High-resolution IR remote-sensing measurements from space by means of a nadir-viewing geometry are particularly suited to the detection of trace gases and yield high temporal and horizontal resolutions on a global scale. To identify the potential of such a technique, an extensive feasibility study has been performed. The column amount of some trace gases, namely H(2)O, CH(4), N(2)O, CO, and O(3), may be determined with accuracies of approximately 10%. In addition, some information on the vertical distribution of these species is also possible. Concerning CFC-12, an accuracy of 10%-20% may be expected. Furthermore, it is believed that column amounts can be derived with an accuracy of 20% for HNO(3), and 50% for species like NO(2), OCS, and CFC-11.
通过天底观测几何构型从太空进行高分辨率红外遥感测量特别适合于痕量气体的探测，并能在全球范围内提供高时间分辨率和水平分辨率。为了确定这种技术的潜力，已经进行了广泛的可行性研究。一些痕量气体的柱总量，即H₂O、CH₄、N₂O、CO和O₃，可以以大约10%的精度测定。此外，关于这些物种垂直分布的一些信息也是可能的。对于CFC - 12，预计精度为10% - 20%。此外，据信对于HNO₃，柱总量可以以20%的精度推导出来，对于NO₂、OCS和CFC - 11等物种，精度为50%。
