Ambient Air Monitoring in Karoo and Waterberg regions of South Africa
Carbon Monoxide and Sulfur Dioxide are among the major pollutants found in cities around the world. Local governments and councils frequently monitor air quality in remote locations with minimal pollutants in order to provide comparable figures.
The South African Weather Service (SAWS) have a responsibility in providing useful and innovative weather, climate and related products and services to their communities. In doing so, SAWS required two background stations to be installed in areas with little to no pollution.
Two ambient air monitoring stations were set up by SI Analytics (Pty) Ltd in two remote locations in South Africa: Karoo, the central high-plateau of South Africa and Waterberg, a mountainous province and one of the more regional areas in South Africa.
To obtain reliable measurements, SI Analytics (Pty) Ltd provided SAWS with the following analysers:
• Ecotech Gascal1100 Calibrator
• Ecotech Serinus 50 (SO2) Analyser
• Ecotech Serinus 40 (NO, NO2, NOx) Analyser
• Ecotech Serinus 30 (CO) Analyser
• Ecotech Serinus 10 (O3) Analyser
Data obtained from these four gas analysers enabled SAWS to measure very low level pollutant concentrations deployed in these remote and regional environments. This accurate and timely data helped SAWS model various scenarios for research and comparative purposes.
