HRES O1280

...

 Soil type is a index taking an integer value between 1

...

and 7 over land points and 0 over sea points.  It is interpolated using a nearest neighbour method

...

. Differences occur due to the different selection of nearest points from the source grid.

HRES O1280

Soil type has been interpolated from the O1280 target grid to regular lat-lon grids at different resolutions using EMOSLIB and MIR. 

  • In general, the selection of the nearest neighbour point is in agreement with that returned by the ecCodes find_nearest routine
  • Many differences occur close to the coasts due to the absence of any land sea-mask processing by MIR
  • Typically, fewer than 1% of points are different
