SatFC-G: Introduction to the GLM

About the GLM »
Introduction

This lesson describes the need for real-time lightning information and the capabilities of the Geostationary Lightning Mapper (or GLM). GLM flies on board the new-generation GOES-R satellites as the first operational lightning detector in geostationary orbit.

Upon completion of the lesson, learners will be able to:

  • Describe the GLM’s benefits and capabilities
  • Describe the main components of the cloud-to-ground lightning flash life cycle
  • Differentiate between how lightning is observed by space-based and ground-based detection systems
  • Outline the process of converting GLM observations to a lightning flash product
  • Describe how GLM observations will help improve situational awareness and support severe weather warning decisions
  • Explain how GLM observations will improve warnings of impending lightning hazards
  • Highlight other applications that will benefit from GLM observations
