EARS-ATOVS


EARS-ATOVS (1/2)

Design:• Decentralised processing and data compression into bzip2 to reduce

data volume.• Processor: AAPP (v7.3) as delivered by NWP SAF.• Distribution via EUMETCast Ku-Band and GTS.• All satellites: NOAA 15, 16, 18, 19 and Metop-A.• Number of stations: 15.

Products, formats:• One set of products per pass, including:

– Level 1a per ATOVS instrument, data in AAPP format, bzip2 compressed.

– Level 1c per ATOVS instrument, data on original instrument grid, BUFR format.

– AVHRR derived cloud mask on HIRS instrument grid (Level 1d), BUFR format.

• Operational monitoring by NWP SAF

Timeliness:• < 30 minutes for Athens, Gander, Gilmore, Kangerlussuaq, Lannion,

Maspalomas, Saint-Denis, Svalbard, Wallops, Moscow, Muscat, Miami, Edmonton.

• < 45 minutes for Monterey.• ~ 60 minutes for Ewa Beach.


EARS-ATOVS (2/2)

Number of Users on EUMETCast:• > 1000 registered Users.

Number of products per day:• ~ 2000 products, corresponding to 625 MB.

System evolutions in the near future:• Metop-B.• New stations.

Fast Dump Extraction System – FDES (1/2)

Metop-A HRPT operated on Southbound orbits over Europe and also partly on Northbound orbits.

The FDES service provides data from Northbound orbits based on a extract of the Global Dump data.

Timeliness 10 Minutes



• Both Metop-A HRPT and FDES Data available via EUMETCast and GTS


Fast Dump Extraction System – FDES (2/2)

FDES provides full Northern Hemisphere coverage for Metop-A Ascending passes for EARS-ATOVS, -ASCAT, -AVHRR, -IASI and -NWC.

EARS-ASCAT Daily Coverage


Ongoing developments

• Start of Metop HRPT operations at Kangerlussuaq, Svalbard, Wallops, Gilmore, Gander and Edmonton; FDES still used for Metop-A;

• Metop-B integration in EARS-ATOVS, EARS-AVHRR, EARS-ASCAT, EARS-IASI and EARS-NWC;

• Finalisation of the European station upgrade to X-Band;• Upgrade of the PPN servers and EUMETSAT servers to IBM

Linux;• Finalisation of the EARS-IASI and EARS-NWC developments;• Consolidate pass scheduling with multiple stations at

individual sites;• Inclusion of Resolute Bay, Novosibirsk and Khabarovsk into

EARS-ATOVS;• Ongoing upgrade of the EARS IP-VPN network to

accommodate the new NPP data flows.Slide: 18


Product Processing Node

PPN model is IBM x3690 X5. Linux based. Machines are deployed to all sites: prime and spare.

Intel Xeon - 20-cores8 disks in RAID
