Modelling the diurnal and seasonal dynamics of soil CO2 exchange in a semiarid ecosystem with high plant–interspace heterogeneity

Autor: J. Gong, B. Wang, X. Jia, W. Feng, T. Zha, S. Kellomäki, H. Peltola

Publikováno v: Biogeosciences, Vol 15, Pp 115-136 (2018)

We used process-based modelling to investigate the roles of carbon-flux (C-flux) components and plant–interspace heterogeneities in regulating soil CO2 exchanges (FS) in a dryland ecosystem with sparse vegetation. To simulate the diurnal and sea

The carbon (C) cycling in semiarid and arid areas remains largely unexplored, despite the wide distribution of drylands globally. Rehabilitation practices have been carried out in many desertified areas, but information on the C sequestration capacit

Seasonality in a boreal forest ecosystem affects the use of soil temperature and moisture as predictors of soil CO2 efflux

Autor: S. Kellomäki, J. Silvola, S. M. Niinistö

Publikováno v: Biogeosciences, Vol 8, Iss 11, Pp 3169-3186 (2011)

Our objectives were to identify factors related to temporal variation of soil CO2 efflux in a boreal pine forest and to evaluate simple predictive models of temporal variation of soil CO2 efflux. Soil CO2 efflux was measured with a portable chamber i

Water and nitrogen processes along a typical water flowpath and streamwater exports from a forested catchment and changes after clear-cutting: a modelling study

Autor: A. Laurén, L. Finér, H. Koivusalo, T. Kokkonen, T. Karvonen, S. Kellomäki, H. Mannerkoski, M. Ahtiainen

Publikováno v: Hydrology and Earth System Sciences, Vol 9, Iss 6, Pp 657-674 (2005)

A two dimensional model, FEMMA, to describe water and nitrogen (N) fluxes within and from a forested first-order catchment (Kangasvaara in Eastern Finland) was constructed by linking the most significant processes affecting the fluxes of water, ammon
