The 2024 GRACE-FO Science Team Meeting will take place Oct 8-10, 2024 at GFZ (Potsdam, Germany). We are planning for an in-person meeting, with a remote participation option (i.e., hydbrid meeting).

Please visit the meeting website for up-to-date information.

The updated RL06.1 Level-2 gravity fields improve the low-degree harmonics time series, and the corresponding Level-3 mass change fields (e.g., over Antarctica).

The GRACE-FO Science Data System team at JPL, GFZ and CSR has reprocessed the Level-1 ACC data and released a new Level-1B ACX data product. ACX is an updated hybrid ACC-transplant that uses observations from both the GF1 and GF2 accelerometers. With this, we can better account for differential non-gravitational forces between GF1 and GF2 – which in turn results in the improved monthly gravity fields.

The ACX-L1B product requires significantly more validation and verification during its production. While the SDS team will strive to adhere to the weekly Level-1 delivery schedule, we anticipate that at least initially, ACX-L1B will be delivered in a delayed mode, together with the corresponding monthly L2/L3 data deliveries (current latency: ~40 days).

The GRACE-FO Science Data System team has published a mission baseline reference paper, characterizing the instrument, flight system and science data performance over the first two years since launch:
