奇怪的是当太阳黑子较多时，太阳能量的总体输出——太阳总辐照度(TSI)反而在一个较高的水平。

Paradoxically when there are most sunspots, overall solar output - called total solar irradiance (TSI) - is also at a high.

投射到大气顶部的太阳辐照度只有经向分布。

The irradiance of solar energy impinging on the top of the atmosphere has a meridional distribution.

利用LOWTRAN7计算了给定大气模式、辐射条件下的太阳直射辐照度、大气光谱透过率、大气上行路径辐亮度。

Direct solar irradiance, spectral transmission and atmospheric up well radiance under certain circumstance of atmosphere and radiation are also computed in virtue of software LOWTRAN7.
