Abstract in another language
The representation of sub-grid scale surface heterogeneities in numerical weather and climate models has been a challenging problem over more than the past decade. The project EVA-GRIPS (EVAporation at GRId and Pixel Scale) adds to the numerous studies on vegetation–atmosphere interaction processes through a comprehensive field campaign and through simulation studies with land-surface schemes and mesoscale models. The mixture of surface types in the test area in Eastern Germany is typical for larger parts of Northern Central Europe. The spatial scale considered corresponds to the grid scale of a regional atmospheric weather prediction or climate model and to the pixel scale of satellite images. Area averaged fluxes derived from point measurements, scintillomerter measurements and a helicopter borne turbulence probe were widely consistent with respect to the sensible heat flux. The latent heat flux from the scintillometer measurements is systematically higher than the eddy covariance data. Fluxes derived from numerical simulations proved the so-called mosaic approach to be an appropriate parameterization for subgrid heterogeneity.
