ABIOperationalDetects clouds, cloud properties, water vapour, land and sea surface temperatures, dust, aerosols, volcanic ash, fires, total ozone, snow and ice cover, vegetation index.n/a
AMIOperationalContinuous monitoring capability for the near real-time generation of high-resolution meteorological products and long-term change analysis of land/sea surface temperature and cloud coverage.n/a
AVHRR/3OperationalMeasurements of land and sea surface temperature, cloud cover, snow and ice cover, soil moisture and vegetation indices. Data also used for volcanic eruption monitoring.n/a
CERESOperationalLong term measurement of the Earth's radiation budget and atmospheric radiation from the top of the atmosphere to the surface; provision of an accurate and self-consistent cloud and radiation database.n/a
MISROperationalMeasurements of global surface albedo, aerosol and vegetation properties. Also provides multi-angle bidirectional data (1% angle-to-angle accuracy) for cloud cover and reflectances at the surface and aerosol opacities. Global and local modes.n/a
SIMBA InstrumentOperationalAchieve a high absolute accuracy by employing the same instrument for the very first time to measure irradiance from both the Sun and Earth. The CubeSat will turn from our planet to deep space – for calibration purposes – then to our parent star.n/a
