METimage meteorological imager

METimage is a passive optical visible and infrared multispectral meteorological imager on Metop-SG A satellites, previously named the Visible and Infrared Imager (VII). ^[1] The instrument provides 20 visible-to-infrared channels, with channel centres spanning 443 nm to 13.345 um, 500 m nadir resolution for all channels, and an approximately 2670 km swath. ^[1] Its coverage pattern supports global observation twice per day for long-wave channels and once per day for short-wave channels. ^[1] METimage has demonstrated sea-surface temperature retrieval and atmospheric-motion-vector production on Metop-SG A1, pairing broad visible and thermal imaging with meteorological cloud, aerosol, ocean and surface products. ^{[1] [2]} First METimage scenes were captured in September 2025, while commissioning and performance tuning still preceded operational data provision. ^[2] The instrument sits in the Metop-SG imager role alongside the wider atmospheric sounding and microwave payload suite. ^[3]
