Data products and their time coverageThe Service gathers SO2 data possibly related to volcano eruptions from measurements by a variety of satellite instruments and provides these in near-real time. In case of an "SO2 event" with exceptional SO2 concentrations, the Service issues a notification by email to users who have subscribed to this service. In addition, a data archive is made for case studies and validation of the notification criteria. Apart from SO2, the Service will also provide an aerosol flag or aerosol index.The table provides an overview of the data sets of SACS, with the time period covered by the data sets, as well as the data sets planned for use in the (near) future, listed per satellite instrument.
