For near surface
parameters the distinction between land and sea points may be
crucial, for example for 2 m temperature, precipitation or 10 m
wind. As mentioned above (2.3.2.), the model land-sea mask defines
land and sea model gridpoints. Due to the limited horizontal grid
resolutions users should be careful in using the direct model
output near coastlines, small islands and narrow peninsulas as the
marine influence if often over-estimated. Also here statistical
interpretation schemes might be beneficial, in particular for the
temperature forecasts.
