A research team led by Prof. FANG Guangyou from the Aerospace Information Research Institute (AIR), Chinese Academy of Sciences (CAS) trained and tested a promising detector based on deep residual networks using human image data collected by passive terahertz devices (Figure 1a, b, c). The proposed new method can be used for accurate and real-time detection of hidden objects in terahertz images. The study was published in Scientific Reports.

Four datasets on the Sahel-Sudano-Guinean region of Africa have been recently released on the platform of the National Tibetan Plateau / Third Pole Environment Data Center. The four datasets include: 1) 30m resolution land use/cover the (1990-2020); 2) annual NPP-VIIRS (National Polar-Orbiting Partnership - Visible Infrared Imaging Radiometer Suite) night time light (2013-2020); 3) long time series on night time light on the same region as data set (2), but a much longer period of time (1992-2020); 4) inventory and extent of surface water bodies (2000-2020).
