Parameters aggregation processlinked to spatial resolutionSurface parameters are aggregated same way (linear combination), in simple case, forexample, for the C3 patch (PAR_VAL is « parameter value »):PAR_VAL_C3(POINT) =0.4*FRAC_NAT(COV1)*FRAC_C3(COV1)*PAR_VAL(C3,COV1) +0.35*FRAC_NAT(COV2)*FRAC_C3(COV2)*PAR_VAL(C3,COV2) +0.25*FRAC_NAT(COV3)*FRAC_C3(COV3)*PAR_VAL(C3,COV3)If PAR_VAL calculation is independent of LAI or height of trees,PAR_VAL_C3(POINT) = FRAC_C3(POINT) * PAR_VAL(C3)Linear calculationFrom correspondence tableParameters are averaged on all covers present in grid point and weighted with :Fraction of cover in grid point * fraction of nature in cover * fraction of patch in cover
Parameters aggregation processlinked to spatial resolution: variantsParameters can also be weighted with other coefficients than the fraction oftile « NATURE », according to their field of application: VEG, LAI, fraction of TREE / CONI / EVER, fraction of TOWN, fraction of building,fraction of street.The mean applied is not always arithmetic, it can be : opposite : opposite of parameters values are added and the mean is the totalnumber of added values on this sum.It concerns RSMIN (minimal stomatal resistance).inverse of square logarithm: 1 / ln(dz/PAR_VAL)**2 is the averaged quantity.DZ is the height of the first model mass level or 20m by default.It concerns Z0 (roughness lenght).
