Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-01-08T00:00:00.000+00:00
This collection contains the Ocean Surface Topography Mission (OSTM)/Jason-2 Auxiliary data files. These auxiliary data files are used to generate Level-2 products. They include both static tabular data files and dynamic files which change/grow over time. Auxiliary files are produced outside of OSTM but are used in the production of Level-2 products. Auxiliary data, which are produced by the European Center for Medium range Weather Forecasting (ECMWF), are restricted by ECMWF to the project team. Other data/products associated with OSTM/Jason-2 are also available, including Level-2 Geophysical Data Records (GDRs), ancillary data files used to generate Level-2 products, quality reports from the near real-time altimetry validation system (NRTAVS), orbit information of JASON-2 satellite and telemetry data.
