Duration of the project: 9.10.2017 – 8.10.2020

Research project objective and methodology

The project objective is elaboration of the methodology for carbon balance modelling based on satellite Sentinel-1/2/3 data and insitu measurements of CO2 by chamber method, Leaf Area Index (LAI) by LI-COR 2200, soil moisture by TDR method (TRIME-FM), PAR (AccuPAR), biomass wet and dry (in the laboratory) surface temperature (IR radiometer, EXOTECH), soil temperature, for Biebrza wetlands under changing moisture, biomass and meteorological conditions.

The newest satellites Sentinel-1/2/3 will be applied for developing the models of soil moisture (Sentinel-1), LAI and biomass (Sentinel-2), and latent heat (LE) from energy budget applying surface temperature calculated from Sentinel-3 data. The soil-vegetation parameters will be obtained from satellite data using statistically derived models between in-situ and satellite data. Derived soil-vegetation parameters applying satellite data will be the input to carbon balance modelling. The carbon balance will be presented as temporal and spatial variation over the Biebrza wetlands. The assessed carbon fluxes and calculated latent heat and sensible heat (H) fluxes using surface temperature derived from Sentinel-3 will be validated applying measurements from the Eddy Covariance station which will be located as IGiK station in Biebrza Middle Basin.

Research project impact

The results will show how the moisture and biomass changes and meteorological conditions influence the carbon balance. It will give the indications for proper renaturalization of the wetland areas. The project is expected to have an important impact on scientific research into the link between remote sensing, plant physiology, agriculture and hydrology. The results will give strong input to the climate models and will give the answer how the biophysical parameters obtained from the newest satellite data has impact on carbon balance. The project will introduce the COPERNICUS climate service on national scale and in the future will integrate the scientific groups playing the role in climate change observations.
