An analysis pipeline for correlated global environmental noise

The high sensitivity required of gravitational wave detectors is such that environmental noise becomes a very important consideration. Local environmental noise may be partially or wholly eliminated by cross-correlating data from two geographically separated detectors; such a strategy will not, however, be able to eliminate environmental noise that is global in nature. Thus, the characterization of global environmental noise is an important task. We demonstrate an analysis pipeline to correlate measurements taken by globally separated physical environment monitoring instruments located at LIGO, VIRGO and The Australian National University (ANU), and successfully detect expected features.
