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
