Column heIght during Etna expLosive eruptiOn (CIELO) [v2]

The Column heIght Estimation by visibLe calibrated camera during eruptiOns at Etna (CIELO) dataset provides time series of volcanic column height measurements at the South East Crater (SEC) of Etna, derived from visible calibrated webcam images. The dataset covers 42 ash emission episodes spanning from 2015 to 2021. All data are also collected in an SQLite database (CIELO.db). This is version 2 of the dataset. It adds, for each event, the original webcam frames used as input. It also provides the database as a plain-text SQL dump (CIELO.sql). Data and results are unchanged from version 1.
