The raw instrument data will be broadcast in real time by the satellites, to be received by suitably equipped user stations during the relevant passes. The meteorological-satellite X-band (7750-7900 MHz) is being considered for this service; moving to this band from the L-band currently used by Metop is necessary due to the larger amount of data to be transmitted. A continuation of the broadcasting in L-band may be implemented for a subset of the instrument data.
Global Data Service
The instrument data will be provided to the users in near real time, after their acquisition and processing by the ground segment to obtain geometrically consistent and calibrated radiance values, and a number of geophysical variables with global coverage. The time between observation by the instrument and delivery of the data to the users will range between 60 and 120 minutes, mainly depending on geographical location of the observations. The delivery mechanisms will be based on an evolution of the current EUMETSAT systems such as EUMETCast.
Regional Data Service
The timeliness of selected data from observations over Europe and the North Atlantic will be shortened to 30 minutes. For the distribution of the data to the users the same mechanism of the Global Data Service will be used.
Archive and Retrieval
The instrument data will be archived and be available for retrieval via the internet together with the data of all other EUMETSAT satellite systems.
