SOLVE I ER-2 Analysis Model Data

SOLVE1_Analysis_ER2_Data contains modeled trajectories and meteorological data along the flight path for the ER-2 aircraft collected during the SAGE III Ozone Loss and Validation Experiment (SOLVE). Data collection for this product is complete.

The SOLVE campaign was a NASA multi-program effort of the Upper Atmosphere Research Program (UARP), Atmospheric Effects of Aviation Project (AEAP), Atmospheric Chemistry Modeling and Analysis Program (ACMAP) and Earth Observing System (EOS) of NASA’s Earth Science Enterprise (ESE). SOLVE’s primary objective was for calibrating and validating the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite measurements, while examining the processes that controlled ozone levels at a mid- to high-latitude range. The major goal of SAGE III was to quantitatively assess ozone loss at high latitudes. SOLVE was a two-phase experiment, the first phase, SOLVE, occurred during the fall of 1999 through the spring of 2000. The second phase, SOLVE II, occurred during the winter of 2003.

SOLVE took place in the Arctic high-latitude region during the winter. The polar ozone depletion processes cause by human-produced chlorine and bromine are most active in mid-to-late winter and early spring in the high Arctic. In order to conduct this validation experiment, NASA deployed the NASA ER-2 aircraft and NASA DC-8 aircraft. The ER-2 measured a variety of atmospheric data, including ozone (O3), H2O, CO2, ClONO2, HCl, ClO/BrO, and Cl2O2. The DC-8 aircraft measured ozone, ClO/BrO, and aerosol, among other atmospheric data. SOLVE also utilized balloon platforms, ground-based instruments, and collaborations with the German Aerospace Center’s (DLR) FALCON aircraft equipped with the OLEX Lidar to achieve the mission objectives. Overall, the campaign had 28 flights, with SOLVE featuring 17 total flights among the different aircrafts and SOLVE II featuring 11 flights.

SOLVE1_Analysis_ER2_Data 为SAGE III臭氧损耗与验证实验（SOLVE）期间收集的ER-2飞机航迹沿线模拟轨迹与气象数据集，该产品的数据采集工作已全部完成。

SOLVE任务是美国国家航空航天局（National Aeronautics and Space Administration, NASA）地球科学企业（Earth Science Enterprise, ESE）下属高层大气研究计划（Upper Atmosphere Research Program, UARP）、航空项目大气影响计划（Atmospheric Effects of Aviation Project, AEAP）、大气化学建模与分析计划（Atmospheric Chemistry Modeling and Analysis Program, ACMAP）以及地球观测系统（Earth Observing System, EOS）联合开展的多项目研究。SOLVE的核心目标是对平流层气溶胶与气体探测（Stratospheric Aerosol and Gas Experiment, SAGE）III卫星的测量结果进行校准与验证，同时探究中高纬度区域臭氧水平的调控机制。SAGE III的主要目标是定量评估高纬度地区的臭氧损耗情况。SOLVE实验分为两个阶段：第一阶段SOLVE于1999年秋季至2000年春季开展，第二阶段SOLVE II则于2003年冬季实施。

SOLVE实验在北极高纬度地区的冬季开展。由人类活动产生的氯、溴所引发的极地臭氧损耗过程，在北极高纬度地区的隆冬至晚冬及早春时段最为活跃。为完成本次验证实验，NASA部署了ER-2与DC-8两款科研飞机：ER-2可采集多种大气数据，包括臭氧（O₃）、水汽（H₂O）、二氧化碳（CO₂）、硝酸氯（ClONO₂）、氯化氢（HCl）、氯氧/溴氧（ClO/BrO）以及二氯二氧化物（Cl₂O₂）等；DC-8则可采集臭氧、ClO/BrO、气溶胶等多种大气数据。此外，SOLVE任务还依托气球平台、地基观测仪器，并与搭载OLEX激光雷达的德国航空航天中心（Deutsches Zentrum für Luft- und Raumfahrt, DLR）FALCON飞机开展合作，以达成任务目标。本次任务总计执行28架次飞行：SOLVE阶段各机型累计执行17架次，SOLVE II阶段则执行11架次。
