I have brought six SPSA sensor system to Addis Ababa. Tesfaye Mamo, staff of the department of Physics at Addis Ababa University, will collocate them over the coming weeks at some ground measurement locations of the MAIA mission in Addis Ababa.
Earlier, we tested the SPSA in Arba Minch, as well as at Ethiopian Meteorology Institute stations of Addis Ababa and Adama. Part of this data has been published. The new sensor systems will collect PM2.5 data next to Purple Air sensors (commercial low-cost sensors). Comparison of the data will show whether the SPSA sensor systems can produce data as reliable as (or even more reliable than) the Purple Air sensors. If this is the case, air quality monitoring capacity in Ethiopia could be increased with locally constructed sensor systems rather than commercial ones from outside. This would result both in cost reduction and local expertise increase.
