The βeff dependence of the term that converts the absorption optical depth τabs into visible optical depth in Eq. 7, based on PSDs from SPARTICUS synoptic cirrus (blue squares) and anvils (black squares), and TC4 aged (red diamonds) and fresh (black diamonds) anvils, where the first size-bin is included (top, N(D)1 unmodified), or not included (bottom, N(D)1=0). The larger (smaller) symbols denote PSDs measured at a temperature colder (warmer) than −38°C. The curve-fit equations are for SPARTICUS synoptic cirrus (blue) and for TC4 aged and fresh anvils (red). The dashed lines are where the curve-fit equations are extrapolated (see Table 1).
