RARS Network Status
• RARS currently provides retransmission of ATOVS L1c,
from 42 stations covering 80% of the globe, within 30 min
• 3 components:
– EARS (18 stations)
– Asia-Pacific (16 stations)
– Brazil/Argentina (8 stations)

What is RARS ?
• A network of Direct Readout stations sharing their data
in near real time …
• … following a set of procedures and best practices to
ensure interoperability, global availability and timeliness
of RARS products
• Key requirements:
– Use current AAPP and deliver L1c in BUFR
– Send over the GTS (and possibly other means) within 30 min
– Identifyers, Bulletin headings and WMO filename convention
• New codes and headings defined for IASI, CrIS, ATMS

Convergence between RARS and DBRTN (1)
NOAA/DBRTN and WMO/RARS are willing to share their data
DBRTN data would be sent to GTS via EUMETSAT and DWD
 Issue 1:Check NCEP-RARS compatibility of BUFR formats
Action: NOAA to review what is needed in BUFR format for CrIS, ATMS
and IASI and determine if they could use AAPP BUFR (i.e. RARS format)
instead of NCEP BUFR (Mitch Goldberg)
Action: NOAA to send samples of NCEP BUFR data to Nigel Atkinson
(Liam Gumley)
 Issue 2: Acceptable data rates for the GTS
Action: WMO will inform the group on the data rates supported by the
various links of the GTS (Jérôme Lafeuille)

Convergence between RARS and DBRTN (2)
WM OMM
 Issue 3: Ensure interoperability of RARS and DBRTN
• Action: SSEC, NOAA, EUMETSAT, WMO should coordinate
on data formats, software versions, and latency
requirements and come up with a plan to provide the DBRTN
products for inclusion in RARS .

ITSC-19, RARS Technical Sub-group
WM OMM
Draft WMO Guide on (D)RARS
• Direct Readout And Re-distribution System for LEO satellite data
• Addressing standard/recommended practices for
(D)RARS operators and users including:
– Processing software
– Product format
– Product distribution
– Service requirements
(availability, timeliness, quality control)
– User information
– Maintenance and Operations
– Procedure for station inclusion/removal

Convergence between RARS and DBRTN (3)
WM OMM
 Action: The draft Guide to RARS which defines the RARS
procedures, software, formats, data exchange convention,
service requirements, etc. should be finalized, published,
and shared widely with potential data providers (Jérôme
Lafeuille)

ITSC-19, RARS Technical Sub-group
Keeping RARS on track : governance
WM OMM
• RARS matters are addressed at ITSC, at CGMS-WGI, and at
NAEDEX-APSDEU
• Transition to advanced sounders and convergence with DBRTN
require special attention
 Action: There is a need for reactivating the RARS
Implementation Group within WMO with a broader scope to
include NOAA DBRTN (Jérôme Lafeuille)

Progress on RARS since ITSC-18
• Additional stations providing NOAA/ATOVS RARS products
– New-Delhi, Chennai (IMD) in test mode
– Tahiti (Meteo-France) to become operational within a few days
– Easter Island planned through agreement between CLS-Argos and Chile
• A number of stations (24 out of 42) providing METOP/ATOVS
• Hyperspectral IR sounder products
– EUMETSAT provides IASI and CrIS products on a pilot basis
– Codes and identifiers proposed for these new products
– Estimation of data rates (requested by APSDEU/NAEDEX)
• CGMS-41 was informed on the NOAA project of Real-Time
Network for Low-Latency Infrared and Microwave Sounder Data
– Recommended convergence with RARS
