     abstract = "{Mascon modeling is used in this paper to produce the mass flux solutions
        in the Tibetan Plateau. In the mascon modeling, the pseudo
        observations and their covariance matrices are derived from the
        GRACE monthly gravity field models. The sampling density of the
        pseudo observations is determined based on the eigenvalues of
        the covariance matrices. In the Tibetan Plateau, the sampling
        density of per 1.5{\textdegree} is the most appropriate among
        all choices. The mass flux variations from 2003 to 2014 are
        presented in this paper, which show large mass loss (about -15.5
        Gt/year) in Tianshan, North India, and Eastern Himalaya, as well
        as strong positive signals (about 9 Gt/year) in the Inner
        Tibetan Plateau. After the glacier isostatic adjustment effects
        from Pau-5-AUT model are removed, the mass change rates in the
        Tibetan Plateau derived from CSR RL05, JPL RL05, GFZ RL05a, and
        Tongji-GRACE02 monthly models are -6.41 {\ensuremath{\pm}} 4.74
        Gt/year, -5.87 {\ensuremath{\pm}} 4.88 Gt/year, -6.08
        {\ensuremath{\pm}} 4.65 Gt/year, and -11.50 {\ensuremath{\pm}}
        4.79 Gt/year, respectively, which indicate slight mass loss in
        this area. Our results confirm that mascon modeling is efficient
        in the recovery of time-variable gravity signals in the Tibetan
        Plateau.}",
