Instrument:SEVIRI
Agencies: EUMETSAT [Primary]
 ESA
Missions: Meteosat-8
 Meteosat-9
 Meteosat-10
 Meteosat-11
Status:Operational
Type:Multi-purpose imaging Vis/IR radiometer
Description:Measurements of cloud cover, cloud top height, precipitation, cloud motion, vegetation, radiation fluxes, convection, air mass analysis, cirrus cloud discrimination, tropopause monitoring, stability monitoring, total ozone and sea surface temperature
Spatial Resolution: HRV=1 km, All other channels=3 km (spatial sampling distance at SSP)
Swath Width: 9 km swath scannig E-W, moving up S-N a swath width at the end of each swath. Full Disc Coverage (FDC) or Local Area Coverage (LAC) possible.
Wavebands: VIS0.6=0.5975-0.6725 ?m, VIS0.8=0.775-0.845 ?m, NIR1.6=1.57-1.71 ?m, IR3.9=3.7-4.14 ?m, WV6.3=5.8-6.7 ?m, WV7.3=7.1-7.6 ?m, IR8.7=8.5-8.9 ?m, IR9.7=9.52-9.8 ?m, IR10.8=10.3-11.3 ?m, IR12.0=11.5-12.5 ?m, IR13.4=12.9-13.9 ?m, HRV=~0.48-0.91 ?m =unfiltered Si (measured at FWHM)
Technology: Multi-purpose imaging Vis/IR radiometer
Description: Instrument designed to address more objectives by appropriate blending of the characteristics of spectral coverage and resolution, spatial resolution, radiometric accuracy, etc.. Spectral coverage in bands of Vis, NIR, SWIR, MWIR and TIR (0.4-15 Ám). Number of channels from a few to a few tens, separated by dichroics and filters. Channel bandwidths around 10 %. Spatial resolution typically 30m-3 km. Applicable in LEO and GEO.
