Abstract ATM -9727329 Tsonis, Anastasios University of Wisconsin TITLE: Improving the Information on Precipitation Over Oceans and Studying its Temporal and Spatial Variability One of the most comprehensive climate data sets is the University of Wisconsin, Milwaukee/ COADS (UWM/COADS) analysis set. Precipitation over the oceans is probably the least reliable quantity in the data set.. This proposal suggests a way to correct for this satellite - derived rainfall over the oceanic regions by multivariate models that include other quantities that are more reliable and are directly observed. The proposal intends to investigate the temporal and spatial variability of the global precipitation field over selected oceanic regions as well as over the globe utilizing such corrected precipitation data. The data produced by the proposal will be of great value for climate studies and research.

摘要 ATM -9727329 Tsonis, Anastasios 威斯康星大学 标题：改进海洋降水信息并研究其时空变化 最全面的气候数据集之一是威斯康星大学密尔沃基分校/COADS (UWM/COADS) 分析集。海洋上的降水量可能是数据集中最不可靠的量。该提案提出了一种通过多元模型来校正该卫星得出的海洋区域降水量的方法，其中包括其他更可靠且直接观测到的量。该提案旨在利用此类修正的降水数据来研究选定海洋区域以及全球范围内全球降水场的时间和空间变化。 该提案产生的数据对于气候研究具有重要价值。
