Discerning the cows from the pasture: Quantifying and partitioning the NEE of a grazed pasture using animal position data

The applied standard gap filling and flux partitioning algorithm worked well for annual values, but results for shorter-term (daily to monthly) periods showed considerable uncertainties that can be attributed to the strong variability of cow presence in the flux footprint. However, the rotational grazing system in combination with the flux footprint distribution in the present study led to a reduction of the uncertainty for the annual scale.
