HRES - O1280

  • Temperature at 2m has been interpolated from the O1280 target grid to regular lat-lon grids at different resolutions
  • Differences between MIR and EMOSLIB generally lie between +/-5K.
  • In general, more than 95% of points differ by less than+/-1K.
  • 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.  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 circle
