چکیده
Abstract. Long et al. (2021) conducted a detailed study of possible interferences in measurements surface O3 by UV spectroscopy, which measures the transmission ambient and O3-scrubbed air. While we appreciate careful work done this analysis, there were several omissions, one case, type scrubber used was misidentified as manganese dioxide (MnO2) when fact it chloride (MnCl2). This misidentification led to erroneous conclusion that all UV-based instruments employing solid-phase catalytic scrubbers exhibit significant positive artifacts, whereas previous research found not be case MnO2 types. study, our results, confirm substantial bias an MnCl2 scrubber, replication earlier with no humidity correction is needed.

The paper propose a new methodology to quantify the contributions from wild fires along the path of backtrajectories. The authors use this and measurements on 3 different stations to understand how the aerosol ages, what and how much is emitted of different pollutants among other things. The method, however, is poorly explained or debated and gave me doubts if it is really correct or not. Engli...

The manuscript describes some impacts of eastern European biomass burning on some ambient air monitoring stations located in Finland in the spring and summer of 2006. The paper follows the familiar model of monitoring and interpretive analysis. In my opinion, however, there is a difference between monitoring, monitoring with valueadded analysis, and research. I believe ACP should be an outlet f...

This paper is concerned with presenting methods to study transport and lifetime of both gases and particles originating from biomass burning. It is beyond doubt that biomass burning has a detrimental impact on air quality on both the smaller and larger scale, and studying the fate of biomass burning plumes can provide useful insights within this area of research. As pointed out by the authors, ...
