Product description
These products are a subset of the full
Catalogue of ECMWF Real-time Products
and are based on the medium-range (
high-resolution and ensemble
) and
seasonal
forecast models.
The data are released
1
hour
after
the
real-time dissemination schedule
.
Products are produced at 0.25 degrees resolution in GRIB2 format unless stated otherwise. Since July 2023, the
encoding of products in GRIB2 has changed to use CCSDS compression
.
Products produced at 0.4 degrees under the 'beta' folder will be retired in May 2024. We advise all users to move to the 0.25 degree resolution data.
Important: higher resolution versions of the same products are available via the
Product Requirements Catalogue
and are subject to the ECMWF Standard Licence Agreement.
