I could be wrong, but this this has all the indications to me of being a cover story for a spy satellite. The artist rendering (below) they provide with the press release shows the satellite imaging a ground based communications facility, rather than probing the atmosphere.That looks like an accidental slip in the PR. Lest you think I’m paranoid, there is precedence for this, NASA reports another Chinese program that looks like the USLANDSAT program, appears to have military capabilities:
The ZiYuan program appears to cover different civil and military earth observation – as well as remote sensing – programs. The ZiYuan-1 program is focused on Earth resources and appears to have two distinct military and civil branches
Given that China’s government doesn’t seem all that concerned about their rapidly rising CO2 emissions, and China is currently burning four billion tons of coal per year compared to the U.S. use of one billion, one wonders why they’d bother to monitor it. Seems like a perfect ruse, especially since China has recently begun what appears to be a cold war style build up of military programs, including building islands at sea solely for military purposes.

A cloud-screening scheme for for the Chinese Carbon Dioxide Observation Satellite (TanSat)
Carbon dioxide (CO2) is one of the major greenhouse gases, and causes great concern due to the rapid increase in its atmospheric concentrations. China launched its first minisatellite dedicated to the carbon dioxide detection and monitoring at 15:22 UTC on December 22, 2016. The Chinese Carbon Dioxide Observation Satellite (TANSAT) was designed to focus on the global observation of CO2. For retrieving carbon dioxide from TANSAT observations, cloud detection is an essential preprocessing step.
The TANSAT project is one of the National High-tech Research and Development Programs funded by the Ministry of Science and Technology of the People’s Republic of China and the Chinese Academy of Sciences. During the pre-launch study of TANSAT, a cloud-screening scheme for the Cloud and Aerosol Polarization Imager (CAPI) was proposed by a team at the Department of Atmospheric and Oceanic Sciences, School of Physics, Peking University. They noticed that previous cloud-screening algorithms were basically designed to provide comprehensive utilization for sensors that contain multiple channels over a wide spectral range. However, for TANSAT/CAPI, the channels available for cloud screening cover only five spectral bands, which is why such sensors need a more effective method to regroup results from few threshold tests.
Their work relies upon the radiance data from the Visible and Infrared Radiometer (VIRR) onboard the Chinese FengYun-3A Polar-orbiting Meteorological Satellite (FY-3A), which uses four wavebands similar to that of CAPI and can serve as a proxy for its measurements. The cloud-screening scheme for TANSAT/CAPI, based on previous cloud-screening algorithms, defines a method to regroup individual threshold tests on a pixel-by-pixel basis according to the derived clear confidence level (CCL).
The scheme has been applied to a number of the FY3A/VIRR scenes over four target areas (desert, snow, ocean, forest) in China for all seasons. Comparisons against the cloud-screening product from MODIS suggest that the proposed scheme inherits the advantages of schemes described in previous publications and shows improved cloud-screening results. This scheme is proven to be more efficient for sensors with few channels or frequencies available for cloud screening.
