Changes in the vertical profiles of RH (RH) associated with shallow convection under clean conditions [Cloud condensation number concentrations (CCN) 500 cm−3], moderate aerosol pollution (500 cm−3 < CCN ≤ 1,000 cm−3), and heavy aerosol pollution (CCN 1,000 cm−3). CCN, RH profiles, and convective occurrence are based on observations collected during the Green Ocean Amazon (GOAmazon) field campaign (SI Text). RH is reported in absolute differences.
