Aerosol Chemistry, Optics and Micro-Physics over the Tropical North Atlantic and Caribbean

该计划的总体目标是通过检查热带和亚热带北大西洋和加勒比海主要气溶胶种类的化学，物理和光学特性，以更好地了解气溶胶颗粒如何影响气候和气候变化，以了解导致这些特性的任何显着时间或空间变化的过程。 将在三个地面站对气溶胶特性进行连续测量：加那利群岛特内里费岛的伊扎纳;巴巴多斯的拉格德角;和佛罗里达的迈阿密。 这些测量结果将成为长期数据库的一部分，该数据库始于1965年在巴巴多斯Ragged Point建立一个大气采样点，并通过大气/海洋化学实验继续进行，热带北大西洋和加勒比地区特别重要和有趣，因为热带海洋被认为对天气和气候有重大影响，因为这些海洋地区的大气层比其他任何地方都更容易受到空气中颗粒物的影响，特别是矿物尘埃。 在夏季的几个月里，来自北非和南欧的污染物与矿物粉尘一起运输。 在冬季，来自非洲较南部地区的矿物粉尘不太频繁地通过大气层输送，通常与生物质燃烧产品一起输送。

The overall objective of this program is to gain a better understanding of how aerosol particles impact climate and climate change by examining the chemical, physical, and optical properties of the major aerosol species over the tropical and subtropical North Atlantic Ocean and Caribbean to understand the processes that cause any significant temporal or spatial variations in those properties. Continuous measurements of aerosol properties will be made at three ground stations: Izana, Tenerife, Canary Islands; Ragged Point, Barbados; and Miami, Florida. These measurements will become part of a long-term database that began in 1965 with the establishment of an atmospheric sampling site at Ragged Point, Barbados and continued through the Atmosphere/Ocean Chemistry Experiment (AEROCE).The tropical North Atlantic and Caribbean are particularly important and interesting because tropical oceans are thought to have a significant impact on weather and climate, and because these ocean regions underlay an atmosphere more impacted by airborne particles, especially mineral dust, than any other. During summer months, pollutants from North Africa and southern Europe are transported with mineral dust. During the winter, less frequent episodic transport of mineral dust from more southern regions in Africa are carried through the atmosphere often with biomass burning products.
