The PO.DAAC is pleased to announce the public release of ECCO Version 4, Release 4b (V4r4b), an errata for the ECCO Version 4 revision 4 (V4r4) ocean and sea-ice state estimate. An issue has been identified and corrected with atmospheric pressure forcing used in V4r4. Main effects of the error are on sub-monthly time scales, for which a dynamical response to atmospheric pressure is expected. As a result, V4r4b only includes updated sea level and bottom pressure fields that are most measurably impacted by the error. See the errata document for details and corrected fields. Estimating the Circulation and Climate of the Ocean (ECCO) ocean and sea-ice state estimates are dynamically and kinematically-consistent reconstructions of the three-dimensional, time-evolving ocean, sea-ice, and surface atmospheric states (ECCO Consortium, 2021). More information regarding the ECCO project is available from PO.DAAC’s mission webpage.
