Smoky marine boundary layer in southeast Atlantic

An image taken from the NASA P-3 aircraft while sampling a smoky, decoupled marine boundary layer over the southeastern Atlantic Ocean during the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) campaign. A thick deck of stratocumulus clouds is visible above the aircraft, which is flying through patchy "scud" cloud right at the lifting condensation level (LCL). The ocean surface is visible below. Smoke from biomass burning on the African continent, entrained from above, contributes to the hazy horizon.
