Abstract We present analysis of 17,043 proton kinetic-scale current sheets (CSs) collected over 124 days Wind spacecraft measurements in the solar wind at 11 samples s ?1 magnetic field resolution. The CSs have thickness, ?, from a few tens to one thousand kilometers with typical values around 100 km, or within about 0.1–10 ? p terms local inertial length, . found that density is larger for sma...
