3. 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 (3D - 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?
