Gaofen 10 type.

WMO OSCAR shows FY-3F as launching in December 2022 - however a few other weather satellites are also marked as such and I'm not sure all of them are accurate.

So that's indeed Daqi-1.
This message reflects my personal opinion based on open sources of information.

Regarding the satellite, I have found this paper (which calls it the Atmospheric Environment Monitoring Satellite, AEMS) from several years ago but the instrument suite seems to have changed a bit since then. It's in a 705 km altitude SSO at 2.6 tonnes mass.

If someone knows what do the 5 instrument's abbreviation means (it must be in some academic meeting presentation, somewhere over the past few years), please post it here.

Atmosphere-1 is versatile and technologically advanced, and one satellite is equivalent to several satellites from other countries. Atmosphere-1 is equipped with five remote sensing instruments including atmospheric detection lidar, high-precision polarization scanner, multi-angle polarization imager, ultraviolet hyperspectral atmospheric composition detector and wide-field imaging spectrometer, which can greatly improve global carbon monitoring and atmospheric pollution monitoring. ability.
This is Daqi-1.

ACDL = Aerosol and Carbon dioxide Detection Lidar
DPC-II = Directional Polarimetric Camera
EMI-II = Environmental Trace Gas Monitoring Instrument
POSP = Particulate Observing Scanning Polarization
WSI = Wide Spectral Imager

It seems Daqi-1 is essentially a version of Gaofen 5 with a lidar.

China Remote Sensing Satellite Ground Station Successfully Received Atmospheric Environment Monitoring Satellite Data

On March 21, the China Remote Sensing Satellite Ground Station (hereinafter referred to as the "ground station") of the Institute of Aerospace Information Innovation, Chinese Academy of Sciences successfully received data from the atmospheric environment monitoring satellite.

At 11:46 am, the ground station Miyun station successfully tracked and received the downlink data of the atmospheric environment monitoring satellite, which is also the first downlink data after the satellite was launched. After that, the ground station Sanya station also successfully completed the satellite data reception task as planned at 13:17 and 14:55 respectively. The total data duration of the three receiving tasks is 24 minutes and 24 seconds, and the data volume is about 133 GB. All data are processed normally.

The atmospheric environment monitoring satellite was successfully launched on April 16. It is a scientific research satellite in the "National Civil Space Infrastructure Medium and Long-term Development Plan (2015-2025)". The carbon dioxide detection lidar it carries is the world's first launch. The ground station is responsible for the data receiving task of the satellite.

Aerospace Science and Technology Group develops atmospheric environment monitoring satellite Qi-1 and goes online

On April 16, the ChangsiC rocket was successfully launched from the Taiyuan Satellite Launch Center. This time, the gold medal "space train" is the atmospheric environment monitoring satellite (referred to as Atmosphere-1), which is the world's first carbon dioxide laser detection satellite. On the 705-kilometer sun-synchronous orbit, the 2,600-kilogram Atmosphere No. 1 has started to work, which will greatly improve the global carbon monitoring and large-scale high-precision monitoring of atmospheric pollution, and realize the leap-forward development of my country's atmospheric remote sensing technology.

Before the launch of the Atmosphere-1, passive monitoring of carbon emissions was adopted internationally. The so-called passive monitoring is to use the payload to analyze the received reflectance spectrum information to determine the level of carbon emissions. This process requires the participation of sunlight. However, because of the Lidar, the atmosphere-1 has got rid of the dependence on sunlight and achieved high-precision global autonomous detection throughout the day.

The launch of Qiqi-1 marks the leap-forward development of my country's atmospheric remote sensing technology. On the one hand, the satellite has achieved high-precision detection of carbon dioxide concentration throughout the day. On the other hand, it is reflected in the use of various means to integrate high-precision stereo monitoring. Fine particulate matter, the data of particulate matter near the ground can be monitored, which is directly related to people's health.

Zhu Wei, chief designer of Qiqi-1, said: "Gas-1 is versatile and technologically advanced. One satellite is equivalent to several satellites from other countries." A variety of channels help the radar identify the surface features of the detection area, whether it is water surface, surface or desert, at a glance.

Zhu Wei revealed that in the future, he also plans to launch the Atmosphere-2 satellite, that is, a high-precision greenhouse gas comprehensive detection satellite. Joint detection can achieve the dual advantages of wide coverage and high precision, and further enhance the level of my country's space-based carbon monitoring capabilities.
