In addition, to define the launch commit criteria, the correlation between 3kV/m and remote sensing parameter (ex: Thickness of cloud, ground E-field, Radar). So, NASA took many research and revise the criteria with professionals of atomosphic electricity, which are Radar, Airborn filed mill and ground base field mill network.
But JAXA don't have enough in-cloud data of our rocket range to revise. Modern main criteria to slip the launch opportunity is the thickness of cloud 1.8km with 0~-20degree Celsius. It have caused over half of our rocket launch. But we looked some case, when we thank no lightning risk.
So, we started the research of Triggered Lightning Launch Commit Criteria, last year. In this presentation, we explain the overall activity with the RAIJIN campain in this Feb, which are airborn field mill, X-band dual poralization radar, ground based field mill and Videosonde.. Also, propose the new criteria.
