Raw (left) and model-adjusted (right) 15 min concentration means of different deployed SPS30 vs. 15 min concentration means of reference measurements given by the AEMS for PM2.5 in µg/m3: (Top) SPS30 deployed in AELCM003; (Middle) SPS30 deployed in AELCM004; and (Bottom) SPS30 deployed in AELCM005. Multiple linear regression is used for adjusting the raw LCS data.
