We’re proud to share the newest publication introducing SoFi RT, which applies the novel AXA approach for total PM source apportionment: “Implementation of real-time source apportionment approaches using the ACSM–Xact–Aethalometer (AXA) setup with SoFi RT: the Athens case study”.
This study marks the first-ever application of the AXA setup integrated with SoFi RT for real-time source apportionment. By integrating multiple instruments into one coherent analysis pipeline, SoFi RT opens new possibilities for faster, more comprehensive source apportionment — supporting better science, decision-making, and pollution mitigation. Importantly, the results compare well with the traditional rolling PMF approach, demonstrating that real-time analysis can deliver both speed and reliability without compromising scientific robustness.
