However, the relation between HI column density $N_{\\rm HI}$ and high-latitude dust emission observed by Planck has large-scale residuals at the level of $\\lesssim 20\\%$ on tens of degree scales. In this work, we improve HI-based dust templates in the north/south Galactic poles covering a sky fraction of $f_{\\rm sky}=13.5\\%/11.0\\%$ (5577/4555\\,deg$^2$) by incorporating data from ionized (HII) and molecular (H$_2$) gas phases.
