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).
