| Zusammenfassung |
| The Bolometric Oscillation Sensor (BOS) is a broadband radiation measurement
instrument onboard the PICARD satellite that was 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
the 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 the BOS
is a relatively much simpler but very effective sensor for monitoring
electromagnetic radiation variations from visible to infrared wavelengths. |
