BackForwardInstrument:  ERS (UVSQ) 

Instrument details
Acronym ERS (UVSQ)
Full name Earth Radiative Sensor
Purpose To measure outgoing LW and SW radiation from the Earth.
Short description

The 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.
