| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| ABI | Operational | Detects 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 |  |
| CERES | Operational | Long 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 | |
| CLARA | Operational | CLARA is a scientific instrument that will be used to determine the total solar irradiance of the Sun. | n/a | |
| ERM-2 | Operational | Measures Earth radiation gains and losses on regional, zonal and global scales. | n/a | |
| GOME-2 | Operational | Measurement of total column amounts and stratospheric and tropospheric profiles of ozone. Also amounts of H20, NO2, OClO, BrO, SO2 and HCHO. | n/a | |
| SIM-2 | Operational | Solar irradiance monitoring. | n/a | |
| SIMBA Instrument | Operational | Achieve 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 | |
| TSIS-1/SIM | Operational +/-0.2 % | Measures solar spectral irradiance in the 0.2 - 2 µm range. | n/a | |
| TSIS-1/TIM | Operational +/-0.035 % | Measurement of total solar irradiance directly traceable to SI units with an absolute accuracy of 0.035% and relative accuracy of 0.002% per year. | n/a | |
| CSAR | Being developed | Primary Standard for Solar radiation, traceable to SI units, provide very high accuracy (goal 0.03% ARA) TSI (Total Solar Irradiance) measurements | n/a | |
| GXI | Being developed | Detects 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 | |
