7 Conclusion 
This work is part of the effort presently being done in ESRIN in order to achieve the necessary experience for the 
exploitation of the future ESA/ENVISAT mission. In particular the use of NOAA/AVHRR, Nimbus/CZCS and 
Seastar/SeaWiFS allow to: generate long time series of data, develop new algorithms, experiment the usefulness 
of data products in term of content amount of data as well as format and media for distribution, to test the data 
distribution modalities vis-a-vis the user application and finally to promote the user exploitation of new data. 
This experience can fruitfully used for the MERIS and AATSR as the spatial and spectral resolution of the five 
instruments is close as well as their potential applications.
