Fast Solar Wind Streams From the Sun to 1 AU During the Recent Solar Minimum

The origin and evolution of the solar wind from coronal holes is studied by characterizing the physical properties of the solar wind plasma (temperature, density, outflow velocity, and composition) with multi-spacecraft and ground-based observations. PFSS modeling is also used to confirm interpretation of the source regions and in wind-stream boundary mapping. We discuss the results for the fast solar wind from polar and low-latitude coronal-hole wind streams. We also compare the characteristics of these wind streams with results from the previous solar minimum.
