Coordination Group for Meteorological Satellites - CGMS

CEOS SIT Technical Workshop, Darmstadt 16 Sep 2015


CGMS coordination with CEOS Virtual Constellations for Ocean

Mikael RattenborgCGMS secretariat



CGMS coordination in the Ocean context

• Overview– CGMS Satellite contributions to Ocean observations– CGMS Areas of Coordination– Relation to activities of CEOS Virtual Constellations– Ongoing CGMS actions on Ocean– CGMS-42, May 2014 focus on oceanography



CGMS contributions to Ocean observations

• Satellites now contribute to 14 out of 31 Ocean Observational Variables (Source: WMO)

• CGMS baseline GOS missions are flying sensors of high interest to the Ocean community– New instrumentation in basic SSO (Metop/ASCAT, NPP/VIIRS, FY-3/MERSI)– GEO capability for Ocean Colour (COMS-1/GOCI)

• CGMS members are increasingly involved in dedicated ocean missions– Operational altimetry system in MEO and SSO (Jason-2/3/CS, S-3)– Operational ocean colour in SSO (JPSS, S-3)– R&D missions in SSO (Oceansat-2, SMOS, SMAP, SAC-D, HY-2, GCOM, PACE)

CGMS coordination Areas• Coordination of observing systems and protection of assets

– Support to the definition and maintenance of observational user requirements– Gap analysis and contingency planning– Orbit optimization– Frequency coordination and protection– Direct readout standards– Data collection coordination– Coordination of regional retransmission services for LEO satellites

• Data dissemination, direct read out services and contribution to the WIS Products development– Global data exchange– Establishment of standards for distribution formats and discovery metadata standards– Coordination of regional re-dissemination– Coordination of dissemination mechanisms– Integration of satellite data in the WIS



CGMS Coordination areas• Enhance the quality of satellite-derived data and Products

– Best scientific practice for products definition and validation– Establishment of a fully consistent operational system for satellite data calibration– Define standards for product formats and service metadata

• Outreach and training activities– Coordinated global training activities to foster maximum use of satellite data– Socio-economic benefits assessment for satellite data– Support to regional data users conferences



CGMS High-level Priorities referencing Ocean directly

1.1.1 Coordinate the implementation of the CGMS baseline missions (updated nominal locations/orbits, operators), including optimisation of the distribution of Low Earth Orbit (LEO) sun-synchronous orbits to ensure efficient temporal sampling of the atmosphere and of the oceans

1.2.2 Assess Data Collection Platform (DCP) and Argos Data Collection System (A-DCS) status and evolutions including International channels, taking into account requirements of Tsunami alert systems and ocean observations (e.g. buoys)

2.5 Investigate the feasibility of introducing a coordinated dissemination service for information in support of the Ocean User Community



CEOS Virtual Constellations and CGMS• Coordination of observing systems and protection of assets

– Observational gap analysis is a focus area of all CEOS VCs– For ocean sensors flying on baseline GOS mission coordination efforts have

however to be coordinated with CGMS – Conclusion: Concrete action on orbit coordination and contingency planning

should be considered by CGMS, in particular for the ocean missions hosted on operational meteorological satellites

• Data dissemination, direct read out services and contribution to the WIS Products development– All VCs express needs for improved Data distribution and global data exchange– Resulting actions on near real-time access and dissemination are however

generally not addressed in CEOS context– Conclusion: There is clear need for CGMS actions in the areas of near-real-time

dissemination, including the integration of ocean-related satellite data and products in the WMO Information System (WIS) .



CEOS Virtual Constellations and CGMS• Enhance the quality of satellite-derived data and Products

– Focus area of all VCs, in particular the development and establishment of Ocean-relevant CDRs

– Conclusion: Area covered extensively by CEOS VCs, no need for specific CGMS actions in this area

• Outreach and training activities– All VCs have a focus on outreach activities.– The OSVW-VC initiated the series of marine forecasters courses, which has been

fully coordinated with CGMS training efforts.– Regarding outreach activities on socio-economic benefits for ocean, both CEOS

and CGMS are addressing this from their different perspectives– Conclusion: No need for specific coordination actions from CGMS



Ocean Issues currently considered in CGMS context

– Contingency planning for scatterometry missions following Oceansat-2 failure– Ensure NRT products availability from ISRO Scatsat mission– Ensure NRT products availability from NSOA HY-2 (also altimetry)

– Contingency planning for future GEO coverage over the Indian Ocean– Including Data Collection Service for in-situ ocean observations

– Advance operational implementation of ocean community data formats for NRT products produced from CGMS satellites– GRHSST for SST and netCDF4/CF for Ocean Colour

– Advance NRT dissemination of Ocean observations– Enhance dialogue with JCOMM to identify operational data needs

– Integration of ocean observations in WMO Information System (WIS) and WMO Integrated Global Observing System (WIGOS) – Definition of WIS and WIGOS metadata for ocean observations– Strengthen usage of space-based ocean data by WMO members

– Ocean Observations in baseline for Global Observing System– Space-based GOS revision planned in response to emerging new WMO WIGOS vision– Better consideration of Ocean colour in new baseline– SST 2025 vision



CGMS-42 May 2014

– Special focus on Ocean-related issues– Well-received presentations by CEOS Virtual Constellations

• Ocean Colour Radiometry Virtual Constellation (OCR-VC) status by Stewart Bernard, Chair of IOCCG

• SST constellation status by Gary Corlett, GHRSST Coordinator

– CGMS-42 Plenary session on Oceanography decided to:• Encourage the CEOS Virtual Constellations to submit papers to CGMS on relevant

operational matters with appropriate recommendations to CGMS.• CGMS secretariat to ensure that Ocean WPs are considered in all appropriate CGMS

WGs.• Strengthen the link to JCOMM, in particular the Cross cutting Task team on Satellite

Data Requirements• Continue the dialogue with GHRSST and IOCCG • Include Ocean-related matters explicitly on agendas of CGMS WGs.• In general encourage members to submit Ocean-related working papers for

consideration by CGMS




Thank you for your attention!
