WMO Integrated Global Observing System (WIGOS)
4th WCRP Observations and Assimilation Panel (WOAP) Meeting
Barbara J. Ryan
Director, WMO Space Programme
29 March 201029 March 2010HamburgHamburg
Overview
• Recognition of the Need
• Congressional Guidance
• Principal Documents
• WIGOS Projects
Recognition of the Need
• Different and diverse WMO observing systems to meet weather, water and climate requirements
• Wanted a more holistic approach
• Better leverage limited resources
WMO Congress and Executive Council
• Towards enhanced integration among the WMO observing systems – GOS, GAW, WHyCOS
• Intended to be a comprehensive, coordinated system for observing systems based on the requirements of all WMO Programmes
• Monitor development and implementation of WIGOS (and WIS) through a “RRR” process
A Diverse System
Space-based Component of WMO’s Global Observing System (GOS)
Rolling Review of Requirements
– Database of user requirements per application area
– Database of observing capabilities (space + surface)
– Critical Review of how requirements are satisfied by
current/planned capabilities for each application area
User Requirements
• 25 Programmes• 120 geophysical parameters • Atmospheric, oceanic, terrestrial domains• 632 requirements recorded (parameter x domain x application)
• Each requirement: 5 criteria x 3 values (ideal/ goal/ threshold) and 3 attributes (confidence, date, authority)
11376 fields recorded

WIGOS Framework
• To facilitate standardization and interoperability
• To ensure: availability of, and real and near-realtime
access to good quality data/products and associated metadata
data quality standards are documented, met and sustained
Standardization – 3 Key Areas
• Measurements and observations -- homogeneity, interoperability, compatibility of all
observations
• Data exchange, discovery, access and retrieval (DAR) -- standardized set of data representation and exchange requirements for all WMO Programmes & DAR services
• End-product quality management -- QMS
QMF Standards

WIGOS Pilot Projects
Designed to:
• Test WIGOS concepts
• Identify problem areas
• Help in elaborating Implementation Plan
WIGOS Pilot Projects
I: Improvement of Dissemination of Ozone and Aerosol observations through WIS (IDOA)
II: Hydrological Applications Runoff Network (HARON)
III: Integration of AMDAR into WIGOS
IV: Elaboration of the underpinning/crosscutting role and responsibilities of the Instruments and Methods of Observation Programme
V: Integration of Marine Meteorological and other appropriate Oceanographic Observations into WIGOS
Demonstration Projects at NMHSs
• Test how to implement WIGOS with WIS components running at the required levels of performance
• Feedback and lessons learned for WIGOS/WIS concept implementation
• Include national observing networks that provide data and information for basic operations of NMHSs
WIGOS Demonstration Projects
RA I: Kenya, Morocco and Namibia RA II: Republic of KoreaRA III: Brazil RA IV: USARA V: AustraliaRA VI: the Russian Federation
