    49 Note that the geographical coordinates of the requested spatial domain are nor perfectly uniform, and as a result it is not possible to represent the data as a regular grid. To overcome this problem, we perform an interpolation, although we preserve the native grid cell size of the model (0.75deg) for data representation. The R package `akima` provides a extremely fast interpolation algorithm by means of the `interp` function.

    69 In the following lines of code we plot the mean temperature field. In addition, we will also add to the map the point locations of the selected cities for which the time series will be represented. The R package `fields` provides many useful tools for spatial data handling and representation, including a world map that can be easily incorporated in our plots.
