AbstractMeasurements of ground displacement have been carried out on the entire active volcanic island of Tenerife, Canary Islands, by means of classical and advanced DInSAR techniques. The main limiting factor on the accuracy of DInSAR measurements is the distribution of the water vapour in the lower troposphere. Hence, it is yet necessary to perform a detailed spatial and temporal characterization of water vapour to understand, and to be able to carry out a direct computation of, the effect of the tropospheric delay on DInSAR results. In this sense, satellite and balloon data have been analysed to infer the variability in the distribution of water vapour and hence, the robustness of DInSAR results on the island of Tenerife.
