, was investigated in a series of studies. A process-based ecosystem model (CoupModel) considering atmospheric, soil and plant components was evaluated and developed using Generalized Likelihood Uncertainty Estimation (GLUE) and detailed measurements from three different sites.
