This page provides details regarding the Water Temperature metadata Pilot Project (META-T PP) establishment, its goal, and membership. The Water Temperature metadata pilot project is aiming at providing an international standardization framework for collecting SST and water temperature profile instrumental metadata from a number of marine observational systems, including drifting and moored buoys, observing ships, sea level stations, sub-surface profiling floats, ocean reference stations, and ODAS. It is being developed under the umbrella of the Joint WMO-IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM).

Following previous discussions with the DBCP,the SOT, OCG, and the JCOMM Management Committee,the Water Temperature metadata Pilot Project (META-T PP) was establishedby JCOMM/OCG workshop, Reading, United Kingdom, 28-29 March 2006.

The goals of the workshop were:

  1. To consider user requirements, metadata relevant for the pilot project, and to draft the list of required metadata and categorization;
  2. to identify the metadata information that needs to be available in real-time;
  3. to identify centre(s) to host/serve metadata;
  4. to develop an action plan for advancing the pilot project.


At the same time the following issued were considered:

  1. minimizing the number of duplicate records;
  2. seeking agreed formats and practices, as several communities had been pursuing metadata development strategies;
  3. seeking to harmonize the ocean, met-ocean and atmospheric community practices as far as possible;
  4. reviewing metadata needs of the developing operational oceanography community.


The meeting reviewed all of the in situ ocean observing systems and data management counterparts delivering SST and temperature profile data. These include:

  • The Global Ocean Surface Underway Data Pilot Project (GOSUD),
  • The Global Temperature-Salinity Profile Program (GTSPP)
  • The Argo profiling float Pilot Project
  • The Data Buoy Cooperation Panel (DBCP) and its Actions Groups
  • The Ship Observations Team (SOT)
  • OceanSITES
  • The Ocean Data Acquisition Systems (ODAS)


The following user requirements have been considered:

  • Numerical Weather Prediction (NWP)
  • SST analysis and GODAE High Resolution SST Pilot Project (GHRSST)
  • Data assimilation and ocean field analysis
  • Ocean modelling
  • Ocean modelling validation
  • Climate forecast
  • Seasonal to decadal climate variability
  • Satellite calibration
  • Satellite validation
  • Operational activities (e.g. weather forecasters, disaster response)
  • Quality assurance activities serving above applications
  • Diagnostic by platform operators
