Characterization and Assessment of Land Signals in GRACE Follow-On Datasets
Abstract
The joint NASA/GFZ GRACE Follow-On mission was launched on May 22, 2018. The science data, including the Level-1 tracking and Level-2 gravity field models, were made available to the user community in Spring 2019. There is approximately one year gap between end of GRACE mission data and the start of GRACE-FO data. The gap may be as long as two years if the degraded GRACE data since late 2017 are removed from consideration. This paper, after a brief introduction to the status of the GRACE Follow-On mission, presents a characterization of land domain signal continuity across the data gap since the GRACE mission end. Since there may not be sufficient length of data record, any error quantification must be regarded as provisional. However, ancillary information (such as precipitation or other in situ data) offer insights into the quality of the hydrology information in the GRACE Follow-On datasets.
