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).
