A study has been achieved by Jean-Michel Poggi, Michel Misiti, Yves Misiti and Bruno Portier (INSA de Rouen), in the context of a collaboration between AirNormand, Orsay University and INSA of Rouen. Two methods for spatial outlier detection have been considered: one based on the nearest neighbours weighted median and one based on kriging increments instead of more traditional pseudo-innovations. The two methods are applied to the PM10 monitoring network in Normandie (France) and are fully implemented in the Measurements Quality Control process.
