Examples

CAMS atmospheric composition forecast experiment set up to explore data information content in the scope of a ESoWC project. The data is encoded as IEEE single-precision (32-bit floats) circumventing any other lossy compression. This is in contrast to the default 24-bit linear packing used for CAMS in the ECMWF data archive and on the Copernicus Atmosphere Data Store.

Coupled subsesaonal reforecasts (ENS-C) consisting of 10 perturbed members, each integrated for 46-days, starting on the first of each month between 2006 and 2023 for a total of 216 start dates. The atmospheric model is configured to use the cubic octahedral reduced Gaussian grid with 137 vertical levels and a horizontal resolution of Tco319. The atmosphere is coupled hourly to an eddy-permitting NEMO4-SI3 configuration, which uses 75 vertical levels in the ocean and the eORCA025 grid.
