| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| NISTAR | Operational | Measure the energy emitted and reflected by the Earth. | n/a | |
| CWFMS | Being developed | Measurements are: Fire Radiative Power (FRP), hotspot locations, rate of spread, burned area mapping. Data products generated: 1) Fire maps, showing location, extent, and timing of forest fire events; 2) Fire characteristics, such as fire line intensity, rate of spread and fuel consumption; 3) Plume dynamics through smoke transport maps and plume heights; 4) Mass of carbon released into atmosphere. | n/a | |
| ERS | Being developed | ERS are sensors based on miniaturized thermopiles (active area of 5 mm × 5 mm, responsivity of ∼ 0.2 μ V per Wm−2 ) designed to measure the heat flux from a 180° field of view angle. | n/a | |
| HIS | Being developed | Pushbroom-type dual-prism Imaging Spectrometer with high radiometric accuracy and medium Signal-to-noise Ratio, operating from UV (320 nm) to SWIR (2400 nm) , based on a single MCT Detector/focal plane. The HIS aims at accurate spectral imaging on land and ocean for climatological background radiometric data acquistion and supporting cross-calibration with other stellites/sensors and on PICS/instrumented sites with highest resolution (50 m) | n/a | |
| Libera | Being developed | 5-year design mission. The mission focuses on understanding the flow of energy out of the planet and how it changes over time. | n/a | |
