The Global Climate Observing System (GCOS) recognizes the Global Temperature and Salinity Profile Programme (GTSPP) as one of the international operational activities that provide essential, sub-surface climate variables of temperature and salinity profile data. GTSPP provides timely and complete data with documented quality flags and implements internationally agreed quality control and overall management of ocean data fully in accordance with the GCOS action plan


  • Provide timely access to the highest quality, highest resolution temperature and salinity profile data.
  • Implement data flow monitoring system for improving the capture and timeliness of real-time and delayed-mode data.
  • Improve and implement agreed and uniform quality control and duplicates management systems.
  • Facilitate the development and provision of a wide variety of useful data analyses, data and information, products, and data sets.
