Débruitage des séries temporelles de coordonnées de stations de géodésie spatiale : application aux stations DORIS
ondelettes. Les tests effectués ont porté sur l'analyse de séries hebdomadaires de jeux de coordonnées résiduelles de 2 stations DORIS. Les résultats montrent que la plupart des séries sont affectées par un bruit blanc et que la méthode optimale de débruitage

Etude comparative des séries temporelles de coordonnées de stations DORIS issues de trois centres d'analyse
le but de cette étude est de déterminer une(s) solution(s) DORIS (Détermination d'Orbite et Radio positionnement Intégrés par Satellite) adéquate(s) parmi celles fournies par 3 différents centres d'analyse en vue de la réalisation du système de

Data of January, April, July, and October are taken to represent the four seasons in this analysis. For the 100 MB surface, the latitudinal deviation and amplitude at both high and low latitudes change greatly in a year. The maximum deviation
appears at 60 N in January, April and October, and at 30 N in July. The circulation characteristics of October is more similar to winter patterns when compared with those of April. The position of trough and ridge lines for 100 MB surface oscillates in a E

Dendroclimatic reconstruction of april-may temperature fluctuations in the western Himalaya of India since A.D. 1698
The AA. present the reconstruction of mean April-May temperature variations back to A.D. 1698 using ring-width chronologies of Himalayan cedar, Himalayan pine, and Himalayan spruce from the western Himalaya. The most striking feature of the present
reconstruction is the absence of any warming trend in the 20th century. Relationships between the mean April-May temperature for the western Himalayan region, Indian summer monsoon rainfall, and Southern Oscillation Index indicate that the tree-ring chronologies
