China on Wednesday launched Gaofen 5, a hyperspectral imaging satellite, aboard which are three instruments made by an institute in East China’s Anhui province.
As the first China-developed satellite that can monitor air pollution, Gaofen 5 was launched off the back of a Long March 4C rocket at 2:28 am Beijing Time from the Taiyuan Satellite Launch Center in northern Shanxi province, according to Xinhua News Agency.
The satellite is equipped with three instruments developed by Anhui Institute of Optics and Fine Mechanics, an institute under the Chinese Academy of Sciences (CAS), namely, an atmospheric trace gas differential absorption spectrometer, a greenhouse gas monitor and an atmospheric aerosol multi-angle polarimeter.
They can not only take photos of the earth, but also dynamically reflect the state of air through the monitoring of air pollutants, greenhouse gases and aerosols.
With field views of 114°and 120°respectively, the atmospheric trace gas differential absorption spectrometer and the atmospheric aerosol multi-angle polarimeter are able to obtain global data in just a day, experts say.
