Thermal Infrared Remote Sensing and Sea Surface Temperature of Marine and Coastal Waters Around Africa

Owing to satellite-derived Thermal Infrared (TIR) data, it is possible to derive large basin scale view of Sea Surface Temperature (SST) around the African continent over the last 2 or 3 decades. This may form the baseline against which future changes can be measured. Measurements of SST also serve as an entry point to characterize the water dynamics along the African coast and to understand where and when changes have taken place, such that possible short- to medium term scenarios can be developed and used as management tools for precautionary measures. Significant advances in TIR technology have been achieved to build the necessary confidence in satellite-based SST measurements for research, as well as for operational and commercial purposes. An effective dissemination of these EO value added products to African institutions and policy-makers is a key condition for long-term sustainability of coastal and marine resources. The chapter presents a variety of applications using TIR images and SST data that have contributed to develop the necessary knowledge and competences that are critical for the implementation of conservation and management strategies at continental, regional and national scales.
