Interpolation of temperature at 2m is affected by the changes to:
- the land sea-mask processing
- the default interpolation method
- the distance computation and selection of nearest points
HRES - O1280
Temperature at 2m has been interpolated from the O1280 target grid to regular lat-lon grids at different resolutions
- Differences For the cases shown here, differences between MIR and EMOSLIB generally lie between +/-5K.
- In general, more than 95% 99.55% of points differ by less than +/-1K0.5 K.
- Largest The largest differences occur close to the coasts and in areas of steep orography where the gradient of the 2m temperature field changes most rapidly
The plots show the differences with the contours chosen on a logarithmic scale to enhance the smaller differences. 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
