importance of wetlands in the energy balance of an agricultural landscape
Energy fluxes, including net radiation, latent heat flux and sensible heat flux were determined on clear days during the vegetative period in four types of land cover: wet meadow, pasture, arable field, and an artificial concrete surface. The average net radiation ranged between 123� W� m⁻² at the concrete surface and 164� W� m⁻² at the wet meadow. The mean maximum daytime latent heat ranged between 500 and 600� W� m⁻², which corresponds to an evapotranspiration rate of about 0.2� g� m⁻²� s⁻¹ under the prevailing conditions of the wet meadow.
