Atmospheric

Services

  • Harmonised coordination of Atmosphere, Land and Ocean integrated projects of the GMES backbone (project lifetime: 1/2/2004 – 1/1/2007)

  • GMES Fast-Track Pilot Services to be operational from 2008

    • Marine Services (IP MERSEA follow-up)

    • Land Monitoring (IP GEOLAND-Europe follow-up)

    • Emergency Response (IP RISK-PREVIEW follow-up)

  • Proposed GEMS Fast-Track Pilot Services to be operational from 2009 onwards

    • Atmospheric Services (IP GEMS follow-up)

    • Global Land Monitoring (IP GEOLAND-Global follow-up)

    • Security

  • HALO aims at formulating agreed recommendations to GAC and IPs

  • Scientific thematic analysis of links:

    • Direct product exchange

    • Unaccomplished data demands

    • Common data

  • Coordinated solutions to infra-structure in operational mode

    • Candidate solutions by Alcatel and Astrium

Progress of the Candidate Solution Definition

2004 Reports:

“ECMWF’s data and products for GMES”

“geoland data and products for GMES”

“MERSEA data and products for GMES”

“GEMS data and products for GMES”

2005 Reports:

“Interacting parts of GEMS, MERSEA and geoland: Data, products and infrastructure”

“HALO Guideline”

2005/2006 Draft Report:

“Infrastructure candidate solutions overview”

What data flows are expected?

draft discussed at 2nd Workshop and updated afterward


Chief Objectives of this Meeting

  • Project-internal Agreement on

    • which candidate solutions shall be assessed,

    • advantages and disadvantages of each,

    • which one HALO shall recommend.

Data Flow Characterisation


Data Categories used in the HALO Reports

  • categories of exchange

    • internal: within one IP

    • interacting: between two IPs

    • external: between an IP and a third party

  • observation categories

    • in-situ

    • satellite-based

  • delivery mode

    • real-time / near-real time

    • regular

    • on-demand / offline


MERSEA data flow: Interacting, External, Internal


geoland Data Flow: Interacting, Internal


geoland Data Flow: External


GEMS Data Flow: Interacting


GEMS Data Flow: External, Internal

  • Is there a role for WIN and ORCHESTRA?


2nd HALO Workshop Infrastructure Conclusions(December 2005)


Selected Conclusions on Infrastructure Candidate Solutions

  • need description of two alternative technical solution candidates

    • one using the existing meteorological network, ie GTS

    • another EUMETCast

    • Does WIS encompass both GTS and EUMETCast?

  • compare the two solutions:

    • commonalities and differences

    • advantages and limitations

  • Data policy implications of the two solution candidates shall be pointed out.

  • an additional HALO meeting to decide on a solution recommendation

  • separate the discussions of solutions for the operational real-time data flow and for the data access for time-lagged products like reanalyses.
