The net surface solar radiation ( nssr ) as one of the most important portion of global radiation budget has a great action to solar energy absorbed by surface and then affect the surface radiation budget and atmospheric dynamical process 其中地表凈太陽輻射的衛(wèi)星遙感是全球輻射平衡遙感中的一個重要部分,因?yàn)樗砹说乇砦盏奶栞椛淠芰?,對地表輻射平衡和大氣動力過程等有著重要的作用。
The global distribution of nssr can be provided by means of satellite remote sensing . in this paper a new parameterization derived by li zhan - qing ( li model ) in 1995 was used to compute the net surface solar radiation for 18 stations of chinese main land on some days over january and february in 2001 . after compared the results of li model with those derived from a model ( li - leighton model ) and b model ( langley parameter model ) for clear - sky and cloud - sky respectively , we founded that the relative difference of the two model are below 6 % 結(jié)果表明:在晴天情況下, li模式與a模式很相近,而與b模式結(jié)果差別較大,因?yàn)閎模式在晴空條件下是不準(zhǔn)確的,這也可以從a模式與b模式的差別看出;在云天情況下, li模式與b模式結(jié)果盡管有些差異,但是相似性仍然很好,除了個別的臺站外,絕大部分臺站兩者的相對差在6以內(nèi)。
