Distribution of Local Climate Zone Map


Dear Colleagues,

After interpolating the geographical static data generated by WUDAPT, namely the Local Climate Zone map of a city, it divides the urban areas into 17 classifications, how the WRF handles the map that has different fractions for the 17 zones (please note that the map has a higher resolution than that of the model grid)?

We have two assumptions:
a. according to the proportions of 17 zones in the high-resolution map to distribute them in the large grid of WRF.
b. only keep the local climate zone that occupies the most ratio.

Best regards,
I believe that WPS will determine the dominant land sue type and use that as the type in the WRF grid. So basically this is consistent to your assumption (b).
