Radiometry of active volcanoes a user's manual / Andrew Harris.

Includes bibliographies and index.

"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"--

"Active volcanoes emit heat through lava flows and erupting vents. Remote measurements of heat emission from such active features can provide insights into the physical processes governing volcanic activity. Development of thermal remote sensing, and improved data-processing techniques, has enabled operational use of infrared instruments to perform volcano radiometry and to quantify the thermal flux from eruptions and volcanic systems, leading to better detection and measurement of volcanic activity"--
