Remote sensing has become an essential tool in oceanography. The development of new sensors and algorithms has extended the application of ocean remote sensing to new research domains, and new data analysis techniques are allowing to improve the quality of the data sets used for oceanographic and climatic research. Variables like sea surface temperature or those derived from the ocean colour have already shown their relevance to climate change studies. The use of satellite-derived salinity, as a fairly new data set, is an exciting opportunity to improve our knowledge of the ocean dynamics and interaction with the atmosphere.

There are also many open research questions that need to be addressed, or that are being actively addressed by the scientific community, and that are of particular interest for the 2012 Liège Colloquium: International efforts are aimed to quantify and correct biases between different sensors, which is needed for assessing long-term trends and their effect on the climate. The development and improvement of techniques to merge data from different platforms and create homogeneous time series is also needed. New challenges appear with the regionalisation of algorithms and their adaptation to coastal and closed domains. Uncertainty estimation needs to be assessed, and the retrieval algorithms need to be improved as we increase our knowledge of the ocean. The use of geostationary satellites allows for an estimation of the processes occurring at sub-diurnal scales, and specific algorithms for this type of platform may provide new opportunities, particularly for ocean colour.

The 2012 Liège Colloquium will be devoted to the latests developments in the research fields of salinity, temperature and ocean colour remote sensing. Open scientific questions and new research directions are of particular interest.
