Scientific paper

Diagnostics of atmospheric "depth" in the chromosphere are made for several observing periods in active, coronal hole and quiet Sun regions. We track the coronal outflows from these regions to 1 AU using a ballistic travel time approximation and correlate the chromospheric quantities with counterpart in situ quantities from the same packets of plasma Recently, we1 have shown that derived diagnostic quantities correlate very strongly with solar wind velocity and inversely with the ratio of ionic oxygen composition (O7+/O6+). We extend this work to show that strong correlations exist between the state of the chromosphere and other in situ observables, including proton temperatures, alpha particle temperatures and alpha/proton ratios.
