项目摘要
This project will develop observation-based metrics for evaluating global atmospheric chemistry models. This suite of metrics will assist with climate model development and planning for the next chemistry Model Intercomparison Project (MIP) for the 7th IPCC assessment. This effort will document the development and improvements occurring in next-generation models and the traceability of confidence in policy-relevant model projections. A new or revised set of metrics focused on gas-phase chemistry will be developed involving high-order metrics (e.g., reaction rates, budgets, statistics, covariance of species) and/or relationships (e.g., budgets vs. perturbations, seasonal/interannual patterns in transport). Chemical transport models (CTM) at the University of California at Irvine and MIP archives will be used to draft the metrics. Scientific issues to be addressed include: (1) heterogeneity in chemical composition; (2) chemical budgets of tropospheric O3 and CH4; (3) CH4 chemistry feedback and O3 sensitivities; (4) tropospheric humidity, an emergent constraint; (5) N2O from the stratosphere to the surface; (6) stratospheric column ozone; (7) tropospheric column ozone and air mass; (8) photolysis rates and emergent constraints; and (9) surface O3, an air quality metric.A graduate student will participate in the design, testing, and documentation of the metrics.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.
该项目将为评估全球大气化学模型制定基于观测的衡量标准。这套指标将有助于气候模型的开发和规划下一个化学模型比较项目(MIP)的IPCC第七次评估。这项工作将记录下一代模型的发展和改进,以及对政策相关模型预测的信心的可追溯性。将开发一组新的或修订的侧重于气相化学的度量,涉及高阶度量(例如,反应速率、预算、统计、物种的协方差)和/或关系(例如,预算与扰动、运输的季节/年际模式)。加州大学欧文分校的化学传输模型(CTM)和MIP档案将用于起草指标。需要解决的科学问题包括:(1)化学成分的不均匀性;(2)对流层O3和CH 4的化学收支;(3)CH 4化学反馈和O3敏感性;(4)对流层湿度-一种紧急制约因素;(5)从平流层到地面的N2 O;(6)平流层臭氧柱;(7)对流层臭氧柱和空气质量;(8)光解率和紧急限制;(9)表面O3,一种空气质量指标。一名研究生将参与指标的设计、测试和记录。该奖项反映了NSF的法定使命,并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,被认为值得支持。
