China's carbon dioxide monitoring satellite TanSat has 75 data users worldwide, according to the website of the Chinese Academy of Sciences.

中科院官网显示，中国CO2监测卫星TANSAT在全世界有75个数据用户。

The 620-kg satellite received 11,000 data orders and 27,478 GB of data downloads.

TanSat, launched last December, was China's first satellite to monitor greenhouse gas emissions¹.

As part of its three-year mission, TanSat thoroughly² examines global carbon dioxide (CO2) levels every 16 days, accurate within 4 ppm (parts per million).

The satellite can observe the sun, moon, solar flares³ and objects on the ground.

The satellite has different modes for observing oceans and land, and can constantly adjust its orientation⁴ and position. To ensure the accuracy of TanSat, six ground-based observation stations will calibrate⁵ and examine observational data.

China is the third country after Japan and the United States to monitor greenhouse gases using its own satellite.
