Meteorological Analysis and Support for the Pacific Atmospheric Sulfur Experiment

在这个项目中，将利用现有的气象数据和分析、卫星图像和其他数据、来自NSF/NCAR C-130的数据以及追溯和气候学数据，调查太平洋大气硫实验的关键气象方面。这些方面包括对将在其中进行硫通量和收支观测的对流边界层结构的动力和热力学控制，控制赤道上升流和由此产生的引发DMS外流的初级生产力的流域范围到天气尺度的风分布，主导从无云到多云条件的大气波的结构和传播，以及南方涛动和厄尔尼诺的发生和表现。PI也将是PASE的任务气象学家，在实地活动期间为调查人员提供分析和预报支持。将组装气象图、卫星图像和其他所需产品，并通过互联网和/或传真发送到外地地点。实地活动结束后，将利用与上文列举的数据和技术平行的数据和技术，对观测区域进行全面的气象分析。此外，还将对圣诞岛附近先前硫磺预算研究期间的气象条件进行回顾研究。该项目的广泛影响包括支持一名在气象学和大气化学之间具有跨学科兴趣的研究生。还将在纳拉甘西特、罗德岛和基里蒂马蒂岛(圣诞岛)的中学开展外联工作。

In this project, the key meteorological aspects of the Pacific Atmospheric Sulfur Experiment (PASE) will be investigated, using available meteorological data and analyses, satellite images and other data, data from the NSF/NCAR C-130, and retrospective and climatological data. These aspects include dynamical and thermodynamic controls on the structure of the convective boundary layer in which the sulfur flux and budget observations will be made, the basin-wide to synoptic scale wind distributions that control Equatorial upwelling and the resultant primary productivity which initiates the efflux of DMS, the structure and propagation of atmospheric waves that dominate the progression from cloud-free to cloudy conditions, and the occurrence and manifestations of the Southern Oscillation and El Nino. The PI will also be the mission meteorologist for PASE, providing analysis and forecasting support to the investigators during the field campaign. Meteorological charts, satellite images, and other needed products will be assembled and sent to the field site via the internet and/or facsimile transmission. After the field campaign, a comprehensive meteorological analysis will be developed for the area of the observations, using data and techniques parallel to those enumerated above. Also, a retrospective study of meteorological conditions during prior sulfur budget studies near Christmas Island will be carried out.Broader impacts of this project include support for a graduate student with interdisciplinary interests at the boundary between meteorology and atmospheric chemistry. There will also be outreach efforts in secondary schools in Narragansett, Rhode Island and on the island of Kiritimati (Christmas Island).
