FCI – Benefits from new Channels
Th 0 444 d th 0 51 h l t l iThe 0.444 µm and the 0.51 µm channels: true colour images , improved aerosol retrievals.
The 0.91 µm channel: daytime total column precipitable water.
The 2.26 µm channel: improved retrievals of cloud microphysics.y
The 1.375 µm channel: improved detection of very thin cirrus clouds.
The higher spatial resolution of the 3.8 µm channel: improved fire detection.
Benefits from improved time resolution

Moving from MSG to MTG era
• Some new MTG products to complement the current MSG productsthe current MSG products
• Challenges in capacities (data• Challenges in capacities (data, dissemination, etc) (RAIDEG)
• The Lightning Instrument completely new tool for monitoring convection and thunderstorms in real-timeu de s o s ea e
MTG - Lightning Imager
Lightning – Why do we observe it?Lightning is a precursor of severe weather – total lightning is the parameter to observeparameter to observe
S th d li ht i t ikSevere weather and lightning strikes are a big threat to public (and not
only to aviation)
Long-term lightning g g gcharacteristics help
assess the impact of climate change onclimate change on

Lightning Imager – Benefits Summary
• Complements the global ground based systems. • Improves the quality of information essential for air• Improves the quality of information essential for air
traffic routing and safety.• H l th i t f li t h• Helps assess the impact of climate change on
thunderstorm activity.• Improves very short range forecasts of convective
events.
• Assists in verification/validation of nowcast algorithms (convective initiation)algorithms (convective initiation).
User needs vs MTG capacities
Reference to WMO Survey Feedback on the use of Satellite Data
Recent ASMET (African Satellite Meteorology ( gyEducation & Training) survey feedback:
o The most challenging weather events:o The most challenging weather events: convection, fog, dust
o Sector related challenges: sustainableo Sector-related challenges: sustainable development; agriculture; marine customers; general public; health impacts; airline industrygeneral public; health impacts; airline industry
User Needs on Training
The offices most need training on: ○Using satellite data to detect and monitor○Using satellite data to detect and monitor
convection, fog, and dust Understanding single channels and prod cts○Understanding single channels and products better
○Using new satellite products○Using RGBs○Using satellite data in the forecast process○Using satellite data in conjunction with NWP○Using satellite data in conjunction with NWP
Conclusions and way forward 1/2
• MTG offers more information, improved resolution and more applications compared to MSGpp p
• MTG Missions will:oensure continuation and improvement of existing
servicesservicesoenable new services expected for decades to
comecomeoenhance information on hazardous weather, fires,
l i h ti tvolcanic ash eruptions, etc.Slide: 23
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
