Hello Lingling, yes, this data is available. John Power will send you an email with additional information. Thank you, Cheryl Hello, I am a staff engineer working in Lamont of Columbia University. Currently, Our AVERT project requires Okmok Volcano's GPS data, processed and raw, and Cleveland's Seismogram (CLES) and webcam data; would you please give us a hint to the data in your organization? Or please refer us to the right data owners? Thnaks.
