CHUVA contribution to CWG
• CHUVA is collecting data from a large variety of convective
systems over Brazil:
•
Several Golden Cases from tropical convection trough large MCSs
• Brazil is observed both by GOES and MSG:
•
Great environment for GOES-R and MTG activities:
• Risk Reduction (nowcasting algorithms)
• Algorithm Working Group (proxy data)
• Calibration/Validation
• We are open to additional measurements:
•
You can bring your instruments to the field experiments
• CHUVA data is openly available for the research community:
•
Collaborations are greatly welcome!!!
