| Título: | Tomographic determination of the spatial Distribution of Water Vapor using GNSS observations. |

| Resumo: | This paper focuses on investigating Global Navigation Satellite Systems (GNSS) observations as precipitation sensors and also analyse the contribution of the GNSS dense networks as an efficient tool for meteorological purposes based one Water Vapor Tomography. For that, case-studies are presented using data from BELEM and MANAUS dense network.
For Water Vapor Tomograhy, a software package has been developed to reconstruct the GNSS water vapour spatial distribution. The obtained results indicate that GNSS can detect the variations in precipitation at different periods of the year and that dense GNSS networks allow us to generate images of the spatial and temporal distribution of water vapour. However, the influence of several parameters, such as number and distribution of receivers, grid sizes and initial values, has to be taken into account for the image reconstruction. |
