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 |
