The need to characterize the increase and distribution of greenhouse gases is a first order scientific goal of the atmospheric composition and climate communities. The HIAPER Pole-to-Pole Observations (HIPPO) program will provide global, meridional coverage, via vertical profiles throughout the depth of the troposphere enabling closure and inversion of global budgets of critical greenhouse gases (e.g. carbon dioxide, CO2; carbon monoxide, CO; and methane, CH4), and related long-lived tracers and ratios (e.g. the oxygen/nitrogen ratio, O2/N2). This suite of chemical measurements, made from 80 N to 70 S, and repeated over approximately six monthly intervals, will provide a unique and definitive data set, to be used in inversion and other global modeling analyses of carbon cycle gases.Observed gradients in the hemispheric concentrations of greenhouse gases are critical to our ability to predict the fate of anthropogenic emissions of carbon gases. Previous chemical transport modeling studies used to infer CO2 surface fluxes, sources and sinks have been generally constrained to using boundary layer CO2 concentrations. The field experiments will thus take advantage of transformative capabilities newly available to the atmospheric science community provided by the use of the HIAPER G-V aircraft platform.This work is supported under the NSF Carbon and Water in the Earth System solicitation, an interdisciplinary funding opportunity from the Directorate of Geosciences.

描述温室气体的增加和分布特征是大气成分和气候群体的首要科学目标。 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全球经向覆盖，从而实现关键温室气体（例如二氧化碳、CO2、一氧化碳、CO 和甲烷、CH4）以及相关长寿命示踪剂和比率（例如氧/氮比、 氧气/氮气）。 这套化学测量在 80 N 至 70 S 范围内进行，并在大约六个月的时间间隔内重复进行，将提供独特且明确的数据集，用于碳循环气体的反演和其他全球建模分析。观测到的半球温室气体浓度梯度对于我们预测人为碳气体排放命运的能力至关重要。 以前用于推断二氧化碳表面通量、源和汇的化学输运模型研究通常仅限于使用边界层二氧化碳浓度。 因此，现场实验将利用 HIAPER G-V 飞机平台为大气科学界提供的新的变革能力。这项工作得到了 NSF 地球系统碳和水征集的支持，这是一个来自地球科学局的跨学科资助机会。
