Streamers play an important role in the early stages of lightning and can be directly seen as sprite discharges. Many kinds of streamer discharge models developed at CWI are presented, using Particle-in-cell/Monte Carlo, fluid and hybrid codes from 1D to 3D. The codes are being improved and documented currently, to make them user-friendly and available on internet for potential users.
