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 0.4 degrees resolution in GRIB2 format unless stated otherwise. Since July 2023, the encoding of products in GRIB2 has changed to use CCSDS compression.
Important: higher resolution versions of the same products are available via the Product Requirements Catalogue and are subject to the ECMWF Standard Licence Agreement.

Tropical cyclone tracks - ensemble products
The tropical cyclone trajectories are computed independently for each ensemble member; a given tropical cyclone may dissipate at different times in different members so the number of members predicting a given tropical cyclone may vary through the forecast.
