This study compares the aerosol optical depth (AOD) Level 2 Collection 5 products from the Terra and Aqua Moderate Resolution Imaging Spectroradiometers (MODIS) with ground-based measurements from a Microtops II sun photometer over Sanya (18.23°N,109.52°E),a tropical coastal site in China,from July 2005 to June *** results indicate that the Terra and Aqua MODIS AOD retrievals at 550 nm have good correlations with the measurements from the Microtops II sun *** correlation coefficients for the linear regression fits (R2) are 0.83 for Terra and 0.78 for Aqua,and the regressed intercepts are near zero (0.005 for Terra,0.009 for Aqua).However,the Terra and Aqua MODIS are found to consistently underestimate AOD with respect to the Microtops II sun photometer,with slope values of 0.805 (Terra) and 0.767 (Aqua).The comparison of the monthly mean AOD indicates that for each month,the Terra and Aqua MODIS retrievals are matched with corresponding Microtops measurements but are systematically less than those of the *** validation study indicates that the Terra and Aqua MODIS AOD retrievals can adequately characterize the AOD distributions over the tropical coastal region of China,but further efforts to eliminate systematic errors are needed.

随着数字网络的快速发展,信息技术的革新呈现出周期渐短、功能渐全的趋势。在媒介营造的社会文化环境下,社交媒体(SNS)已成为人们社会生活中重要的组成部分,在给人们带来各种便利的同时,也对其工作、生活、心理等方面造成了不可忽视的... 详细信息

随着数字网络的快速发展,信息技术的革新呈现出周期渐短、功能渐全的趋势。在媒介营造的社会文化环境下,社交媒体(SNS)已成为人们社会生活中重要的组成部分,在给人们带来各种便利的同时,也对其工作、生活、心理等方面造成了不可忽视的负面影响。尽管如此,人们使用社交媒体的热情和频率在担心与抱怨中依旧高涨不减。基于此种矛盾的现象,本文试图从社会心理学的角度关注人们使用社交媒体的内在动机,进而对社交媒体依赖原因进行探析,以期人们能够清醒而理性地认识个体本身与社交媒体的关系,扬其长避其短,恰当地利用社交媒体为个人及社会创造价值。
