The 3D structure and extinction law are studied for the Taurus, Orion, Perseus and California molecular clouds (MCs) based on the LAMOST and APOGEE spectroscopy. Extinctions are calculated from color excess derived from the Blue Edge methods. In combination with the distance from the Gaia,  a 3D extinction map and the structure of these MCs can be retrieved and the clouds that overlap in the sky area can be seperated. Also, the differences of extinction law in some MCs are studied from UV band to MIR band, the results demonstrate the interstellar environment varies in different MCs.


Zhetai Cao is a Ph.D. candidate in the Department of Astronomy, Beijing Normal University since 2020. He is interested in research topics related to interstellar medium, such as the extinction and the environment of the MCs.
