Soil type has been interpolated from the O1280 target octahedral reduced Gaussian grid to regular lat-lon grids at different target target 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
The plots show the differences with the contours chosen on a logarithmic scale to enhance the smaller differences. Differences smaller than 0.5% of the field range are not shown. Grid points where the absolute difference is greater than 50% of the maximum absolute difference are indicated with red (EMOSLIB greater than MIR) and blue (EMOSLIB less than MIR) filled circles.
