In the sentence beginning ‘The first objective of this study’ in this article under Sect. 3.1. Conditions for self-sustained smoldering, quotation marks were added for the x symbol. It should have been read as ‘At a wind speed of 1.5 m/s, some of the samples with low SAV transitioned to flaming, as indicated by the red X below the respective pie marker in Fig. 3b’. Also, under Sect. 3.2. The effect of spacing, square boxes were added instead of the approximately equal symbol. It should have been read as at about t = 1400 s, the sample transitioned to flaming (starting from the trailing edge of the sample), which lasted until t = 1550 s, as indicated by the sharp decrease in measured mass loss. The combustion products volumetric fractions quickly increased during the ignition phase. The CO sensor of the gas analyzer was often close to saturation during ignition, and it needed about 60 s to adjust after the igniter was turned off. After t = 500 s, the CO concentration steadily increases until 1400 s, while the HC volumetric fraction is almost constant, and no appreciable CO₂ was detected. The original article has been corrected.
