“…The BOS has a hemispherical field of view (HFOV) and the detector is directly exposed to space without any optical or aperture accessories. In optics, Lambert's cosine law says that the radiant intensity or luminous intensity observed from an ideal diffusely reflecting surface or ideal diffuse radiator is directly proportional to the cosine of the θ angle between the direction of the incident light and the surface normal (Smith, 1966). The Lambertian performance is studied using the part of data obtained during MES, when the satellite is slowly turning away from the Sun-pointing axis to a star in deep space.…”

Abstract. The bolometric oscillation sensor (BOS) is a broadband radiation measurement instrument onboard the PICARD satellite that has been active between 2010 and 2014. The main detector is a thermistor attached black coated surface, which was permanently exposed to space without any optical and aperture accessories. The temperature measurements are used within a transfer function to determine variations in incoming solar irradiance as well as the terrestrial radiation. In the present article, the measurement principle of BOS and its transfer function are presented. The performance of the instrument is discussed based on laboratory experiments and space observations from the PICARD satellite. The comparison of the short term variation of Total Solar Irradiance (TSI) with absolute radiometers such as VIRGO/SOHO and TIM/SORCE over the same period of time, suggests that BOS is a relatively much simpler but very effective sensor to monitor electromagnetic radiation variations from visible to infrared wavelengths.

“…sion was extended for 1.5 years. PICARD has three experiments: SODISM (Meftah et al, 2014a) measures the diameter of the Sun, while PREMOS (Schmutz et al, 2013) and the SOVAP (Zhu et al, 2010;Meftah et al, 2014b) measure the total and spectral solar irradiance (Fig. 1).…”
