EUMETSAT Missions MTG / Infra-Red Sounder (IRS)

• The IRS products are vertical temperature and humidity profiles (L2) over the Earth disc, with 30 minutes refresh rate over Europe.

• The IRS is an imaging spectrometer, based on a Michelson interferometer.

• 2000 spectral samples for every spatial sample.

• The IRS is designed and built by Kayser-Threde (Munich).

LWIR MWIR

9 TEMPO Science Team Meeting, Washington, 1 – 2 June, 2016 Slide: 9

• Main performance parameters (L1): • Spatial resolution: 4 km • split in two non contiguous bands:

• 680 cm-1 to 1210 cm-1 (LWIR band) • 1600 cm-1 to 2250 cm-1 (MWIR band)

• Spectral resolution: 0.625 cm-1

• NEdT: around 0.2 K • Repeat cycle:

• Earth disk: 1 hour • Europe: 30 min

• Budgets: • Envelope: 1.4 x 1.6 x 2.2 m3 • Mass: 400 kg • Power consumption: 650 W • Data rate: 180 Mbits/s

EUMETSAT Missions MTG / Infra-Red Sounder (IRS)


Sentinel-5 will build on the heritage

from the

GOME/SCIAMACHY/GOME-

2/OMI series of instruments on

Envisat, Metop and Aura and

will provide continuity with

these instruments.

The spatial resolution will be

significantly improved as

compared to previous missions,

which is important to support

development of air quality

applications.

Slide: 10

The EPS Second Generation system

is a two-platform system.

EPS-SG A platform: optical imaging,

infrared and microwave

sounding; aerosol imaging, radio

occultation missions and the

Copernicus Sentinel-5 mission.

EPS-SG B platform: microwave and

sub-millimetre-wave imaging,

scatterometry and radio

occultation.
