Analysis by GSI from ALOS-2 and ALOS-4 data of JAXA. These data were obtained based on the agreement with JAXA and through the activity of the SAR analysis working group of Coordinating Committee for Prediction of Volcanic Eruption. ALOS-4 data used in Fig.3 was provided by JAXA for calibration and validation. The numerical weather model was provided from JMA based on the agreement. Copyrights and CreditsCopyright.
