Summary:
This study is within the research framework of Global Observation of Precipitation. It is important to verify the satellite precipitation estimates to see how useful they could be for a better understanding of the hydrological cycle and eventually for the benefit of society. It is thus expected to take advantage of hydro-meteorological products derived from remote satellite sensors combined with measurements at land surface.

Several basins in the world, especially in developing countries, need to increase the number and extension of their meteorological stations on land, which is not always feasible due to accessibility, initial investment costs and maintenance. The advantage of satellite precipitation is the coverage taking into account the spatial and temporal distribution in a complementary way to the point measurements with rain gauges and in some scarce regions.

This project has 3 main objectives:
- Evaluation of satellite precipitation products in the available rain gauge networks.
- Development of a new database with greater spatial and temporal resolution.
- Application of the new improved precipitation products to carry out hydrological simulations and thus estimate the water balance in the basins of Bolivia and South America.

The main funding source is the Japanese aero-space exploration agency (JAXA). JAXA will provide all the satellite products necessary for study in addition to the travel costs to attend the scientific meetings of reports and exchange of ideas.

The period of this project is from April 2016 to March 2019.
