RESUMO:

The Gravity Recovery and Climate Experiment (GRACE) has been monitoring the terrestrial water
storage anomalies (TWSA) since April 2002. The Space Research Center (CSR), Jet Propulsion
Laboratory (JPL), and Goddard Space Flights (GSFC) are operationally providing individual monthly
solutions based on the mass concentration (mascon) solution as the radial basis function. The
inverted TWSA maps (or regional average values) from these centers are being used in many
applications; however, as terrestrial data are unavailable, the uncertainties and their confidence
intervals are unknown. Consequently, this work aims to evaluate the quality of each TWSA solution
from the three processing centers using a generalized formulation of the three-cornered hat
method (TCH) and estimate the respective confidence intervals for the uncertainties. Overall, the
TCH results for the study period from April 2002 to June 2017 indicate that the uncertainties of
CSR, JPL, and GSFC are 34.4, 47.4, and 38.7 mm, respectively. On a basin scale, the overall good
overall performance of the CSR is observed. The THC-based results agree with an ensemble
solution from the three solutions.
