In the context of ERBE and ISCCP data, measured and calculated surface net radiation, investigation is performed of the climatic features of atmospheric net radiation (ANR) over China, along with the relations to its components and affecting factors. Results show that a higher linear correlation exists between ANR and atomsphere-absorbed short-wave radiation is available and thereby a general expression for ANR is formulated based on the relations. A significant tendency of ANR decrease versus altitude and weak increase as a function of latitude in summer is found, with uniform variation in winter. Finally, comparison indicates great difference in ANR pattern and magnitude between our findings and literature.
