求助：一个句子结构分析

求助以下句子中成分分析：

radiatiersonName>onersonName> that would otherwise be transmitted back into space是其前面的infrared emissiersonName>onersonName>s的同位语。

那么，infrared emissiersonName>onersonName>s radiated from the Earth's surface 又作前面句子的什么成份呢？也做同位语？

谢谢

Although these molecules allow radiatiersonName>onersonName>   at visible wavelengths，    where most of the energy of sunlight    is cersonName>onersonName>centrated， to pass through， they absorb some of the longer-wavelength，     infrared emissions radiated from the Earth's surface，  radiation that    would　otherwise be transmitted back into space.
