As for the interplanetary shocks, the study of the Langmuir Waves (LW) associated with interplanetary in-situ type III bursts is an important science goal for RPW. For the same reasons, it was decided to implement an in-situ Type III detection algorithm which is also described in this document.

The automatic detection algorithm for in-situ Type III burst LW is producing the so-called SBM2 data for Selected Burst Mode 2.
