The Extinction and Distance of the MBM Molecular Clouds at High Galactic Latitude

Based on the accurate color excess $E_{\rm G_{BP},G_{RP}}$ of more than 4 million stars and NUV,G_{BP}}$ 1 from \citet{2021ApJS..254...38S}, distance extinction molecular clouds in MBM catalog at $|b|>20^{\circ}$ are studied combination with measurement \emph{Gaia}/EDR3. The as well is determined for 66 clouds. ratio G_{BP},G_{RP}}/E_{\rm derived 39 them, which obviously larger implies small particles smaller extinction. In addition, scale height dust disk found to be about 100 pc becomes large anticenter direction due flaring.
