  skos:definition """The imaging radiometer on the Meteosat Operational Programme (MOP)
series of satellites operated in a visible, infrared, and water vapor
band providing full-disc Earth images in 25 minutes followed by a 5
minute retrace and stabilization period. The imager provided day/night
cloudcover data and visible-infrared radiances for meteorological
applications and weather forecasting. The optical system consisted of
a moveable Ritchey-Cretien 40 cm primary aperature, 365 cm focal
length telescope mounted on two flexible plate pivots attached to a
step motor by a high-precision jack screw via a gear box. The
telescope is stepped 0.125 milliradians every 100 rpm satellite
rotation so that the Earth's surface is scanned at 5 km intervals,
south to north, covering a total angular distance of 18 degrees. Each
infrared (IR) image consists of 2500 lines (each 2500 pixels). The
visible detectors provide 5000-line images corresponding to a
resolution of 2.5 km. The visible silicon photodiode detectors cover
0.4 - 0.9 microns, the thermal infrared HgCdTe detector covers 10.5 -
12.5 microns, and the water vapor-infrared HgCdTe detector covers 5.7
- 7.1 microns.
