Neighbours Involved In the Interpolation

Taking real data from RR_24 for 2007 (April to December), the following graphs exhibit the numbers of neighbours available to compute a model value at each poit. The model value is based on only taking the available stations within 50 km distance. Average values are given. For some stations no model value could everr be generated (in red) this is either due to the absolute distance or anomalies that have not been further investigated.
