The Type III ELMy H-mode scenario offers an attractive alternative to the Type I ELMy H-mode scenario for baseline operation in ITER as it features small ELM energy losses and can coexist with detached divertor conditions. In JET, the Type III ELMy H-mode is characterized with small ELMs (<50kJ) and high ELM frequency (hundreds of Hertz) [1]. On the down side the Type III ELMy H-mode features lower confinement at H98 < 0.8 compared to H98 = 1 for Type I ELMy H-mode plasmas. In addition to the use of the regime as an operational scenario, the Type III ELMy H-mode regime is relevant for the back transition from H-mode to L-mode in ITER as it provides an intermediate step between the Type I ELMy H-mode and L-mode, and hence offers a possible recipe for a soft landing of the baseline H-mode scenario. The study of the transition from Type I to III ELMy H-mode is therefore important for both 1) the characterization of the confinement of the two regimes; and 2) the study of a pathway
