We estimated the Korea Shortwave Radiation Budget (KSRB) providing new insights into the Korea climate system. Monthly averaged clear-sky, overcast-sky, and all-sky flux measurements with cloud amounts from 2000 to 2015 were used to assess the impacts of cloud on the KSRB. A deterministic model for shortwave radiation transfer was utilized with climatological data to compute the monthly mean of KSRB at the surface, in the atmosphere and at the top-of-atmosphere (TOA). For 10 Korean stations ranging from 33.5°N to 37.7°N, the daily mean of incoming solar flux at TOA is 345.2 Wm⁻². 45.5% of that is transmitted to the surface, 25.0% is absorbed in the atmosphere and 29.5% is reflected directly back to space by the cloud, atmosphere and ground surface under all-sky conditions. Under clear- and overcast-sky conditions, 63.2% and 24.9% are transmitted to the surface, 17.8% and 37.1% are absorbed in the atmosphere, whereas 19.0% and 38.0% are reflected to space, respectively, showing a remarkably invariant value with respect to locations. Clouds in all- (or overcast-) sky atmosphere diminish surface solar irradiances (SSI) from 218.1 Wm⁻² to 156.9 Wm⁻² (or 85.8 Wm⁻²) and enhance atmospheric absorptions (AA) from 61.5 Wm⁻² to 86.3 Wm⁻² (or 128.2 Wm⁻²). Clouds also enhance the reflected irradiances (RI) at the TOA from 65.6 Wm⁻² to 102.0 Wm⁻² (or 131.2 Wm⁻²) for all- (or overcast-) skies. As a result, the all- (or overcast-) sky shortwave (SW) cloud forcing (CF) is −61.2 Wm⁻² (or −132.3 Wm⁻²) at the surface, AA is 24.8 Wm⁻² (or 66.7 Wm⁻²) in the atmosphere and RI is 36.4 Wm⁻² (or 65.6 Wm⁻²) at the TOA, respectively. Consequently, it is found that the values for SW-CF at the surface is 1.7 times and 2.0 times greater than that at the TOA in the KSRB under all- and overcast-sky conditions, respectively. We have also compared the KSRB with the global shortwave radiation budget (GSRB) and discussed on the shortwave radiation budget.

我们估算了《韩国短波辐射预算》（KSRB），它为韩国气候系统提供了新的见解。使用2000年至2015年的月平均晴空，阴天和全天通量测量值以及云量来评估云对KSRB的影响。利用短波辐射的确定性模型和气候数据来计算地表，大气和最高大气层（TOA）中KSRB的月平均值。对于从33.5°N到37.7°N的10个韩国气象站，TOA处入射太阳通量的日均值为345.2 Wm ^-2。其中有45.5％被传输到地表，25.0％被大气吸收，而29.5％在全天候条件下被云，大气和地面直接反射回太空。在晴空条件下，大气中有63.2％和24.9％被传输到大气中，大气中有17.8％和37.1％被吸收，而在太空中则被反射了19.0％和38.0％，显示出明显的不变值。关于位置。全天（或阴天）大气中的云将表面太阳辐照度（SSI）从218.1 Wm ^-2减少到156.9 Wm ^-2（或85.8 Wm ^-2），并将大气吸收（AA）从61.5 Wm ^-2增加到86.3 Wm ⁻²（或128.2 Wm ⁻²）。对于所有（或阴天）天空，云层还将TOA处的反射辐照度（RI）从65.6 Wm ^-2增强到102.0 Wm ^-2（或131.2 Wm ^-2）。结果，在表面的全（或阴）天短波（SW）云强迫（CF）为-61.2 Wm ^-2（或-132.3 Wm ^-2），AA为24.8 Wm ^-2（或66.7 Wm）^-2），RI为36.4 Wm ^-2（或65.6 Wm ^-2）。因此，发现在全天空和阴天条件下，表面的SW-CF值分别比KSRB中TOA的值大1.7倍和2.0倍。我们还将KSRB与全球短波辐射预算（GSRB）进行了比较，并讨论了短波辐射预算。
