- Nadir view for every model grid point
The new simulated satellite data assume a nadir view for every model grid point so the effect of looking slantwise through the atmosphere is neglected. Consequently the atmosphere appears less opaque than with the old simulated images. - 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. This is an enhancement with respect to the previous product generated only in the early delivery cycles of the operational suite as they can be now used routinely in ECMWF Research Department experiments 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. This is an enhancement with respect to the previous satellite image product available in GRIB edition 1, out to T+120 only. - 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 added to the list of products that can be requested in disseminationavailable 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.
