Navigating the New Arctic (NNA) is one of NSF's 10 Big Ideas. NNA projects address convergence scientific challenges in the rapidly changing Arctic. The Arctic research is needed to inform the economy, security and resilience of the Nation, the larger region and the globe. NNA empowers new research partnerships from local to international scales, diversifies, and the next generation of Arctic researchers, and integrates the co-production of knowledge. This award fulfills part of that aim. The cold and dark wintertime conditions of the Arctic lead to frequent poor air quality episodes linked to local emissions along with temperature inversions that trap pollutants in the areas where people live. Infrastructure planning such as energy generation and industrial activities along with residential choices of heating fuels such as wood, fuel oil or others are critical aspects of this problem. Residents spend most of their time indoors during wintertime, so most exposure to pollutants occurs indoors. From this background, fundamental knowledge gaps were identified in: outdoor/indoor air transport, indoor pollution sources such as leaky heating appliances, and chemical transformation of pollutants under these Arctic conditions. These gaps must be closed to understand the impacts of air pollution on Arctic communities and improve community health. Sustainably Navigating Arctic Pollution -- Through Engaging Communities (SNAP-TEC) focuses on improving understanding of wintertime Arctic outdoor and indoor air pollution. Discussions with community members will assist researchers in identifying local concerns regarding air quality, and in designing appropriate sustainable development frameworks, with the goal of improving air quality for Arctic peoples. To investigate wintertime Arctic air pollution issues at the intersection of the natural and built environments and social systems, SNAP-TEC uses a convergence approach that starts with a community engagement process to build a research and co-generation of knowledge program that has direct impacts on the community. This project has grown out of organizing efforts under the International Global Atmospheric Chemistry (IGAC) Project activity "Air Pollution in the Arctic: Climate, Environment and Societies" (PACES) and the Alaskan Layered Pollution and Chemical Analysis (ALPACA) project, which have documented knowledge gaps in this area. (See the ALPACA whitepaper, readily available online.) SNAP-TEC brings together a multi-disciplinary team to investigate this problem, with the center focus being a wintertime field campaign in Fairbanks, Alaska, where the scientific and social issues surrounding poor air quality can serve as a case study to inform practice and policy in similar cities, and villages across the broader Arctic region. The resulting knowledge of pollution sources and chemistry, housing and pollution control technology, and social aspects, can assist New Arctic communities to plan appropriate solutions that work for residents. Local and Indigenous peoples are most likely to be affected by Arctic development, therefore, the community engagement process will include local Fairbanks residents and Alaska Native community members. The project measures indoor and outdoor air quality using state-of-the art instrumentation to advance fundamental understanding of air pollution sources and chemical processes under cold and dark conditions, indoor/outdoor air exchange, and physicochemical changes to pollutants upon warming to indoor conditions, sulfur oxidation chemistry, and toxicity of air pollution. The field program is combined with community meetings, public participation in scientific data collection (a.k.a. citizen science, using inexpensive air-quality sensor monitoring), and a survey to assess public understanding of air quality, trust in science, perceived risk and uncertainty, and support for air quality policies. The SNAP-TEC research team involves a diverse group of natural and social scientists and engineers with extensive student involvement to address the problem. Through the international PACES organization, lessons learned from this investigation will be extended to an international pan-Arctic context through identification of fundamental processes and best practices, informing Arctic development and future studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

新北极航行（NNA）是NSF的十大创意之一。NNA项目解决快速变化的北极地区的趋同科学挑战。北极研究需要为国家、更大地区和地球仪的经济、安全和复原力提供信息。NNA授权从地方到国际规模的新的研究伙伴关系，多样化和下一代北极研究人员，并整合知识的共同生产。这个奖项实现了这个目标的一部分。北极寒冷黑暗的冬季条件导致空气质量频繁恶化，这与当地排放沿着气温逆温有关，使污染物滞留在人们居住的地区。基础设施规划，如能源生产和工业活动，沿着住宅选择取暖燃料，如木材，燃油或其他是这个问题的关键方面。居民在冬季大部分时间都在室内度过，因此大多数污染物暴露在室内。在这一背景下，确定了以下方面的基本知识差距：室外/室内空气传输、室内污染源，如泄漏的加热设备，以及在这些北极条件下污染物的化学转化。必须弥合这些差距，以了解空气污染对北极社区的影响，并改善社区健康。可持续地导航北极污染-通过参与社区（SNAP-TEC）的重点是提高冬季北极室外和室内空气污染的理解。与社区成员的讨论将有助于研究人员确定当地对空气质量的关切，并设计适当的可持续发展框架，以改善北极人民的空气质量。为了调查自然和建筑环境以及社会系统交叉点的冬季北极空气污染问题，SNAP-TEC采用了一种融合方法，从社区参与过程开始，建立一个对社区有直接影响的研究和知识计划的共同生成。该项目是在国际全球大气化学项目活动“北极空气污染：气候、环境和社会”和阿拉斯加分层污染和化学分析项目下组织努力的结果，这些项目记录了这一领域的知识差距。(See ALPACA白皮书，可在线获取。）SNAP-TEC汇集了一个多学科的团队来调查这个问题，中心重点是在阿拉斯加州的费尔班克斯进行冬季实地活动，围绕空气质量差的科学和社会问题可以作为案例研究，为类似城市的实践和政策提供信息，以及整个北极地区的村庄。由此产生的污染源和化学，住房和污染控制技术以及社会方面的知识，可以帮助新北极社区规划适合居民的适当解决方案。当地和原住民最有可能受到北极开发的影响，因此，社区参与过程将包括当地的费尔班克斯居民和阿拉斯加原住民社区成员。该项目使用最先进的仪器测量室内和室外空气质量，以促进对寒冷和黑暗条件下空气污染源和化学过程的基本了解，室内/室外空气交换，以及在室内条件下变暖时污染物的物理化学变化，硫氧化化学和空气污染的毒性。实地项目与社区会议、公众参与科学数据收集（又名公民科学，使用廉价的空气质量传感器监测），以及一项调查，以评估公众对空气质量的了解、对科学的信任、感知的风险和不确定性，以及对空气质量政策的支持。SNAP-TEC的研究团队包括一个由自然和社会科学家和工程师组成的多元化团队，学生广泛参与解决这个问题。通过国际PACES组织，从这次调查中吸取的经验教训将通过确定基本过程和最佳实践扩展到国际泛北极背景，为北极发展和未来研究提供信息。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
