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.

表征温室气体增加和分布的需求是大气组成和气候群落的一阶科学目标。 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）。 这套由80 n至70 s制成的化学测量套件，并在大约六个每月的间隔内重复，将提供一个独特而确定的数据集，用于碳循环气体的反转和其他全球建模分析。碳循环气体的渐变梯度在半球浓度的温室气体中至关重要，这对于我们预测了carbone sissions of Carbon osissions of Carbon osissions of Carbon siils sissions of carbon osiss osiss osiss osiss osiss osiss osiss osiss osiss of carbon carboun siils imess of carboun sims imess s。 以前用于推断二氧化碳表面通量，源和水槽的化学转运模型研究通常被限制在使用边界层CO2浓度上。 因此，现场实验将利用使用Hiaper G-V飞机平台提供的大气科学界新近可用的变革性能力。这项工作得到了地球系统招标的NSF碳和水，这是一个跨学科的资金资金机会。
