AB: 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.
