Solar radiation monitoring instrument for monitoring solar irradiance variation that is made up of
absolute radiometer RTHK, commercial radio, press at an angle. When the satellite flies out of the
Earth's shadow near the North Pole, and the sunlight enters the field of view, the radiometer begins
the solar irradiance observations. Two radiometers operate continuous observation, and the other one
operates discontinuous observation for calibration of the continuous observation equipment.
Everyday makes 14 times of the atmosphere top global solar irradiance observations.
