Regional Cooperative Activities to Support Global Change Research in IAI Countries - Jamaica

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。这一降水数据集目前由月平均站数据组成，由气候预测中心CAMS站1851年1月至1994年9月的降水数据和CDIAC全球历史气候学网络数据库1832年10月至1990年10月的降水数据汇编而成，不考虑重复数据。降水数据和其他数据将通过使用NCEP和ECMWF再分析数据以及TRMM数据(如果有)加以扩充。将增加CDIAC月气温、海平面气压和站气压数据。还将利用哈德利中心提供的GISST 2.3数据集纳入SST数据。还将纳入世界和加勒比相关机构，包括加勒比气象研究所(CMI)提供的其他数据集，包括高空空气数据和土壤湿度，这些数据已经过质量控制检查。合并后的数据集将使用Grads R40格式的面积加权平均值进行网格化。这个数据集的初步版本已经用于分析，但完整版本将通过将其与谢阿金数据进行比较来检查其在海洋上的有效性，谢-阿金数据的时间跨度较短(1997年以后)，但包括海洋观测数据。卫星图像和数据将从波多黎各大学马亚圭斯分校(UPRM)获得。区域气候模式MM5将与马里兰大学气象系合作，用于研究加勒比地区的气候变异性。西印度群岛大学为此设立了一个为期两年的气候建模职位，目前在马里兰大学完成博士学位的一名学生将在两年结束时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，以便在美洲，包括美国和加拿大的研究小组成员之间交换由IAI赞助的研究所产生的全球变化数据。该项目将特别允许美国研究人员访问以前无法访问的来自美洲其他地区的数据集。国家科学基金会是指定的美国政府机构，在IAI内履行美国的责任。

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.
