Selection of daily distance variations (2002-2021) at Mount Etna

Selection of daily distance variations between two pairs of GPS benchmarks (EMGL-EMAL and EMEG-ESLN) located in the western flank of Mt. Etna during 2002-2021. (Format: two GPS daily distance variations separated by comma in meters) <br> <em>The authors acknowledge the Technicians and Technologists of the INGV - Osservatorio Etneo (GPS Permanent Network) for enabling and improving the acquisition of raw GNSS data. We are grateful to F. Cannavò that provided distance daily variations between two pairs of GPS benchmarks during the time periods when the solution is not available in Literature. </em>
