CEOS has three primary objectives:

1.To optimize the benefits of spaceborne Earth observation through cooperation of its Members in mission planning and in the development of compatible data products, formats, services, applications and policies;

2.To aid both its Members and the international user community by inter alia, serving as the focal point for international coordination of space-related Earth observation activities, including those related to global change;

3.To exchange policy and technical information to encourage complementarity and compatibility among spaceborne Earth observation systems currently in service or development, and the data received from them; issues of common interest across the spectrum of Earth observation satellite missions will be addressed.

THE STRATEGIC IMPLEMENTATION TEAM (SIT)

The CEOS Strategic Implementation Team (SIT) was created in 1996 to advance the involvement of CEOS in the development of the Integrated Global Observing Strategy (IGOS).

The SIT comprises CEOS Member Principals with the authority to commit agency support to initiatives as they unfold and is chaired by JAXA.

The SIT’s purpose is to define, characterize, and develop the vision for CEOS’s participation in IGOS, to define and coordinate the space component of IGOS, and to address, with the relevant IGOS Partners, the interface between the space component and the in situ component.

Integrated Global Observing Strategy

IGOS is a structure that helps determine observation gaps and identify the resources to fill observation needs;

IGOS provides understanding of current system capabilities and limitations - thereby helping to reduce unnecessary duplication of observations.

IGOS is intended to cover all forms of data collection concerning the physical, chemical, biological and human environment including the associated impacts.

IGOS provides opportunities for capacity building and assisting countries to obtain maximum benefit from the total set of observations.

   Knowledge Challenges1

 Resolution

Challenges1

 Continuity

Challenges1

  Cross-cutting

   improve calibration and validation of satellite data   pixel “contamination”   need adaptive sampling   standardize and QA/QC in situ observations     address power/telemetry/bio-fouling issues for in situ assets

   require improved temporal and spatial resolution from satellite sensors   need to expand coverage of in situ measurements

 

   need to facilitate the transition from research to operational satellites   need to maintain and replace in situ assets

 

  GeophysicalObservations

   blending SST measurements    measuring salinity remotely   improve SSH measurements   develop SAR algorithms and assess other measurements   measure currents from space   assimilate HF radar data and derive user-driven products

   extracting higher-resolution info from satellite wind sensors   add additional Doppler weather radar & HF radar sites

 

   maintain and expand stream gauge and tide gauge networks   maintain microwave RS capabilities for ice   facilitate transition of HF radar from research to operational mode

 Biological &BiogeochemicalObservations

   need hyperspectral ocean color   improve bio-optical algorithms   merged chlorophyll products    relate ocean color/SAR data to ecological parameters    discriminate taxonomic groups   improve aerosol chacterizations   identify better surrogates for labor intensive biomass surveys

   need observations of ocean color from geostationary orbit to temporal resolution    more measurements of nutrients needed   need accurate/rapid assays for pollutants

   maintain global multi-spectral ocean color observations for context and climate data records
