• Nadir view for every model grid point
  The new simulated satellite images 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 and so lower lying clouds and other features are better presented.
  
  
• Produced in post-processing within the IFS, with no mapping on satellite grid
  This is a technical advantage of the new simulated satellite images 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 images in MARS
  The new images product 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+48,  6 hourly from T+54 to T+120 and  then 12 hourly from T+132 to T+240. This is an enhancement with respect to the previous  satellite image product available in GRIB edition 1, out to T+120.
  
  
• Availability of the simulated satellite images in ECMWF Catalogue and dissemination
  The timeliness of delivery is optimal for dissemination. The new simulated images will be added to the list of products that can be requested in dissemination.
