The HIAPER Pole-to-Pole Observations (HIPPO) program will provide global, meridional coverage of important carbon cycle and green house gases via vertical profiles throughout the depth of the troposphere. This will enable closure and inversion of global budgets of these critical gases (such as carbon dioxide, carbon monoxide, and methane), as well as related long-lived tracers and their ratios. This program will provide the first comprehensive, global survey of atmospheric trace gases, covering the full troposphere in all seasons and multiple years. The Microwave Temperature Profiler (MTP) can make an important contribution to HIPPO because it provides meteorological context for the other measurements by identifying the height of the tropopause.These measurements will be used to understand tracer/tropopause conundrums. An added benefit of the MTP measurements is that they can also be used identify isentropes - the streamlines on which air parcels flow. (This is done by converting the temperature profile to a potential temperature profile, and then identifying on successive profiles the height of a specific potential temperature value.) This allows the presence of atmospheric waves to be identified, which could further facilitate the interpretation of other measurements. Finally, since oceanic regions are notoriously radiosonde sparse, the MTP temperature profiles will fill this void and allow better initialization of atmospheric chemistry models.

Hiaper Pole-to-Pole观测（HIPPO）计划将通过整个对流层深度通过垂直剖面对重要的碳循环和温室气体进行全球子午线覆盖范围。 这将使这些关键气体（例如二氧化碳，一氧化碳和甲烷）以及相关的长期示踪剂及其比率的全球预算关闭和反转。 该计划将对大气痕量气体进行首次全面的全球调查，涵盖所有季节和多年的整个对流层。 微波温度探测器（MTP）可以对河马做出重要贡献，因为它通过识别对流层顶的高度为其他测量提供了气象环境。这些测量将用于了解示踪剂/对流层层状果子。 MTP测量值的额外好处是，它们也可以被使用识别等entropes - 空气包裹流的流线。 （这是通过将温度曲线转换为潜在温度曲线的，然后在连续的特征上识别特定电势温度值的高度来完成。）这允许确定大气波的存在，这可以进一步促进对其他测量的解释。 最后，由于众所周知，海洋区域是辐射稀疏的，因此MTP温度曲线将填充该空隙，并可以更好地初始化大气化学模型。
