虽然现在已经有100多年的历史了，但最初由Wlaundi Koppen制定并由他的合作者和继任者修改的气候分类仍然被广泛使用。它被广泛用于教学学校和本科生的气候课程。它也仍然是一系列学科的研究人员经常使用的基础上气候区域化的变量和评估全球气候模型的输出。在这里，我们已经产生了一个新的全球气候地图使用Koppen-Geiger系统的基础上，长期的每月降水量和温度站的时间序列的大型全球数据集。Koppen-Geiger系统中使用的气候变量是在每个站计算的，并使用二维（经度和纬度）薄板样条在0.1度x0.1度上进行插值。每个大陆的V网格。我们讨论了一些问题，在处理的网站，没有被唯一地划分为一个气候类型的Koppen-Geiger系统和评估的结果在大陆的基础上。全球最常见的气候类型是BWh（14.2%，热沙漠），其次是Aw（11.5%，热带萨凡纳）。更新的世界Koppen-Geiger气候图可在补充材料部分免费获得电子版（http：www.hydrol-earth-syst-sci.net/ 11/1633/2007/hess-11-1633-2007-supplement.zip）。
Although now over 100 years old, the classification of climate originally formulated by Wladimir Koppen and modified by his collaborators and successors, is still in widespread use. It is widely used in teaching school and undergraduate courses on climate. It is also still in regular use by researchers across a range of disciplines as a basis for climatic regionalisation of variables and for assessing the output of global climate models. Here we have produced a new global map of climate using the Koppen-Geiger system based on a large global data set of long-term monthly precipitation and temperature station time series. Climatic variables used in the Koppen-Geiger system were calculated at each station and interpolated between stations using a two-dimensional (latitude and longitude) thin-plate spline with tension onto a 0.1 degrees x 0.1 degrees. V grid for each continent. We discuss some problems in dealing with sites that are not uniquely classified into one climate type by the Koppen-Geiger system and assess the outcomes on a continent by continent basis. Globally the most common climate type by land area is BWh (14.2%, Hot desert) followed by Aw (11.5%, Tropical savannah).
