1) CLIVAR- A major component of the World Climate Research Programme This project was developed to try and understand changes in the climate as well striving to predict future climate. This project has a particular focus on the oceanic atmosphere and its influence and interaction on climate. An example of a more general objective of this project, in addition to many others, includes understanding climate variability and predictability based on the interactions between the tropics and the extratropics. Another more general objective of this project is trying to understand the interaction of monsoons with the Indian Ocean, El Niño-Southern Oscillation, and land surfaces processes. These are examples of areas of research that CLIVAR gets involved with. CLIVAR has developed projects that were first initiated by research programs such as the World Ocean Circulation Experiment(WOCE) and the Tropical Ocean Global Atmosphere project. a) One project initiated by WOCE, used for comparison by CLIVAR, was to document temperature and salinity data of hydrographic sections. CLIVAR is now repeating these observations in an attempt to understand the change that might be occurring. One specific initiative was the Argo project which is a project that intends to provide salinity profiles. Another specific objective of CLIVAR, working off of the research done by the Tropical Ocean Global Atmosphere is CLIVAR’s close study of the ENSO events. These events are quite devastating and being able to predict and forecast these events more efficiently is part of what CLIVAR is trying to do. b) Some of the observations needed in order to achieve their objectives entail salinity and temperature data, as mentioned earlier. Furthermore carbon inventories of the ocean might be very useful observations of the ocean as carbon is a very important resource and can be good predictor of certain phenomena. Other important observations include sea surface height, sea surface temperatures, and vector winds. Meteorological observations of course need to be made in understanding climate variability and its relation to oceanic processes or characteristics. Ocean color measurements are also inquired upon. These can

be useful in providing early indications of ENSO events. Observation on a global scale are vital c) In measuring salinity or temperature profiling floats are used. As discussed in lecture these so called ARGO floats drift with ocean currents and submerge themselves measuring temperature and salinity and then surfacing in order to communicate with satellites. The data collected from these observations have given significant information on the storage of heat and fresh water. Other types of technology include satellites which can cost billions of dollars. Satellites give data consisting of surface qualities of the
