Objectives
Answer or improve the knowledge about the following basic questions and statement problems will be the foci of this project:
• 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?
• How to improve precipitation estimation and cloud microphysics description by using conventional and polarimetric radar?

o Why are La Plata Basin MCSs so important?
o ~80% of the surface precipitation of La Plata Basin originates from MCSs (lightning should present the same feature – need to be checked though)
o The precipitation features with highest flash rates are mostly observed over La Plata Basin

Zipser et al. (2006)
o Many advantages of deploying the LMA to Foz do Iguaçu:
o La Plata Basin and Foz do Iguaçu are covered by MeteoSat SEVERI (GOES-R ABI proxy).
o IOP starts October-November/2012 –sensors will already be in Brazil (right after São Luiz do Paraitinga IOP).
o Minimum cost – INPE and SIMEPAR will make the survey, deploy and maintainance of LMA sites.
o SIMEPAR will have an S-band dual-pol radar operational by June/2012 at ~120 km from Foz do Iguaçu.
o Useful 3D total lightning for nowcasting of severe weather under GOES-R Risk Reduction activities.
