Abstract
Using data acquired from NASA’s Magnetospheric Multiscale Mission (MMS), we determine the reconnection rates at dayside electron diffusion regions (EDRs) located at both the magnetopause and magnetosheath for multiple events. We collected and analyzed data from 7 events in each regime and used all spacecraft that captured the event (in most events, all 4 spacecraft). Reconnection rates are calculated using the reconnection electric field, EM. We apply an optimized boundary-layer transform to determine the reconnection electric field within the EDR. We measure a wide range of reconnection rates between 0.01-0.5. We were able achieve low enough errors in these rates to begin to identify possible trends connecting reconnection rates with other properties, such as inflow and outflow velocities within the EDR. By then utilizing readings from the Wind satellite for solar wind data, we found possible trends between the reconnection rate and the dynamic pressure and BZ. These findings suggest that the reconnection rates within dayside EDRs may link to both large- and small-scale phenomena.
