    Hi Windy team/community.

    I came across this feature with ECMWF date ( others have mentioned it ).

    Could this be a future feature?

    Below are some examples of the Simulated satellite data via twitter users:
    https://twitter.com/search?q=ECMWF Simulated satellite data&src=typed_query

    The major highlights are:

    Global satellite images capturing detailed cloud and/or humidity features
    The new simulated satellite data product shows the high-resolution ECMWF forecasts as a weather satellite would see it (e.g. Meteosat-10). The new product includes latitudes greater than 60° north and south, extending the geostationary-type imagery over high-latitude regions.

    Nadir view for every model grid point
    The new simulated satellite data assume a nadir view (top-down) for every model grid point so the effect of looking slantwise through the atmosphere is neglected.

    Produced in post-processing within the IFS, with no mapping on satellite grid
    This is a technical advantage of the new simulated satellite data being now produced in the post-processing within the IFS and being part of the research tests for operational release to validate model developments which affect the temperature and moisture fields.

    Availability of the simulated satellite data in MARS
    The new simulated satellite data products are archived in MARS in GRIB edition 2 and are available at every post-processing step, out to 240 hours: 3 hourly from T+0 to T+144 and 6 hourly from T+150 to T+240.

    Availability of the simulated satellite data in ECMWF Catalogue and dissemination in the future
    The timeliness of delivery is optimal for dissemination. The addition of the new simulated satellite data products to the ECMWF Catalogue will be proposed. It will not be available to commercial customers / researchers until then.

    At present only Meteosat-10-like simulated satellite data are available. The central wavelength of the channels on other geostationary platforms is quite close to those selected to be produced, archived and disseminated based on the Meteosat-10-like data.

    Would be nice to get them but unfortunately a lot of data from ECMWF are not for free. I didn’t check simulated satellite data in particular but it is most probably the case. The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organisation supported by 34 states. ECMWF is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its Member States. This data is fully available to the national meteorological services in the Member States.
