Figure 8: Altitude profiles of the shortwave absorbing powers Pabs attributable to black carbon and iron oxide.
From: Anthropogenic iron oxide aerosols enhance atmospheric heating

(a) The Pabs(BC) and Pabs(FeOx), whereas b shows mean Pabs(FeOx)/Pabs(BC) ratio. Filled and open circles (triangles) represent the mean values in each altitude range (dry PBL air) for the bare and coated particles, respectively. In a, error bars represent the variability in Pabs estimated from the ±1σ value of the 1-min mass concentration data.
