Meteosat Second Generation (MSG)

Geostationary satellites

• consists of a series of four geostationary weather satellites

• scheduled to operate consecutively until 2018

• provides important image data on European weather on a daily basis, every 15 minutes through 12 spectral bands

• Meteosat-9 (in operation since 2006) provides data collection and environmental monitoring data

• Meteosat-8 (in operation since 2004) provides Rapid Scan Service (RSS) images every five minutes

• RSS delivers image data and meteorological products for the detection of rapidly developing localised convective weather systems.

Meteosat Third Generation, MTG – The Observations Missions

From the Instruments on board the MTG - I satellites:• the Full Disk High Spectral resolution Imagery (FDHSI) mission,• the High spatial Resolution Fast refresh Imagery (HRFI) mission, • the Lightning Imagery (LI) mission,

From the Instruments on board the MTG-S satellites:• the InfraRed Sounding (IRS) mission,• the GMES Sentinel - 4 (S4) sounding mission.

Slide: 5

Flexible Combined (FC) Imager

• The Flexible Combined Imager supports the FDHSI and HRFI missions.

• Basic repeat cycle of 10 min Full Disk coverage

• The Local Area Coverage zone can be positioned anywhere over the Full Disk Coverage. Possible repeat cycle of 10/2, 10/3 or 10/4 minutes, with the coverage reduced proportionally.

Challenges compared to MSG:• improved Spatial Resolution (0.5 -

2 km)• faster basic repeat cycle (brc = 10

min)• better spectral coverage (more

channels)• improved spectral accuracy• improved radiometric accuracy

MTG IR Sounding Mission

Priorities IRS Mission- Atmospheric dynamic variables with

high vertical resolution (e.g. water vapour flux, wind profile, transport of pollutant gases)

- More frequent information on Temperature and Humidity profiles for NWP (regional and global)

- Monitoring of instability / early warning of convective intensity

- Cloud microphysical structure- support chemical weather and air quality

applications

Hyperspectral IR sounding with focus

on time evolution of vertically resolved water vapour structures

Slide: 8

MTG IR Sounding Mission

Repeat sequence selectable from four Local Area Coverage (LAC) zones.

Each LAC zone covers a quarter of the Full Disc Coverage (FDC), described by a circle of 17.7° centred on the Sub-Satellite Point (SSP)

LAC zone can be positioned anywhere over the FDC.

A LAC zone is scanned within 15 minutes. The full disc is scanned in 60 Minutes

Slide: 9

MTG Lightning Mission

The LI continuously monitors lightning flashes - In Cloud (IC), Cloud to Cloud (CC), and Cloud to Ground (CG) - during day and night, covering an area of the earth disk within a circle of 16° in diameter subtended from the geo-stationary position and shifted northward to cover EUMETSAT member states.

Detection efficiency maximised over Europe [DE=90% for E > 10 mJ.m-2.sr-1 over Europe and 70% elsewhere - to be assessed for energies below 10 mJ.m-2.sr-1]

On ground correction for achieving the specified False Alarm Rate [350/s with 50% cloud cover and 80% albedo (worst case conditions). FAR=2/s after level 1b processing on ground ]

Slide: 10

MTG UVN- S4 Mission for Atmospheric Chemistry

The GMES Sentinel -4 (S4) sounding mission is achieved through the Ultraviolet, Visible & Near-infrared (UVN) Instrument accommodated on the MTG-S satellites– covering Europe every hour – taking measurements in

three spectral bands (UV: 305 - 400 nm; VIS: 400 - 500 nm, NIR: 750 - 775 nm)

– with a resolution around 8km.

The primary data products are O3, NO2, SO2, HCHO and aerosol optical depth. In addition the MTG-IRS is expected to provide information on O3 and CO.
