The National Natural Science Foundation of China initiated a major research program to study formation and response mechanism of Air Pollution Complex in China. Through the program’s 76 projects, scientists have achieved tremendous advances in air pollution research. To raise awareness of air pollution complex, the journal Advances in Atmospheric Sciences recently published a special issue on the topic.

Weather, climate and hydrometeorology forecasts require accurate surface-atmosphere coupled modeling, but arbitrary reference heights have been used in computing surface turbulent fluxes. A team of atmospheric scientists have found optimal coupling heights for improved surface-atmosphere modeling.
