This award will enable preparation for the proposed HIAPER Pole-to-Pole Observations (HIPPO) program. HIPPO will provide the first global-scale ("pole-to-pole") survey of atmospheric tracers through the annual cycle, providing cross sections from the surface to the tropopause. It is planned to install instruments on the NSF/NCAR G-V aircraft (HIAPER) to measure a comprehensive suite of tracers, including carbon dioxide (CO2), oxygen/nitrogen ratio (O2:N2), carbon dioxide isotopomers (13CO2:12CO2), methane (CH4), carbon monoxide (CO), nitrous oxide (N2O), molecular hydrogen (H2), sulfur hexafluoride (SF6), carbonyl sulfide (COS), chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs), and selected hydrocarbons. HIPPO will transect the mid-Pacific ocean and return over North and South America. The scientific questions motivating HIPPO focus on understanding the global carbon cycle, on defining large-scale rates of tracer transport in the troposphere and in the tropical tropopause layer, and on understanding tracer sources and sinks globally. HIPPO is intended to provide publicly available global data sets for a large suite of atmospheric tracers. It is planned to compare these data to the output of models used to assess the global distribution of sources and sinks of CO2. Additional modelers will be engaged to stimulate creative and effective application of these data.

该奖项将为拟议的 HIAPER 极地观测 (HIPPO) 计划做好准备。 HIPPO 将在年度周期内提供首次全球规模（“极地”）大气示踪剂调查，提供从地表到对流层顶的横截面。计划在 NSF/NCAR G-V 飞机 (HIAPER) 上安装仪器来测量全套示踪剂，包括二氧化碳 (CO2)、氧/氮比 (O2:N2)、二氧化碳同位素 (13CO2:12CO2)、甲烷 (CH4)、一氧化碳 (CO)、一氧化二氮 (N2O)、分子氢 (H2)、六氟化硫 (SF6)、硫化羰(COS)、氯氟碳化合物 (CFC)、氢氟碳化合物 (HCFC) 和特定碳氢化合物。 HIPPO 将横穿太平洋中部并飞越北美和南美返回。推动 HIPPO 的科学问题侧重于了解全球碳循环、定义对流层和热带对流层顶层示踪剂的大规模传输速率以及了解全球示踪剂源和汇。 HIPPO 旨在为大量大气示踪剂提供公开的全球数据集。计划将这些数据与用于评估二氧化碳源和汇的全球分布的模型的输出进行比较。将聘请更多建模人员来激发这些数据的创造性和有效应用。
