lations, the relationship between the Asian monsoon and summer rainfall in the Yangtze River Valley and the relationship between the Chinese and Indian monsoons. The objective is to improve understanding of the climate system for long-range forecasting and short-term prediction.
The National Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), set up in 1985, hosts visiting scientists from all over the world. LASG supports climate, ecology, and environmental research by using data sets and computer-assisted analyses. Main topics are the development of four-dimensional dynamic models, data sets, and methodologies and protocols for handling large volumes of data.
The LASG data center holds more than 200 gigabytes, and the volume of data is growing at more than 1 gigabyte per year. The LASG has a CONVEX mini-supercomputer, Silicon Graphics work station, and numerous micro-computers. Data holdings include basic climate variables, trace gas, land-surface properties, ocean variables, past climate change variables, and global and national carbon dioxide (CO2) emissions.
The institute publishes Scientia Atmospherica Sinica (Daqi Kexue, quarterly, in Chinese), Advances in Atmospheric Sciences (quarterly, in English), and the Annual Report of the Institute of Atmospheric Physics.
The CAS Institute of Botany is located in pleasant surroundings on the grounds of the Beijing Zoo. The institute is under the leadership of Zhang Xinshi (also known as Chang Hsin-shih and David Chang), who replaced the distinguished Tang Peisung upon his retirement. The institute is large, effectively managed, and covers a wide array of botanical sciences. It has sections dealing with phytochemistry, cytology, nitrogen fixation, photosynthesis, plant physiology, and plant ecology/geobotany. It has the largest herbarium in Asia, with collections predating the 1920s. The professional staff is 580, with a support staff of 200. Approximately 50 M.S. and 20 Ph.D. students are working in the institute. The institute administers three CERN sites: (1) the Inner Mongolia Grassland Ecosystem Experiment Station, (2) Beijing Forest Ecosystem Experiment Station, and (3) Maousu Ecology Experiment Station. The institute is working with the CAS Lanzhou Institute of Plateau Atmospheric Physics and the CAS Lanzhou Institute of Glaciology and Geocryology to establish a research station on the Qinghai-Tibet Plateau.
