Multiscale Hydrologic Remote Sensing: Perspectives and Applications
MATSIRO model can reproduce the patterns (in terms of amplitude and timing) of
GRACE TWS variations remarkably well at both seasonal (Figure 20.7a) and inter20.7a) and inter.7a) and interannual (Figure 20.7b) time scales in most basins, although some month-to-month
discrepancies can be significant, for example, in Congo, Lena, Mississippi, and
Murray-Darling (Figure 20.7b).

FIGURE  20.7  (a) Comparison of 2002–2007 mean annual cycles of the total TWSA
between MATSIRO model simulations (black) and GRACE (red) for 12 selected river basins.
Shading (red) denotes the range of different GRACE datasets used. Red vertical bar denotes
the range of the interannual variability of monthly GRACE TWS variations.
