The following describes work completed between April 2014 through February 2016. As in past years, Dr. Mayeda is a point of contact for LLNL’s colleagues in Florida and provides calibration, troubleshooting support, integration of new coda-related products, and processing for events and regions of interest. He has been responsible for integrating new coda-related products from ongoing BAA projects with his LLNL counterparts. Over the past two years Dr. Mayeda visited with Florida scientists to spot check and validate 1-D coda calibrations for the YSKP, BARM, and Zagros regions. In addition, a new region of interest was identified and will be the subject of ongoing research into the next fiscal year. Dr. Mayeda is consulting with LLNL scientists on how best to transition and test 2-D coda calibrations for the broader Middle East region using GT source spectra as constraints. This region is laterally very complicated and initial coda studies show that variance reduction could be significant if 2-D path and envelope shape are incorporated.
