GRACE-FO: new data release RL06.3 now available
The updated RL06.3 Level-2 gravity fields improve the low-degree harmonics time series, and the corresponding Level-3 mass change fields. The GRACE-FO Science Data System team at JPL, GFZ and CS... moreThe updated RL06.3 Level-2 gravity fields improve the low-degree harmonics time series, and the corresponding Level-3 mass change fields.
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 ACX2 data product. ACX2 is an imporved 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 ACX2-L1B product requires significantly more validation and verification during its production. These data will be delivered in a delayed mode, together with the corresponding monthly L2/L3 data deliveries (current latency: ~40-60 days).

The international GRACE-FO Science Team discussed the status of the mission, novel science and applications results and plans for the extended mission period. Over 100 participants joined in person, 40 participants online (many early-career scientists!)Overall, >65 papers were presented and discussed, and can be accessed through the meeting website.

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).
