According to the Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS), a research team led by Prof. LIU Liangyun has released global 30-m impervious surface datasets with an accuracy of 95.1 %, the highest accuracy among existing data products of this kind. The related paper has been published in the journal Earth System Science Data, with the title of “Development of a global 30-m impervious surface map using multi-source and multi-temporal remote sensing datasets with the Google Earth Engine platform”.

A research team led by Prof. DI Kaichang from the State Key Laboratory of Remote Sensing Science under the Aerospace Information Research Institute (AIR), partnering with scientists from other institutions, has made detailed analysis by using multiple datasets from the rover's panoramic camera (Pancam), hazard avoidance camera (Hazcam), and the visible and near-infrared spectrometer (VNIS), revealing that the unusual substance is actually an impact melt breccia, and the provenance of the rover measured surrounding regolith might originate from a differentiated melt pool or from a suite of igneous rocks. The research paper "Impact melt breccia and surrounding regolith measured by Chang'e-4 rover" was published in Earth and Planetary Science Letters, a leading journal in the Earth and planetary science community.

How exactly can space information technologies be applied to the research, monitoring and protection of cultural and natural heritage? Wang Xinyuan, deputy director of the International Center on Space Technologies for Natural and Cultural Heritage under the auspices of UNESCO, answered this question in an online lecture where he shared projects and discoveries last month.

At the end of May，an eight-member working group from the Microwave Microsystem Department of the Aerospace Information Research Institute (AIR) conducted an agricultural application flight test in Yushu, Jilin Province, using the S-band subsystem.

Recently, Prof. LI Zhengqiang and his team from the State Environmental Protection Key Laboratory of Satellite Remote Sensing, Aerospace Information Research Institute (AIR) have proposed a new aerosol retrieval algorithm for better FMA retrieval, called Spectral Neutrality of Surface Polarized Reflectance, or SNOSPR for short. The research paper was published in Remote Sensing of Environment, a top academic journal in the remote sensing field.

The Spaceborne Microwave Remote Sensing System Department from the Aerospace Information Research Institute (AIR) has made some progress on using SAR remote sensing technology for pre-disaster deformation monitoring. A research paper titled "Improved Offset Tracking for Pre-disaster Deformation Monitoring of the 2018 Jinsha River Landslide (Tibet, China)", has been published in Remote Sensing of Environment (RSE, IF=8.791), one of the top SCI academic journals in the remote sensing field.
