CHUVA Project CHUVA has the Objective of Answer or improve the knowledge about the following basic question • How to estimate rainfall from warm clouds? • What is the contribution of rain from warm clouds to the total precipitation in different regions of Brazil? • How to improve both space and time precipitation estimation of rainfall over the continent for the GPM constellation? • What are the average characteristics (3 D - cloud processes) of the main regimes of precipitation in Brazil? • What is the contribution of the aerosol in the process of formation of precipitation? • What are the main surface and boundary layer processes in the formation and maintenance of clouds? • How cloud microphysics and electrification processes evolves during the cloud life cycle?
