Measurement Definition: Flux of short-wave radiation from the Earth’s surface - Physical unit: [ W/m2 ] - Accuracy unit: [ W/m2 ].

Instrument	Status/ Accuracy	Instrument Description	Measurement Technology	Timeline
ERS	Operational	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
NISTAR	Operational	Measure the energy emitted and reflected by the Earth.	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
WildFireSat Sensor	Being developed	Measurements are: Fire Radiative Power (FRP) for hotspot locations. Data products generated: 1) Fire maps showing location, extent, and timing of forest fire events; 2) Fire characteristics, such as fire line intensity and rate of spread; 3) Information enabling air quality modeling of wildland fire events; 4) Mass of carbon released into atmosphere due to biomass burning.	n/a
