Spurious barometric pressure acceleration in Antarctica and propagation into GRACE Antarctic mass change estimates
Geophysical Journal International(2016)
摘要
Apparent acceleration in Gravity Recovery and Climate Experiment (GRACE) Antarctic ice mass time-series may reflect both ice discharge and surface mass balance contributions. However, a recent study suggests there is also contamination from errors in atmospheric pressure de-aliasing fields [European Center for Medium-Range Weather Forecast (ECMWF) operational products] used during GRACE data proce...
