Conclusions and way forward 2/2
•The data volume generated by MTG is much higher than by MSGg y• Issues and questions on:
Capacity for dissemination of MTG data ando Capacity for dissemination of MTG data and products to users
o Data processing/interpretation capabilities at users’ level
• An effective way to prepare for MTG is to intensively exploit and develop MSG applications
