For several decades, in conjunction with ground observations, satellite remote sensing has been increasingly used to study Earth’s volcanoes, especially due to to low cost data, multi-spectral capability and global coverage, providing a wide range of spatial and temporal resolutions. Some satellite missions also offer a direct broadcast capability, making the data suitable for real-time applications and continuous monitoring. This session will highlight recent advances in the field of ground and satellite remote sensing of active volcanoes. For satellite observations a particular emphasis will be on the use of passive sensors, operating in the optical region (from VIS to IR) and with high observational frequency. Contributions covering all aspects of ground and satellite applications to volcanism (thermal activity, gas and ash emission, dynamics, etc.) from basic science to algorithm development and operational monitoring are welcome. Presentations describing new satellite observations and investigations for pre-, co- and post-crisis phases are solicited, together with innovative ideas for ground and satellite product validation. Besides, ground-based integrated EM and other geophysical methods will focus on the most approach for understanding and monitoring the dynamics of active volcanoes.
