很难获得跨越晚更新世和全新世的高时间分辨率的全球规模气候变化预测。这限制了我们辨别气候波动如何影响物种的范围动态和灭绝过程、生态群落的转变和遗传多样性的变化的能力。PaleoView是一种新的免费软件工具，它提供了一种全面但易于使用的方式来生成和查看时间和空间分辨率的古气候数据，适合于检测自上一次冰盛期以来主要气候变化的生物响应。区域到全球尺度的温度、降水、湿度和平均海平面气压的模拟可以从PaleoView生成网格或时间序列数据，在过去21 000年中的任何时期，时间间隔短至10年。它们可以使用内置的地理用户界面查看，也可以另存为数据文件。模拟的气候重建是基于社区气候系统模式版本的每日模拟输出。3(CCSM3)。这一全球大气-海洋-海冰-陆地耦合环流模式准确地再现了与最近一次冰川消融事件相关的主要气候特征，并以经过验证的后播技术预测了当今气候条件的模式。通过提供一个以高时间分辨率随时获取气候重建的门户，PaleoView可以帮助更好地确定过去气候波动对生物和遗传多样性的宏观生态模式的影响。
It has been difficult to access projections of global-scale climate change with high temporal resolution spaning the late Pleistocene and Holocene. This has limited our ability to discern how climate fluctuations have affected species' range dynamics and extinction processes, turn-over in ecological communities and changes in genetic diversity. PaleoView is a new freeware tool, which provides a comprehensive but easy-to-use way to generate and view paleoclimate data at temporal and spatial resolutions suitable for detecting biotic responses to major climate shifts since the last glacial maximum. Regional to global scale simulations of temperature, precipitation, humidity and mean sea level pressure can be generated from PaleoView as gridded or time series data at time intervals as short as a decade for any period during the last 21 000 yr. They can be viewed using a built-in geographical user interface or saved as data files. Modelled climate reconstructions are based on daily simulation output from the Community Climate System Model ver. 3 (CCSM3). This global coupled atmosphere-ocean-sea ice-land general circulation model accurately reproduces major climatic features associated with the most recent deglaciation event, and predicts present-day patterns of climate conditions with verified hindcast skill. By providing a portal for readily accessing climate reconstructions at high temporal resolutions, PaleoView can help to better establish the consequences of past climate fluctuations on macro-ecological patterns of biological and genetic diversity.
