Data gaps will leave scientists ‘in the dark’: How load shedding is obscuring our understanding of air quality

“…Given that air pollution is a major global, African and South African human health problem, the need for accurate air quality data is paramount. SAAQIS data are used by researchers in different fields of science including epidemiology 18 , chemistry 19 , and atmospheric science 20 Data gaps reflected by the number of 'blank' readings (shown as 'NaN') and likely incorrect recordings after load shedding need to be communicated to all users of SAAQIS via the website. These gaps will affect the collection of continuous data for time series and other methodological uses, affecting the accuracy of the data.…”
