Oceanography TROPICAL OCEAN and GLOBAL ATMOSPHERE PROGRAMME TOGA Background A major component of the TOGA International Implementation Plan was the monitoring of the global atmosphere and the upper layers of the three tropical oceans during the ten-year period of 1985-1994. Existing meteorological and oceanographic observation systems were maintained and expanded by TOGA, while new networks were also installed in key locations. These observations, along with available historical data, have provided a description of the ocean- climate system and its variability from sub-seasonal to interannual scales. TOGA Tropical Subsurface Data Centers The TOGA Tropical Subsurface Data Centre in Brest, France operated within the framework of both the IOC's International Oceanographic Data and Information Exchange (IODE) system and the Joint IOC-WMO Integrated Global Ocean Ser- vices System (IGOSS). This Centre has been continued for the WOCE program as the Global Subsurface Data Centre. The Centre collects subsurface ocean observa- tions from the following sources: (1) tropical oceans observations from the IGOSS network; (2) additional vertical temperature profiles from XBT's and from drifting or moored buoys with thermistor chains, not sent over the GTS; (3) time series of temperature and salinity at fixed depth from moored thermistor chains; (4) sur- face temperature and salinity data and vertical profiles of temperature and salin- ity from CTD's, bottle casts, and WCTD's; and (5) other subsurface ocean mea- surements from process-oriented intensive oceanographic observation projects in the tropical oceans. Initially, data are collected from radio transmissions, with fully digitized and quality controlled observations added with time. The subsurface thermal data described above are analyzed, and the Centre assembles and disseminates qual- ity-controlled Level II-B data sets for the Global Oceans
