How do we get the observations?
internet
GTS
EUMETCast
Acquisition (ECPDS)
Ingestion & processing
(SAPP)
Data storage
(DHS)
Analysis & forecast
(CCA/CCB)

9. 9
ECMWF Product Dissemination System - ECPDS
• Originally developed for
transmitting real-time data to
remote machines
• Adapted to acquire data in real-
time
• Highly configurable
• Browser-based user interface
• Multiple simultaneous transfers
• Monitored by 24/7 shift staff
• Analyst call-out when necessary

10. 10
Scalable Acquisition and Pre-Processing - SAPP
• Observations pushed to SAPP from
ECPDS
• Decode the various data formats
(e.g. BUFR, GRIB, HDF, NetCDF)
• Apply initial quality control
• Convert to a consolidated format
before delivering to data
assimilation
• Monitored by 24/7 shift staff
• Analyst call-out when necessary
