NASA’s Earth science division, Michael Freilich, met with Chinese officials last month regarding potential coordination between the two countries on an upcoming Chinese mission, the agency said Aug. 4.
The meeting, first reported by the Hong Kong newspaper South China Morning Post but not initially confirmed by NASA, is the latest sign that the space agency is finding ways to work with China despite strict limitations placed by Congress on bilateral cooperation.
“As part of coordination discussions between NASA and the Chinese Academy of Sciences related to Earth science research, Dr. Freilich met with his counterparts at the Chinese Academy of Sciences on July 12, 2016, in Beijing,” NASA spokesman Steve Cole said Aug. 4.
The purpose of the meeting, Cole said, was “to discuss scientific data exchange and China’s plans for the launch of its new carbon monitoring mission, TanSat.” Cole did not disclose the outcome of the meeting, and said “no follow-up activities planned at this time.”
TanSat is a 500-kilogram satellite under development by the Chinese Academy of Sciences to measure carbon dioxide levels in the Earth’s atmosphere. The spacecraft is scheduled for launch late this year on a Long March 2D rocket.

I'm guessing there will be no webcast for TanSat's launch, right?

Yes, I wouldn't expect a webcast.

A point that may be explained in the NSF launch article:
Is there formal or informal cooperation between the various space agencies flying atmospheric carbon dioxide measuring instruments?
In the case of NASA and CAS, how is it accomplished, given the statutory restrictions?
Thank you.

Rui has a great article for this launch, which is naturally specific to the Chinese mission. However, he mentions it has international involvement, including with the UK! :)
-
Two hyperspectral micro-satellites (Spark-01 and Spark-02; Yijian (?)) will ride into orbit together with TanSat.
-
No news yet on the launch; waiting for confirmation here.
-
Xinhua News' Twitter account tweeted that it has been launched, but I still can't find any Chinese source supporting. :-X
(then again it's 4 am on this side of Earth....)

Oh the launch success confirmation has come. T-0 was at 19:22 UTC.

China Focus: China launches satellite to monitor global carbon emissions
Source: Xinhua 2016-12-22 04:06:24
By Xinhua writer Yu Fei
JIUQUAN, Dec. 22 (Xinhua) -- China launched a carbon dioxide monitoring satellite via a Long March-2D rocket from Jiuquan Satellite Launch Center in northwest China's Gobi Desert at 3:22 a.m. Thursday.
China is the third country after Japan and the United States to monitor greenhouse gases through its own satellite.
The 620-kg satellite TanSat was sent into a sun synchronous orbit about 700 kilometers above the earth and will monitor the concentration, distribution and flow of carbon dioxide (CO2) in the atmosphere, said Yin Zengshan, chief designer of TanSat at the Chinese Academy of Sciences micro-satellite research institute.
The satellite will help understanding of climate change and provide China's policy makers with independent data.
On a three-year mission, TanSat will thoroughly examine global CO2 levels every 16 days, accurate to at least 4 ppm (parts per million).
This was the 243rd mission of the Long March series rockets. Besides TanSat, the rocket also carried a high-resolution micro-nano satellite and two spectrum micro-nano satellites for agricultural and forestry monitoring.
FIRST-HAND DATA
The concentration of CO2 in the atmosphere has increased from 280 ppm to 400 ppm over the past 150 years, leading to an increase in average global temperatures of about 0.7 degrees Celsius over the last century, according to Lu Naimeng, TanSat chief scientist.
The new satellite will enable China to obtain emissions data first-hand and share it with researchers worldwide, Yin said.
The Paris Agreement on climate change came into force on Nov. 4, with more than 100 countries committed to reducing their carbon emissions. The satellite can trace the sources of greenhouse gases and help evaluate whether countries are fulfilling their commitments. TanSat means a louder voice for China on climate change, carbon reduction and in negotiations with a bigger say on carbon trading.
Research on the CO2 flow will improve understanding of the carbon cycle, generate more accurate and reliable predictions of climate change.
China's CO2 emissions are to peak around 2030, with emissions per unit of GDP cut by 60 percent of 2005 levels by the same date.
A national carbon trading market will open next year.
WORLDWIDE SCOPE
Many countries are reducing emissions, but calculating how much they are actually doing is difficult. Ground-based monitoring cannot collect accurate data on a global scale, so satellites offer the best means of measuring CO2. Japan and the United States have their own monitoring satellites, but two are far from enough to assess the whole world.
"Since only the United States and Japan have carbon-monitoring satellites, it is hard for us to see first-hand data," said Zhang Peng, TanSat application system commander and vice director of the National Satellite Meteorological Center.
"Before, all our data came from ground stations. That kind of data is both local and limited, and does not cover the oceans," Zhang said.
"The satellite has worldwide scope and will improve data collection. Observing atmospheric CO2 by satellite demands cutting-edge technology, so TanSat is a major technological achievement for China," Zhang said.
"We hope TanSat will work with carbon-monitoring satellites of other countries and provide ample data for studying climate change," said Li Jiahong, chief engineer of the National Remote Sensing Center.
Researchers took almost six years to develop TanSat and its high-resolution CO2 detector.
"The TanSat has very good "vision," and can distinguish changes in atmospheric CO2 as small as 1 percent," said Yin. Cloud and aerosol detectors minimize interference, making observations more accurate.
The satellite has different modes for observing oceans and land, and can constantly adjust its orientation and position. To ensure the accuracy of TanSat, six ground-based observation stations will calibrate and examine observational data.
"We can now collect carbon data from all over the world, all year round, and record the carbon contributed by both developed countries and the developing countries," said Lin Chao who was involved in developing the detectors.
"As for China, we can have detailed analysis on emissions in different regions, provinces and cities, thanks to the satellite," said Lin.

JIUQUAN, Dec. 22 (Xinhua) -- China launched a carbon dioxide monitoing satellite via a Long March-2D rocket from Jiuquan Satellite Launch Center in northwest China's Gobi Desert at 3:22 a.m. Thursday.

Two hyperspectral micro-satellites (Spark-01 and Spark-02; Yijian (?)) will ride into orbit together with TanSat.
The third satellite is also from the same series but with "high resolution" capability. All three were built and to be operated by the China Academy of Sciences' Shanghai Small Satellite Center, which built satellites like BX-2.

Storyline
China launched its first carbon dioxide monitoring satellite early Thursday as part of the efforts to understand, monitor and tackle greenhouse gas emissions.
The carbon tracking satellite, named TanSat, was launched via a Long March-2D rocket from Jiuquan Satellite Launch Center in northwest China's Gobi Desert at 03:22 Thursday morning.
With this launch, China becomes the third country after Japan and the United States to monitor greenhouse gases through its own satellite.
The 620-kg satellite was sent into a sun synchronous orbit about 700 kilometers above the earth and will monitor the concentration, distribution and flow of carbon dioxide (CO2) in the atmosphere, said Yin Zengshan, chief designer of TanSat at the Chinese Academy of Sciences (CAS) micro-satellite research institute.
The satellite will help the understanding of climate change, and provide China's policymakers with independent data.

No name as such, just the description - high resolution multispectral nanosat
I haven't seen the Yijian name in any Chinese source. Space-Track is now using it though

It seems to me that Yijian is a translation error.
In an article by Microsate, there was a quoted line -- “碳卫星工程一箭四星” -- which reads "Tan weixing gongcheng yijian sixing" and means "Tansat project, one rocket, four satellites". I'd guess this "one rocket" -- yijian -- became a satellite name somewhere in a computer translation and made it to the Space-Track catalogue.
-
It was listed as Yijian in the Chinese submission to the UN Registry ST/SG/SER.E/856
-

That's true -- but even in the Chinese original version of the submission the name was written in English without the Chinese equivalent. So I think they just chose to submit the name known from SpaceTrack for simplicity.
