IRIS-EarthScope USArray Data Processing and Analysis Short Course, 2014
Northwestern University, Evanston, Illinois, United States

Mike Brudzinski (Miami University), Meghan Miller (University of Southern California), Rob Porritt (University of Southern California), Suzan van der Lee (Northwestern University), Andy Frassetto (IRIS), John Taber (IRIS)

The primary goal of this short course is to provide training in the foundations of seismic data processing for the next generation of young scientists. Our aim is to inspire the participants to become future leaders in developing more effective ways to handle data from large seismic datasets, such as the USArray. Participants will be selected into each short course by the program's steering committee based on the information provided in their applications. Travel and subsistence costs for participants in the short course will be covered by financial support from NSF through the "Collaborative Research: EarthScope Facility Operation and Maintenance (FY2008-FY2013) (USArray)" award to IRIS.

For more information contact Andy Frassetto.

The course will be held on the campus of Northwestern University, 30 minutes north of downtown Chicago along Lake Michigan. Information about travel and lodging will be posted in early summer.

Pre-Course: Unix and SAC Exercises (M. Brudzinski) Exercises based on server at Miami University, students use remote logins to work on a set of lessons relate to Unix, GMT, and SAC
