WITH THE LAUNCH OF SDO THAT CARRIES HMI -THE SUCCESSOR TO MDI- WE CAN ANTICIPATE BEING ABLE TO PRECISELY CHARACTERIZE P-MODES PROPERTIES THROUGHOUT SOLAR CYCLE 24. SUCH CHARACTERIZATION WILL LEAD TO COMPELLING INFERENCES OFTHE PHYSICAL PROPERTIES OF THE SOLAR INTERIOR AND THEIR EVOLUTION WITH SOLAR ACTIVITY. WE PROPOSE TO CARRY OVER TO HMI OBSERVATIONS OUR STATE-OF-THE-ART FITTINGMETHODOLOGY DEVELOPED AND APPLIED TO THE MDI OBSERVATIONS. WE WILL PROVIDE AN ALTERNATIVE TO THE STANDARD PIPE-LINE KNOWN TO HAVE PRODUCED BIASED ESTIMATES WHEN USED ON MDI OBSERVATIONS. THIS IS A NATURAL CARRY OVER OF OUR CURRENTEFFORTS FUNDED BY NASA GRANT NNX09AB15G (2008-2011: TIME SERIES MODE FITTING: IMPROVED METHODOLOGY USING LONG AND VERY LONG TIME SERIES). IN COLLABORATION WITH DR. EFF-DARWICH WE WILL THEN EXPLOIT THESE RESULTS USINGOUR BEST INVERSION TECHNIQUES AND FURTHER STUDY THE INTERNAL SOLAR ROTATION AND IT'S EVOLUTION OVER CYCLE 24.THE WORK PROPOSED HERE WILL DIRECTLY CONTRIBUTE TO OUR UNDERSTANDING OF THE SUN A KEY ELEMENT OF NASA STRATEGIC GOALS AND RESEARCH OBJECTIVES. MORE SPECIFICALLY IT WILL HELP US ANSWER NASA'S SCIENCE QUESTION HOW AND WHY DOESTHE SUN VARY?. IT WILL GREATLY IMPROVE THE SCIENTIFIC RETURN OF NASA'S SDO MISSION BY IMPLEMENTING A STATE-OF-THE-ART MODE FITTING ANALYSIS TOOL AND CARRY OVER FROM MDI WHAT WE HAVE LEARNED ABOUT MODE CHARACTERIZATION.
