Average Doppler shift in the quiet Sun at disk centre of various TR and coronal ions measured from SUMER and EIS spectra. Positive values indicate red shifts (downflows) while negative values indicate blue shifts (upflows). Solid and dashed lines respectively represent fourth and and sixth order polynomial curves by-eye fitted to the combination of the measurements obtained in this work and those of Teriaca et al. (1999a).
