Datenqualitätsziele der EU-Richtlinien
Gute Datenqualität und hohe Verfügbarkeit der Daten sind in einem Luftqualitätsmessnetz wesentlich, um die Datenqualitätsziele der EU-Richtlinien zu erreichen.
Um sicher zu stellen, dass die Daten ausreichend genau, zuverlässig und vergleichbar mit anderen Messnetzen sind, müssen die Massnahmen zum Qualitätsmanagement durchgängig im gesamten Messnetz angewandt werden.
