cds-question@unistra.frmolecular-cloudsstellar-distanceextinctionvisible-astronomyultraviolet-astronomyBased on the accurate color excess E_GBP,GRP_ of more than 4 million stars and the E_NUV,GBP_ of more than 1 million stars from Paper I (Sun+, 2021ApJS..254...38S), the distance and extinction of the molecular clouds (MCs) in the Magnani-Blitz-Mundy (MBM; 1985ApJ...295..402M) catalog at |b|>20{deg} are studied in combination with the distance measurement of Gaia/EDR3. The distance, as well as the color excess, is determined for 66 MCs. The color excess ratio E_NUV,GBP_/E_GBP,GRP_ is derived for 39 of them, which is obviously larger and implies more small particles at smaller extinction. In addition, the scale height of the dust disk is found to be about 100 pc and becomes large at the anticenter direction due to the disk flaring.2021ApJS..256...46Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/256/46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)VII/7 : Lynds' Catalogue of Dark Nebulae (LDN) (Lynds 1962)J/A+AS/103/541 : Arcetri Catalogue of H2O Maser Sources (Brand+ 1994)J/A+A/327/325 : Distances of molecular cloud (May+, 1997)J/A+A/383/631 : Catalogue of dust clouds in the Galaxy (Dutra+, 2002)J/ApJ/623/897 : Reddening and extinction at high gal. latitude (Larson+, 2005)J/PASJ/57/917 : CO clouds in southern Galactic Warp (Nakagawa+, 2005)J/ApJ/706/727 : Distance and mass of Infrared Dark Clouds (Marshall+, 2009)J/ApJ/699/1153 : Kinematic distances to GRS clouds (Roman-Duval+, 2009)J/PASJ/63/S1 : Atlas and cat. of dark clouds based on 2MASS (Dobashi+, 2011)J/ApJS/212/2 : Giant clouds in the 4th Galactic quadrant (Garcia+, 2014)J/ApJ/786/29 : Catalog of distances to molecular clouds (Schlafly+, 2014)J/ApJ/834/57 : MW molecular clouds from ^12^CO (Miville-Deschenes+, 2017)J/ApJ/861/153 : Ultraviolet Extinction in the GALEX Bands.
