An atmospheric environment monitoring satellite was sent into space by the Long March-4C rocket lifting off from the Taiyuan Satellite Launch Center in Shanxi Province, north China early Saturday.
Five atmospheric environment monitoring payloads are carried on the satellite orbiting the Earth, three of which are developed by the Hefei Institutes of Physical Sciences (HFIPS) of the Chinese Academy of Sciences, namely environmental Monitoring Instrument (EMI), Directional Polarization Camera (DPC) and Particle Observation scanning Polarization Meter (POSP), working independently or collectively to monitor the air pollutants at global scale.
With a maximum field of view of 2,600 kilometers, it can cover the entire earth in one day and has a minimum spectral resolution of 0.6 nanometer, enabling EMI to accurately identify unique information in the absorption spectra and then detect and monitor polluted gases such as nitrogen dioxide, sulfur dioxide and formaldehyde.
For DPC and POSP, researchers at HFIPS proposed an innovative detection program called "Crossfire," which combines the spatio-temporal distribution of global atmospheric aerosols and clouds obtained by DPC instrument and the high-precision atmospheric aerosol parameters obtained by the POSP instrument across orbit.

Diverse life forms may have evolved earlier than previously thought
Saturday, 16 April 2022 07:31 Write a comment
Diverse microbial life existed on Earth at least 3.75 billion years ago, suggests a new study led by UCL researchers that challenges the conventional view of when life began.
For the study, published in Science Advances, the research team analysed a fist-sized rock from Quebec, Canada, estimated to be between 3.75 and 4.28 billion years old. In an earlier Nature paper*, the team found tiny Hughes announces distribution agreement with OneWeb Technologies
