Error Assessment of GRACE and GRACE Follow?On Mass Change

Signal and error in mass change inferences from GRACE: the case of Antarctica

Accuracy of GRACE mass estimates

[1] The GRACE satellite mission is mapping the Earth’s gravity field at monthly intervals. The solutions can be used to determine monthly changes in the distribution of water on land and in the ocean. Most GRACE studies to-date have focussed on producing maps of mass variability, with little discussion of the errors in those maps. Error estimates, though, are necessary if GRACE is to be used as...

Greenland mass balance from GRACE

[1] We use 22 monthly GRACE (Gravity Recovery and Climate Experiment) gravity fields to estimate the linear trend in Greenland ice mass during 2002–2004. We recover a decrease in total ice mass of 82 ± 28 km of ice per year, consistent with estimates from other techniques. Our uncertainty estimate is dominated by the effects of GRACE measurement errors and errors in our post glacial rebound (PG...

Grace

whence she had come nor whither she was bound, for she had no record of any kind with her. When she was questioned her vocabulary seemed to consist solely of head shakings and a few utterly unintelligible syllables. It is not recorded how Grace happened to be thrust into a second grade that first day. But it was the second grade teacher who began to complain, a few days later, of "that little n...

Needs Assessment for Grace Adult

Interpersonal skills have always been a foundation for any human civilization. Current research, as well as practical data illustrates that there is no exception for the need for interpersonal skills in today' s business .environment. Current research discusses the growing need for such skills in today' s business environment, specifically management. Practical observation is uncovering the imp...
