Data Fusion Exercise: Anomalously low GLM flash extent density for the 28 April 2021 severe thunderstorm event

Introduction

This training session will build on data fusion methodologies from the Data Fusion section of the WOC Severe Course (updated in FY21). We will apply these data fusion concepts to a case with a lightning-dense thunderstorm. This type of thunderstorm may result in lower detection efficiency of lightning activity as observed from the GLM instrument. Data fusion techniques are utilized to help identify the GLM detection anomaly which can be applied to short-term forecast and warning operations of severe thunderstorms.

Training Session Options
