The solar wind is a stream of plasma ejected from the upper atmosphere of the Sun, carrying the Sun's magnetic field through the heliosphere. The interaction of the solar wind and its transients with the Earth's magnetos...

Under the successive funding of two National 973 programs in the frontier area of key scientific research, we proposed the new theory that mineral photoelectrons are the third energy form on earth surface, and they can p...

Orogenies are the most important geological processes on the earth that form huge orogens, and such processes can be classified into two categories: collisional orogenies and accretionary orogenies, which are represented...

The increasing availability of multi-sensor data and related spatial data provides abundant data sources for diverse applications. To meet vital scientific and economic demands, we have been working on extraction of disa...

Understanding the interaction mechanism between electromagnetic waves and ground targets is a primary task for intelligent processing and quantitative inversion of multi-source, multi-band remote sensing data, and genera...

In the area of smart earth, we carried out a series of leading work on smart earth framework, smart city and smart coalmine applications.

The advent of Big Data Era and the emergence of various and massive spatial-temporal data bring the new challenges and chances to the research of geographic information science. Considering that humans are the center of ...

Research Institute of Theoretical and Applied Geophysics, Peking University has developed a series of techniques about multiple attenuation methods including adaptive beamforming, inverse series, constructing virtual eve...

Zheng-Kang Shen and his team have been using space geodesy methods to study crustal deformation. Based on the observations they developed models for better understanding of the tectonic deformation mechanisms and physica...

The research interest of Prof. Qinghua Huang’s group includes geoelectromagnetism and statistical seismology, with particular focus on physics and monitoring of nature hazards such as earthquakes and landslides.

Magnetic null is the fundamental element of magnetic reconnection in plasma, which together with the ambient 3D topology is crucial for developing the magnetic reconnection theory. Scientists have been pursuing the magne...

Energetic electrons in Earth's magnetosphere will cause severe damage to the satellites and spacecraft, they are usually known as 'killer electrons'. Dramatic increase of killer electron flux (i.e., energetic electron st...
