[Termes IGN] zone intertropicaleRésumé : (Auteur) Results provided by two different assimilation methodologies involving data from passive and active space-borne microwave instruments are presented. The impact of the precipitation estimates produced by the TRMM Microwave Imager (TMI) and Special Sensor Microwave/lmager (SSM/I) in a previously developed 1D variational continuous assimilation algorithm for assimilating tropical rainfall is shown on two hurricane cases. Results on the impact of the SeaWinds scatterometer on the intensity and track forecast of a mid-Atlantic hurricane are also presented. This work is the outcome of a collaborative effort between NASA and NOAA, and indicates the substantial improvement in tropical cyclone forecasting that can result from the assimilation of space-based data in global atmospheric models.

[Termes IGN] satellite d'observation de la TerreRésumé : (Auteur) The accurate prediction and observation of the ice masses at the poles, and particularly of their rates of change, is of interest to us all, not least because 5% of the Earth's population live just 1 meter above sea level. Native Arctic populations face profound changes to their way of life and even existence. Economic interest, associated with oil and gas and trans-Artic shipping, will grow as the pack ice declines, as too may strategic concerns over the sovereignty of the Arctic Ocean. The loss of pack ice may also affect the circulation of the Atlantic, and with it winter weather of western Europe. CryoSat is ESA's first mission dedicated to the observation of the Earth's polar ice masses. Its goals are to determine if there is indeed a downward trend in the mass of artic sea ice, and wether we should regard Antarctica as under threat from global warming.

[Termes IGN] validité des donnéesRésumé : (Auteur) The preceding articles [A05275 and A05276] have described how the CryoSat mission came about, how it was designed, and how the satellite was put together. Little has been yet said about how we will plan the operations, or about the data that will flow to the scientific community. This last article therfore describes those parts of the overal system that will not be launched into space. They include the control and processing centres, as well as less material things like the operations concept and the approach to validation. CryoSat was conceived with clear ideas about the scientific potential of the measurments it would produce. Now shortly before launch, we have accepted 80 proposals from scientific groups who want to exploit this potential, and this article concludes with some examples.

[Termes IGN] satellite d'observation de la TerreRésumé : (Auteur) In the preceding article (A05275), Prof. Duncan Wingham has outlined the genesis of CryoSat, its scientific objectives and its programmatic constraints. The mission objectives are characterised by the determination of small height-related changes over a three-year period. This imposes requirements on the type of measurements to be made, the physical stability of the system, control of the measurement configuration and consistency in the data processing system. The programmatic constraints on the other hand, may be simply characterised as the need for a relatively short development cycle with a stringent cost ceiling. CryoSat is a fully integrated system in which all of the elements have been developed together within the programme to ensure the control needed to satisfy the mission objectives. However, in the interests of readability, the system's description has been split over two articles : this one describing the elements that are to be launched into space, and the following one those parts that will remain on Earth.
