THE OBJECTIVE OF THIS PROPOSAL IS TO UNDERSTAND THE DYNAMICS OF WAVES GENERATED IN THE MULTI-SCALE BOUNDARY LAYERS OF MAGNETIC RECONNECTION (ELECTRON AND ION DIFFUSION REGIONS SEPARATRICES INFLOW AND EXHAUST REGIONS) AND THE ROLES AND EFFECTS OF THESE DYNAMICS ON THE MAGNETIC RECONNECTION PROCESS. THE RECENTLY-LAUNCHED MMS SPACECRAFT PROVIDING DETAILED HIGH-RESOLUTION PARTICLE AND FIELD DATA AT AND NEAR THE NIGHTSIDE (SYMMETRIC) AND DAYSIDE (ASYMMETRIC) RECONNECTION SITES HAVE SHOWN THAT PARTICLE DISTRIBUTIONS ARE HIGHLY STRUCTURED AND ACCORDINGLY LOCALIZED WAVES ARE OFTEN OBSERVED. SUCH DEFORMATIONS IN THE DISTRIBUTION FUNCTIONS CAN SUPPLY FREE ENERGY FOR WAVES. IN TURN PARTICLE DISTRIBUTIONS ALTER BY GENERATING WAVES AND/OR INTERACTING WITH WAVES. THEREFORE WAYES ARE CLOSELY RELATED TO AND CAN REPRESENT BOTH SPATIAL AND TEMPORAL VARIATIONS OF THE RECONNECTION PROCESSES. HOWEVER WE HAVE NOT YET DEVELOPED A COMPLETE CONTEXT OF THOSE WAVES IN ASSOCIATION WITH THE SPATIOTEMPORAL VARIATIONS OF THE RECONNECTION PROCESSES. HERE WE PLAN TO INVESTIGATE THE FOLLOWING SCIENTIFIC QUESTIONS VIA OUR PROJECT. QL) WHETHER OR NOT AND BY WHAT MEANS ARE WAVES RESPONSIBLE FOR RECONNECTION? Q2) WHAT ARE GENERATION MECHANISMS AND PROPERTIES OF WAVES IN MULTISCALE RECONNECTION SITES? Q3) CAN WAVE OBSERVATIONS RECONSTRUCT THE RECONNECTION GEOMETRY AND THE EVOLUTIONARY PHASES? WE USE BOTH IN-SITU MMS OBSERVATIONS AND PARTICLE-IN-CELL SIMULTIONS TO ADDRESS THE ROLES AND EFFECTS OF THE WAVES IN THE RECONNECTION PROCESS.
