PRODUCTS

Brief introduction

ECCO products are freely available through several applications. However, we ask that all users of these product use the following standard acknowledgment: "The state estimates were provided by the ECCO Consortium for Estimating the Circulation and Climate of the Ocean funded by the National Oceanographic Partnership Program (NOPP)."
-
- Data servers contain four groups of data:

Monthly, 10-day, daily or 12-hourly ocean model state, adjusted forcing fields and mixing coefficients -
Obsevational data sets as they enter the optimization -
Misfits between model output and available observations, as computed by the model cost/objective function -
Past published estimates are also kept on the data servers

ECCO products listed below are freely available through several types of servers (a direct link is provided below via each product's `Release Name' in the product table). We kindly ask users to refer to the citable identifier associated with the product they choose to use (provided below via the `Release identifier' links). The products are listed below in an order that reflects their time of publication (see `Release identifier'). The following products are currently being extended: ECCO-v4 (JPL/AER/MIT), SOSE (UCSD), ECCO2 (JPL), ECCO-JPL (JPL), and GECCO2 (UH).

ECCO products are primarily released in the form of monthly field time series. These fields are primarily distributed on their native model grid to allow for accurate transport and budget computations. However fields interpolated to a simple longitude latitude grid may also be provided, which can most easily be plugged into third party software. Some of the products further provide the associated obsevational inputs, which allow users to e.g. assess model-data misfits. Examples of these supplementary data sets are indicated by a '>' under the associated `Release identifier'.
