Concept URI	http://dd.eionet.europa.eu/vocabulary/aq/aggregationprocess/P1Y-WA-dc
Preferred label	1 year weighted average data capture
Definition	The data capture for multi day sampler based data types integrated over an averaging period is calculated as the proportion of valid measurement time (at a minimum seconds- alternatively decimal hours or days) relative total measured time in the averaging period- expressed as an percentage. The data capture for a given averagingperiod shall be calculated as follows: Data capture = _i DCi * Nvalid-i / _i Ni * 100 % where DCi = the data capture (in %) of the valid sample I- that is- the effective sampling time in a measuring period Nvalid-i = the number of hours in the valid sample i (validity flag sample > 0) Ni = number of hours in sample i
