Surface albedo plays a key role in the energy and water cycles, and reasonable parameterizations of surface albedo will be greatly helpful to improve the simulation of radiation partition in climate models. In‐situ measurements of albedo from five sites over the Tibetan Plateau (TP) and MODIS albedo product are used to evaluate monthly, annual, and seasonal variations of the surface albedo simulated...
Many complex networks in the real world demonstrate similar patterns, including the scale-free property and strong community structure. In this paper, we present a novel parameter-free community detection algorithm based on the scale-free property of networks, named ScaleFreeCDA. The basic idea behind it is two mechanisms, i.e., node growth and preferential attachment. Community centers are firstly...
The principle of laser scanning ranging is applied in this paper. A reasonable algorithm is used to make laser sensor calibration. In this article, spatial coordinate system is established to analyze the measured data. Then we get the space coordinates of the scanning points and the data of pavement profile points in the laser scanning plane. Finally, the pavement roughness test result is obtained.
