The Indian Ocean Experiment (INDOEX), a multidisciplinary field experiment was conducted from January to March, 1999 over the Indian Ocean. A follow-up requirement of such a multi-platform experiment is to develop an integrated database and coherent analysis of various observations that can be utilized by different participating groups and future investigators. The main objective of this project is to integrate and analyze the lower troposphere meteorological observations taken from different platforms such as ships, aircraft, satellites and land-based stations and investigate the role of land-ocean-atmosphere interactions on the atmospheric transport of aerosols and gases.These observations will be used to: 1) evaluate and provide a consistent data set of boundary layer/meteorological observations, and 2) develop a detailed analysis of the role of aerosol-rich land plume and its interaction with the Marine Boundary Layer during INDOEX. This study will have a positive impact on the analysis of the various components of INDOEX observations by different groups, and will add to our knowledge of the influence of man-made atmospheric chemical constituents on the climate of South Asia and the Indian Ocean.

1999年1月至3月在印度洋上空进行了印度洋实验，这是一项多学科实地实验。 这种多平台试验的一项后续要求是建立一个综合数据库，并对各种观察结果进行连贯一致的分析，供不同的参与团体和今后的调查人员使用。 该项目的主要目标是综合和分析从船舶、飞机、卫星和陆基台站等不同平台获取的对流层低层气象观测数据，并研究陆地-海洋-大气相互作用对气溶胶和气体大气输送的作用。这些观测数据将用于：1）评价并提供一套一致的边界层/气象观测数据; 2）详细分析INDOEX期间富含气溶胶的陆地羽流的作用及其与海洋边界层的相互作用。 这项研究将对不同小组分析INDOEX观测的各种组成部分产生积极影响，并将增加我们对人为大气化学成分对南亚和印度洋气候影响的了解。
