pywasp.wasp.derive_gen_roughnesses#

pywasp.wasp.derive_gen_roughnesses(z0meso_from=None, z0meso_to=None, n=5)[source]#

Set generalized lib roughness lengths automatically

Parameters:

  • z0meso_from (numpy) – 1D array of mesoscale roughness length for each sector of source site in meter

  • z0meso_to (numpy, optional) – 1D array of mesoscale roughness length for each sector of target site in meter, by default None

Returns:

z0st (numpy) – 1D array of standard heights used for roughness length

Notes

The generalized standard values are set by selecting the percentiles corresponding to the number of intervals n. So for n=5, elements at 0, 0.2, … 1.0 etc are chosen.
