Étude globale des gradients troposphériques déterminés par GNSS et développement d'une chaîne de traitement pour la tomographie 3D

Abstract : The scientific community demonstrated that the GNSS systems may be used for meteorological purposes using the tropospheric parameters. One of them, gradients are taking into account the non-homogeneity of the troposphere around GPS station. This report presents the study carried out on the behavior of these last ones according to the geographic environment of the station. They have a certain temporal stability in their direction. This last one is mainly due to a factor: the relief. On the other hand, these gradients allow to improve the punctual determination of the contents in water vapor integrated upright on a zone covered by permanent stations GNSS. This report also introduces the establishment of a chain of treatment for the GNSS tomography to restore the 3D field of water vapor from the GNSS observations.
