differential albedo

Based on the global radiation data as well as the data of spectral solar radiation and spectral albedo observed over a permafrost region of the Tanggula Range from 24 June to 16 October,2005,using the ratio of daily amount of global radiation to daily amount of extraterrestrial radiation,i.

根据青藏高原唐古拉山多年冻土区2005年6月24日~10月16日的总辐射、分光辐射和分光反照率观测资料,利用总辐射和大气层顶太阳辐射的比值——日有效透射率Teff,用聚类分析法将资料划分为晴天、多云和阴天三类天气,分析了该地区夏、秋季节总辐射、分光辐射比例和分光反照率的日变化和季节变化规律。
