Short summary
The Solfatara volcano (Italy), is monitored by a thermal infrared camera ground network handled by INGV. The dataset processed in this work consists of daily maximum temperatures time-series from 25 April 2014 to 31 May 2019. After a pre-processing, PSD's were calculated, filtering in [15–120] day band, to check if characteristic periodicities exist. Most of the periodicities are ascribable to ambient factors, while 18.16 and 88.71 days have a possible endogenous origin.
