MTG Services

With Meteosat Third Generation (MTG) the user community can look forward to continued visible observations from geostationary orbit, as well as the use of observations from infrared and ultraviolet/visible sounding instruments.

The benefits of MTG

  • Improved imagery at 10-minute full disc repeat cycles.
  • Infrared and ultraviolet & visible sounding data crucial for NWP assimilation and the future derivation of quantitative products.

Such improvements will address user requirements on spatial resolution; repeat cycle and signal-to -noise ratio, and are a prerequisite to conduct soundings from geostationary orbit.

Utilisation of the full suite of MTG instruments in an integrated approach, provides the new ways to follow the weather systems ‘from the cradle to the grave’.

The satellites' three axes stabilised platforms will host instruments with additional channels, with better spatial, temporal and radiometric resolution than the Meteosat Second Generation (MSG) satellites.

Product Processing

The EUMETSAT Ground Segment is being upgraded to accommodate the future processing requirements of MTG imager and sounder data. The Central Application Facility will also be upgraded to accommodate the central processing of MTG data.

The Satellite Application Facility (SAF) enhancements are also considered in the planning for the next steps of the SAF Continuous Development and Operations Phases (CDOP).

Data Delivery

NetCDF-4 is the baseline format for the FCI, LI and IRS instrument level 1 dataset generation. NetCDF-4 offers a number of advantageous features, including:

  • Ability to cope with large dataset sizes — ~7 Gbytes for Full Disc archived dataset for MTG compared to the current ~220 Mbytes.
  • Datasets are self describing.
  • Groups allow potential for easier subsetting.

BUFR, GRIB and other formats will be used where there is already a product delivered in that particular format.
