Belarusian scientists design spectral radiometer for space satellites
MINSK, 26 April (BelTA) – Scientists of the Belarusian State University have designed a unique device for studying Earth s atmosphere from the outer space. The three-band spectral radiometer MSR-09 is designed to be mounted on nano satellites in order to study the content of trace gases in Earth s troposphere by measuring solar radiation absorbance spectrum, the university s press service told BelTA.
The spectrometer uses three sensors that focus on different optical bands. They register diffuse solar radiation that passes through layers of the atmosphere in the vertical direction and the horizontal one. The vertical scheme of solar radiation input allows studying the quantity of gases and aerosols while the horizontal one examines their distribution in the atmosphere. The collected data is stored in a microcontroller and beamed down to Earth s surface for further processing.
