2004 – 2006 “Episode I”
Romanian National Meteorological Administration
SAFNWC/MSG products couldn’t be displayed by the forecaster’s visualization system (neX-REAP) since it couldn’t handle other color schemes than those built in…
The forecaster had to display the products on a separate computer/screen
No converter for BUFR/GRIB products to image
Expensive computer system (SUN Workstation)
Difficult to evaluate the products when one cannot overlay meteorological fields, etc.
However, forecasters quite enthusiast and willing to use the products
NWCSAF 2015 USERS’ WORKSHOP
“New” (but more powerful h/w)
– SUN Enterprise 3500 (2GB RAM, 4 CPU)
– SAFNWC/MSG v2008
– Operational (2008)
First Linux machine
– Fedora Core
– SAFNWC/MSG v2009
– Operational (2010)
EUMETCAST hot standby system
2007 - 2010 Linux – “A New Hope”

And finally Linux!
An easier installation of the NWCSAF/MSG
Cheaper hardware (Workstation/Desktop PC)
Separate production and development machines
NWCSAF/MSG accessible to more people
Backup machine now affordable
Free software! (compilers, OS)
And a lot of enthusiasm!
But… still not possible to visualize the products on the forecaster’s system (obviously not NWCSAF/MSG software’s fault)

SAFNWC/MSG virtualization
Vmware ESXi 3.5
Fujitsu-Siemens TX200 S4 (2x Intel Xeon, 16 GB RAM…)
VM operational
Benefits:– Shorter downtimes –> in case of malfunction, just fire up a clone of the most recent functioning VM– Easy to install new versions of the SAFNWC/MSG -> use a pre-configured copy of your favorite OS as a
VM– Handy for testing new configurations /experiment– Can run production and development VM’s on the same h/w– Easy backup/transfer
Drawbacks: VM proliferation -> rare, only if one easily get attached to objects

SAFNWC VM farm
NWCSAF 2015 USERS’ WORKSHOP
Product Visualization & Integration:– Still not possible to ingest the PGE’s in the nexREAP visualization system -> one
more display on the forecaster’s desk, thin appetite for new products and even thinner for validation/evaluation
– Hopes rise in 2014 with the announcement of a new forecaster visualization system for 2015 - 2016
– It has been decided however to give a try to the ADAGUC -> might not replace a full fledged visualization system but it could certainly come close; badly needed in order to help “reboot” forecasters interest in both evaluation/validation and operational use of NWCSAF products
2011 - 2014 “Attack of the Clones”
Romanian National Meteorological Administration
NWCSAF 2015 USERS’ WORKSHOP
The focus is foreseen to be less on the processing chains (the technology is quite mature) but more on the evaluation/validation/utilization/integration of the SAFNWC products
The evaluation/validation requires not only a proper visualization system but also toolboxes capable to easily create scenarios for automated validation using long product time series (short time series and case studies are useful but not enough) -> will become a “must” with MTG’s 5/2.5 min scan, 1(2) km resolution
2015 – onwards “The Force Awakens”
Romanian National Meteorological Administration
NWCSAF 2015 USERS’ WORKSHOP
More data (MTG: 1km/2km resolution, 16 channels) and more often (5/2.5 min scans) -> more products (old + new)
Higher demand for accurate/ real-time products
As a result, more CPU’s will be needed quite soon
However, if Moore’s law still holds, computing power should not be an issue
But what about Time? Will it be still possible for a human to use in nowcasting 2 (or 3?) dozens of new products coming every 2.5 minutes?
(Semi) automated nowcasting systems will certainly help, but complex visualization systems will still be needed in both operational meteorology and product evaluation/validation
What should we expect from the future?

NWCSAF 2015 USERS’ WORKSHOP
10 years of SAFNWC have been challenging in many ways but exciting and rewarding
The next 10 look even more interesting
There are many things we could have done better and faster
We have been learning a lot and teach others some
