This award, under the auspices of the Small Grants for Exploratory Research (SGER) program, provides funds to develop a North American Drought Atlas, on CD-ROM, based on tree-ring reconstructions of the summer (June-July-August) Palmer Drought Severity Index (PDSI). These reconstructions will be on a 297-point 2.5x2.5 degrees regular grid and cover the past 600 years. The tree-ring data was collected over a period of years with prior funding from the Paleoclimate Program at the National Science Foundation.The atlas will provide yearly PDSI reconstructions overlain on a map of North America dating from the year AD 1400 (or earlier where possible) through the year 1990 that can be viewed individually and in movie format. The PDSI maps will provide a graphic picture of dynamic drought and wetness across the North America continent. The CD-ROM atlas will allow individual reconstructions to be displayed as time series for any given grid point in North America. The data used to develop the PDSI temporal and spatial reconstructions will also be provided on the CD-ROM, along with full documentation. This will allow users to examine the detailed history of drought and wetness for any location and use the data for further analysis. Once completed, the CD-ROM may be run on a laptop computer and also accessed from NOAA's National Geophysical Data Center (NGDC) website. The project cost-effectively leverages previous investments of public funds for paleoclimate science research to achieve a potentially significant payoff for the international community of paleoclimate science researchers, and the general public, through a synthesis of paleoclimatic data and analysis.

在探索性研究小额赠款方案的赞助下，该奖项提供资金，以根据夏季（6月至7月至8月）帕尔默干旱严重程度指数（PDSI）的树木年轮重建制作一张光盘形式的《北美干旱地图集》。 这些重建将在297点2.5x2.5度的规则网格上进行，覆盖过去600年。 这些树木年轮数据是在美国国家科学基金会古气候计划的资助下收集的。该地图集将提供从公元1400年（或更早的时候）到1990年的北美地图上覆盖的每年PDSI重建图，可以单独观看或以电影格式观看。 PDSI地图将提供整个北美大陆动态干旱和潮湿的图形。光盘地图集将允许将北美任何给定网格点的单个重建显示为时间序列。 用于开发PDSI时空重建的数据也将以光盘形式提供，沿着完整的文件。 这将使用户能够检查任何地点的干旱和潮湿的详细历史，并将数据用于进一步分析。 一旦完成，光盘可在膝上型计算机上运行，也可从NOAA的国家地球物理数据中心网站访问。 该项目以成本效益高的方式利用公共基金先前对古气候科学研究的投资，通过综合古气候数据和分析，为国际古气候科学研究人员和公众带来潜在的重大回报。
