一旦天文学家知道一个太阳系外行星的大小，并对它的位置了解的足够精确的话，他们就可以求助于气候模型师，他们可以创造虚拟的大气，并且观察它是如何运转的。
Once astronomers know an exoplanet's size and location with reasonable accuracy, they can turn it over to climate modelers who can create a virtual atmosphere and see how it might behave.
而多数行星模型均假设它们和我们太阳系的类地行星相似，即在大气中碳含量是氧含量的一半左右。
Most models of planets assume that they are similar to the terrestrial planets in our own Solar System, with about half as much carbon as oxygen in the atmosphere.
模型成功重现了在太阳辐射变化时，科学家已经在高层大气观测到的状况。
