#### Description

This dataset contains 15-day forecasts of the atmospheric model variables
generated by the ECMWF Integrated Forecasting System (IFS) at 0.25 degree
resolution. We refer to these as Near-Realtime (NRT) because new products
are released twice a day after the release of the ECMWF realtime forecast
data, of which this is a subset. Data may be distributed and used
commercially with
[proper attribution](https://apps.ecmwf.int/datasets/licences/general/).

Products are available in Earth Engine starting with the implementation of
[Cycle 49r1](https://confluence.ecmwf.int/display/FCST/Implementation+of+IFS+Cycle+49r1)
on 2024/11/12; earlier products are not included. For general information
about how to use ECMWF NRT datasets, see their
[user documentation](https://confluence.ecmwf.int/display/DAC/ECMWF+open+data%3A+real-time+forecasts+from+IFS+and+AIFS).
