AB: Currently, analysis of synthetic seismograms and comparison to observed seismograms requires multiple tools to gather disparate sources of information and run various analysis routines. The SOSA application (Synthetic and Observed Seismogram Analysis) seeks to combine common tasks into a single software application. The tool enables scientists to retrieve observed seismograms accessible through a DHI (Data Handling Interface) and seismograms saved locally or accessible through an SRB (Storage Resource Broker). DHI implementations currently provide access to the IRIS DMC, the University of South Carolina, the Northern California Earthquake Data Center at Berkeley and the Southern California Earthquake Data Center at Caltech. Retrieved seismograms include the instrument signal and station information with instrument response. Seismograms retrieved from any source can be processed together, allowing easy comparison between synthetics and observed seismograms. Existing processing abilities include re-sampling, filtering, rotation, convolution/deconvolution with instrument response and correlation between seismograms. Scientists may save seismograms into SAC or mSEED format. The utility of the application will be demonstrated and future directions discussed.
