We analyzed data from 19 eddy covariance flux tower sites across the Netherlands, representing six different land cover types in the same climatic zone. Through regression analysis, we identified the key drivers of these flux dynamics. Our results show that land cover partly explains the variability in daily and midday turbulent fluxes.
We found that:
- Evaporation dynamics from grassland, peatland swamp, and cropland sites are mainly influenced by energy availability.
- Forest evaporation is primarily driven by water availability.
- Urban evaporation is affected by both water availability and exchange efficiency.
- Open water evaporation is predominantly influenced by exchange efficiency.
Interestingly, we observed that the sensible heat flux is less sensitive to land cover type, indicating that the land-atmosphere interface plays a significant role in regulating sensible heat exchange.
Our findings contribute to a better understanding of the complex dynamics of evaporation over different land cover types
