SESAR (Single European Sky ATM Research) Deployment Projects

The SESAR Harmonised Turbulence and 3D Radar services build a common aviation weather reference wherever you are in Europe, so that more optimal flight planning decisions can be made to avoid disruption and delays for passengers and cargo.

Through a better understanding of where potentially hazardous weather conditions will occur en-route, airlines and Air Traffic Control can reduce the number of reactive diversions which cause additional fuel burn resulting in increased CO2 emissions and costs. 

The Met Office has worked with partners across Europe on three SESAR Deployment projects which provide aviation stakeholders with new tools to make dynamic decisions based on the prevailing weather conditions for all stages of a flight. 

Discover the data via the SWIM registry

You can access the data from two of the SESAR Deployment Projects via the Met Office.  Discover more about these new services through the SWIM registry. 

SESAR Deployment Project: European Weather Radar Composite of Convection Information Service (IP067)

The 3D RADAR service is available in a choice of two formats, HDF5 or GRIB2.

Please read the SWIM Registry Service Description for full details about this service, including sign-up instructions, 3D RADAR Service (HDF5) or 3D Radar Service (GRIB2).

The Met Office has delivered a 3D mosaic of weather radar over Europe which preserves height information to give a greater understanding of the development and intensity of convective storms. Two resolutions (and a choice of formats) are available: one covering UK-Ireland FAB and FABEC, the other covering a wider European domain (in lower resolution). 

The input radar data of this service has been provided via OPERA, the Radar Programme of EUMETNET, and has been processed and made available by the Met Office and Météo-France. 

SESAR Deployment Project: European Harmonised Forecasts of Adverse Weather (Icing, Turbulence, Convection and Winter Weather) (IP068)

Please read the SWIM Registry Service Description, SESAR Pan-European Harmonised Turbulence Service, for full details about these services, including sign-up instructions. 

The Harmonised Forecasts of Adverse Weather services take the individual forecasts from participating National Met Services and blends them to produce a common reference for aviation weather hazards across Europe. 

The Met Office has delivered a blend of turbulence data from the Met Office, Météo-France and Deutscher Wetterdienst (DWD) to produce a harmonised, pan-European view of forecast turbulence, with the additional option of a polygon features service marking regions of low, moderate and severe intensity levels.  

The Met Office also contributes to the harmonised forecasts of icing and convection over Europe available from our partners.

Who can access the Harmonised Turbulence and 3D RADAR services? 

The Harmonised Turbulence and 3D RADAR services are primarily intended for use by a number of aeronautical organisations for aviation purposes – please check the following list to check your organisation’s eligibility to use these services:
•    Airlines
•    Air Traffic Control
