Using Black Carbon as Tracer to Track Pollution from Cooking[Aug 20, 2019]
Prof. SUN Yele and his team at the Institute of Atmospheric Physics found that black carbon was a good tracer to separate HOA and COA. By applying the BC tracer method to several datasets in megacities of Beijing and Nanjing, they found that COA contributed 15-27% to total organic aerosol in summer and even more than 10% during heating period with a significant enhancement of coal combustion emissions.
Split Mineral Fertilizer Application Decreases Straw Mineralization and Priming Effect in Paddy Soil[Aug 19, 2019]
Researchers from the Institute of Subtropical Agriculture quantified the decomposition of 13C-labeled straw and the priming effect governed by the N and P fertilizer application pattern during a 100-day experiment in a flooded soil and discovered that the split N and P addition decreased straw mineralization and priming effect of a paddy soil.
Scientists Evaluate Accuracy of Two Daily-Precipitation Products over Qinghai-Tibet Plateau[Aug 16, 2019]
A research group from Northwest Institute of Eco-Environment and Resources evaluated the accuracy of two long-term satellite-based quantitative rainfall estimate products in daily scale by comparing them with 104 rain gauges over the Qinghai-Tibet Plateau.
Scientists Assess Reliability of Multiple Precipitable Water Vapor Datasets in Central Asia[Aug 16, 2019]
According to scientists from the Institute of Atmospheric Physics, The ERA5, the new generation reanalysis of European Centre for Medium-Range Weather Forecasts (ECMWF), is the most reliable in revealing the spatiotemporal characteristics of precipitable water vapor (PWV) in Central Asia.
Northern Tropical Dry Trend May Just Be Normal Variation: Scientists[Aug 13, 2019]
New rainfall research has shed some light on this question, but left the final answer up in the air. Recently, an international team led by Prof. TAN Liangcheng from the Institute of Earth Environment (IEE) developed a 2700-yr rainfall record of the northern central Indo-Pacific region.
China's Drylands and Deserts Are Expanding[Aug 12, 2019]
Researchers have found that desertification has rapidly increased in China. Drylands cover approximately 50 percent of the land surface in China, among which semi-arid regions are the main dryland type. However, these semi-arid regions have undergone continuous expansion and a significant drying trend in recent decades.
