Fig. 3: Firelighter BC causes positive radiative forcing and impacts the evolution of planetary boundary layer.
From: Air quality—climate forcing double whammy from domestic firelighters

a Averaged diurnal variation of Top-of-Atmosphere radiative forcing (ΔF in W m−2) over the entire firelighters case (Firelighter) and the reference summer case (Reference) with no pollution events observed; b diurnal variation of mixing layer (ML in m) during the firelighter and reference summer case.
