Instrument	Status/ Accuracy	Instrument Description	Measurement Technology	Timeline
AIRS	Operational	High spectral resolution measurement of temperature and humidity profiles in the atmosphere. Long-wave Earth surface emissivity. Cloud diagnostics. Trace gas profiles. Surface temperatures.	n/a
MISR	Operational	Measurements 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
SLSTR	Operational	Marine and land services.	n/a
ASLSTR	Being developed	Dual-view conical scanner with channels in the VIS, NIR SWIR TIR, supporting a wide range of Marine, Land, Atmosphere and Climate Services. Provides enhanced continutity of SST and LST measurements from SLSTR and enhanced synergy with AOLCI	n/a
CLIM	Being developed	3-band cloud pushbroom imager for detecting low and high clouds in the spatial sample of CO2I allowing to remove these data from the retrieval process.	n/a
CO2I	Being developed	Pushbroom scanning spectrometer to provide relatively high spatial resolution CO2, CH4 and NO2 observations in support of estimating anthropogenic emissions of CO2 and CH4 in Copernicus. In addition, high quality NO2 and solar-induced fluorescence will be operationally delivered.	High-resolution nadir-scanning SW spectrometer
