Mapping of spatially explicit distribution of solar radiation . using the digital elevation model ( dem ) data as input , the distribution of extraterrestrial radiation and possible sunshine duration from january to december were mapped both for chongqing ( resolution of 100m x100m ) . integrated with kt and kb , the distributions of direct and diffuse radiation were also mapped for long - term mean 太陽輻射空間分布研究利用dem數(shù)據(jù),完成了重慶市100m 100m各月天文輻射和可照時間的空間制圖;結(jié)合晴空指數(shù)、直接透射率的模擬結(jié)果,分別完成了氣候平均狀況下重慶市100m 100m的起伏地形下各月太陽直接輻射、散射輻射空間制圖。
Based on the geometry between sunshine ray and real terrains , the distributed models were developed to simulate the extraterrestrial radiation and possible sunshine duration over rugged terrains respectively . according to the principles of direct and diffuse radiation on tilted surfaces , the distributed models to estimate the direct and diffuse radiation over rugged terrains were developed also . the proposed models were proved to be able to treat volumes of data and are applicable to satellite image processing platforms or geographic information system ( gis ) 起伏地形下太陽輻射分布式模型研究根據(jù)太陽光線與實際地形之間的幾何關系,建立了起伏地形下天文輻射、可照時間的分布式估算模式;依據(jù)坡地直接輻射和散射輻射機理,分別建立了起伏地形下直接輻射、散射輻射的分布式估算模式;建立的分布式模式計算結(jié)果可靠,可進行大數(shù)據(jù)量處理,適用于遙感圖像處理、地理信息系統(tǒng)等數(shù)據(jù)處理平臺。
Date integration technique was used to analyze the relationship between monthly mean daily clearness index kt and s , the ration of monthly mean daily sunshine duration to possible sunshine duration as well as that of monthly mean daily direct transmittance kb . based on data from 1957 to 2000 , a series of kt and kb estimation models with different temporal and spatial scales were established . furthermore , the distributions of kt and kb from january to december in chongqing were mapped by kriging interpolation for long - term mean 大氣輻射過程模擬通過晴空指數(shù)、直接透射率等綜合描述大氣對太陽輻射影響的參數(shù),采用重慶市及其周邊地區(qū)1957 - 2000年日射站觀測的月輻射資料和常規(guī)月氣象觀測資料,利用數(shù)據(jù)集群技術,建立了不同時空尺度的太陽輻射估算模式;使用kriging插值法,完成了重慶市氣候平均狀況下各月晴空指數(shù)、直接透射率的空間制圖。
