Short summary
This study explores how aerosols affect atmospheric heating over African easterly waves (AEWs). Using data from NASA's aircraft and outputs of reanalysis models, the research focuses on days with both Saharan dust and AEWs. Using a radiative transfer model, the study reveals significant differences in heating rates, emphasizing challenges in accurately representing aerosol effects in the atmosphere and underscoring the need for improved aerosol representation in weather models.
