AirQualityStationEoICode	EoI code of air quality measurement station (as in AirBase).	string
SamplingPoint (PK)	Inspire identifier (LocalId) of sampling point, given by data provider.	string
AirPollutantCode (PK)	Air polluting substance, level of which is measured and reported to the EEA (see "notation" in Data Dictionary: http://dd.eionet.europa.eu/vocabulary/aq/pollutant).	string
