ABSTRACT
Sometimes one may have the impression that in recent years interest in the problem of satellite data calibration, in tuning algorithms of data processing using in situ data, has decreased. Problems of collecting subsatellite 'sea-truth' data in the mid1980s drew the attention of many experts and organisations involved in remote sensing of the Earth in general, and satellite oceanography in particular. The keen interest in this matter could be traced in the large number of scientific publications in the world science literature. This 'information explosion' could be explained from the viewpoint of a general assessment of the state-of-the-art of Earth observation from space at that period: as mentioned earlier, on the one hand, the amount of satellite data was increasing and, on the other, a lot of methodological and technological problems of data processing and information presentation and use have not yet been solved.
