Global Temperature and Salinity Profile Programme (GTSPP)

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
