This project will support several areas of global change research in the Caribbean. An existing precipitation data base for the Caribbean will be expanded. This precipitation data set currently consists of monthly average station data, and was compiled from the Climate Prediction Center CAMS station precipitation data for January 1851 through September 1994 and CDIAC Global Historical Climatology Network data base for precipitation for October 1832 through October 1990, with duplicate data ignored. Precipitation data and other data will be augmented by the use of NCEP and ECMWF re-analysis data and TRMM data if available. CDIAC monthly temperature, sea level pressure and station pressure data will be added. SST data will also be incorporated by using the GISST 2.3 data set from the Hadley Centre. Other data sets, including upper air data and soil moisture, from relevant world-wide and Caribbean institutes, including the Caribbean Meteorological Institute (CMI), which have been checked for quality control will also be incorporated. The combined data set will be gridded using an area weighting average in the GrADS R40 format. A preliminary version of this data set has already been used for analyses, but the full version will be checked for validity over the ocean by comparing it with the Xie-Arkin data which has a shorter time span (1997 onward), but includes observed data over the ocean. Satellite imagery and data will be obtained from the University of Puerto Rico, Mayaguez (UPRM). The regional climate model MM5, in collaboration with the Department of Meteorology, University of Maryland, will be used to study climate variability in the Caribbean. The University of the West Indies has created a 2 year post in Climate Modeling for this purpose, and a student presently completing his Ph.D. at the University of Maryland will return to continue the work of the climate modeling at the end of 2 years. The project will provide part of the backbone for a data and information system for the exchange of global change data resulting from IAI-sponsored research between members of research teams in the Americas, including the USA and Canada. This project will specifically give US researchers access to data sets from the rest of the Americas that have previously been inaccessible. The National Science Foundation is the designated U.S. Government agency to carry out U.S. responsibilities within the IAI.

该项目将支持加勒比地区全球变化研究的几个领域。将扩大加勒比地区现有的降水数据库。该降水资料集目前由月平均台站资料组成，由气候预测中心CAMS台站1851年1月至1994年9月的降水资料和CDIAC全球历史气候网1832年10月至1990年10月的降水资料汇编而成，忽略重复资料。降水数据和其他数据将通过使用NCEP和ECMWF再分析数据和TRMM数据进行扩充。将增加CDIAC月温度、海平面压力和站点压力数据。海温数据也将通过使用哈德利中心的GISST 2.3数据集纳入。来自包括加勒比气象研究所（CMI）在内的有关世界和加勒比研究所的其他数据集，包括高空数据和土壤湿度，也将被纳入质量控制检查范围。合并后的数据集将使用梯度R40格式的面积加权平均值进行网格化。该数据集的初步版本已经用于分析，但完整版本将通过与Xie-Arkin数据进行比较来检查其在海洋上的有效性，该数据具有较短的时间跨度（1997年以后），但包括在海洋上的观测数据。卫星图像和数据将从波多黎各马亚圭斯大学（UPRM）获得。与马里兰大学气象系合作的区域气候模式MM5将用于研究加勒比地区的气候变率。西印度群岛大学为此设立了一个为期2年的气候建模岗位，目前正在马里兰大学攻读博士学位的一名学生将在2年结束后返回继续气候建模工作。该项目将为数据和信息系统提供部分骨干，用于在美洲（包括美国和加拿大）的研究小组成员之间交换由iai赞助的研究产生的全球变化数据。该项目将特别为美国研究人员提供以前无法访问的美洲其他地区的数据集。美国国家科学基金会是美国政府指定的机构，负责履行美国在IAI中的职责。
