Thermal Remote Sensing of Active Volcanoes
A User's Manual

Encapsulating over one hundred years of research developments, this book is a comprehensive manual for measurements of Earth surface temperatures and heat fluxes, enabling better detection and measurement of volcanic activity. With a particular focus on volcanic hot spots, the book explores methodologies and principles used with satellite-, radiometer- and thermal-camera data. It presents traditional applications using satellite and ground based sensors as well as modern applications that have evolved for use with hand-held thermal cameras and is fully illustrated with case studies, databases and worked examples. Chapter topics include techniques for thermal mixture modelling and heat flux derivation, and methods for data collection, mapping and time-series generation. Appendices and online supplements present additional specific notes on areas of sensor application and data processing, supported by an extensive reference list. This book is an invaluable resource for academic researchers and graduate students in thermal remote sensing, volcanology, geophysics and planetary studies.

Andrew Harris is a professor at Université Blaise Pascal (Clermont Ferrand, France) and holder of the Chaire d'Excellence for the Auvergne region. He is a member of the Remote Sensing Society, IAVCEI and AGU and has worked with a variety of ground- and satellite-based thermal data sets, having deployed experiments at active volcanoes in Africa, Europe, Central America, South America and Hawaii. Dr Harris has published over 130 publications in international scientific journals dedicated to thermal remote sensing and volcanology. His work has been recognised by several awards, including IAVCEI's Wager medal (2004) and the University of Hawai'i Regents' Medals for both excellence in research (2003) and teaching (2005).
