China launched a global carbon dioxide monitoring satellite via a Long March-2D rocket. It was launched from Jiuquan Satellite Launch Centre in the Gobi Desert. The 620-kg satellite TanSat was sent into a sun synchronous orbit about 700 km above the earth and will monitor the concentration, distribution and flow of carbon dioxide in the atmosphere. The chief designer of the project TanSat is Yin Zengshan at the Chinese Academy of Sciences micro-satellite research institute. The satellite will help in understanding of climate change and provide independent data. During its three-year mission, TanSat will thoroughly examine global carbon dioxide levels every 16 days, accurate to at least 4 ppm (parts per million). China is the third country after Japan and the US to monitor greenhouse gases through its own satellite.
