GMES In-situ Coordination – GSIC

Goals:

  • To document the in-situ data required by the services

  • To identify gaps

  • To design an innovative and sustainable framework for open access to in-situ data

  • Monitoring networks currently provide robust integrated information and calibrate and validate the data from satellites
