SGER: Microwave Temperature Profiler (MTP) Support for HIAPER Pole-to-Pole Observations (HIPPO)

HIAPER极地观测(HIPPO)计划将通过整个对流层深度的垂直剖面，提供重要的碳循环和温室气体的全球经向覆盖。这将使这些关键气体(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得以关闭和倒置。该计划将提供第一次全面的全球大气痕量气体调查，覆盖所有季节和多年的整个对流层。微波温度廓线仪(MTP)可以对河马做出重要贡献，因为它通过识别对流层高度为其他测量提供了气象背景。这些测量将被用来理解示踪剂/对流层顶难题。MTP测量的另一个好处是，它们还可以用来识别等熵--空气包在其上流动的流线。(这是通过将温度分布转换为潜在温度分布，然后在连续的分布上识别特定潜在温度值的高度来实现的。)这使得能够识别大气波的存在，这可以进一步便利对其他测量结果的解释。最后，由于海洋区域是出了名的无线电探空稀疏，MTP温度分布将填补这一空白，并允许更好地初始化大气化学模型。

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.
