 The Goddard lidar, hyperspectral and thermal, GLE-HT, airborne imaging system combines lidar, optical and thermal data to provide a comprehensive view of ecosystem structure and function. This system is uniquely suited for use with a variety of airborne platforms and can be used to measure plant species composition, plant functional types, biodiversity, biomass and carbon stocks, as well as plant growth. Additionally, it can be used to validate data from existing satellite missions and support NASA Earth science research. This article was authored by Von Lai, Paul M. Montesano, Kenneth J.
