AbstractType III-L bursts constitute a class of type III bursts that are intense, complex, and of long duration at hectometric wavelengths. They are often associated with major flares and fast coronal mass ejections. Several observations suggested that the electron beams that produce these complex hectometric emissions could be accelerated and injected in the low or in the middle corona. In this study, we revisit the origin of these bursts by tracing the progression of the events from the low corona to the interplanetary medium. We show that type III-L features are related to sudden changes in the radio emission observed at metric and decametric wavelengths, in particular the onset of new emitting sources at positions that can be at large distances from the flare site.
