宏观生态学近年来蓬勃发展，部分原因是广泛的气候数据，如WorldClim和CliMond数据集提供的数据，这些数据已可用于研究。然而，重要的环境变量仍然缺失，包括空间数据集的UV-B辐射，越来越多地认识到生态processes.We的驱动程序开发了一套全球UV-B表面（glUV）适合匹配常见的空间尺度在macroecology。我们的数据集是基于美国宇航局臭氧监测仪器（Aura-OMI）的遥感记录。按照WorldClim和CliMond数据集的类似方法，我们将8年内获得的每日UV-B测量值处理为月平均UV-B数据和6个具有生态意义的UV-B变量，分辨率为15弧分。这些生物气候变量代表年平均UV-B、UV-B季节性、最高月平均UV-B、最低月平均UV-B、最高季度月平均UV-B总和和最低季度月平均UV-B总和。我们相关的数据集与选定的变量现有的生物气候表面的土地和Terra-MODIS海洋表面温度的海洋regions.UV-B表面测试已知的梯度和图案的关系表现出明显的季节性变化在全球范围内，而UV-B辐射的强度下降向高纬度和地形和气候的异质性修改。UV-B表面与全球平均温度和年平均辐射数据相关，但在整个地球仪中表现出可变的空间关联。除此之外，UV-B面与现有的生物气候面基本无关。我们的数据集为宏观生态分析提供了新的相关气候信息。由于UV-B是许多生物模式和过程的已知驱动因素，我们的数据集提供了在宏观生态学，地理学，全球变化研究等领域更好地了解这些动态的潜力。包含月平均紫外线-B数据和六个衍生紫外线-B表面的glUV数据集可在以下网址免费下载：。
Macroecology has prospered in recent years due in part to the wide array of climatic data, such as those provided by the WorldClim and CliMond data sets, which has become available for research. However, important environmental variables have still been missing, including spatial data sets on UV-B radiation, an increasingly recognized driver of ecological processes.We developed a set of global UV-B surfaces (glUV) suitable to match common spatial scales in macroecology. Our data set is based on remotely sensed records from NASA's Ozone Monitoring Instrument (Aura-OMI). Following a similar approach as for the WorldClim and CliMond data sets, we processed daily UV-B measurements acquired over a period of eight years into monthly mean UV-B data and six ecologically meaningful UV-B variables with a 15-arc minute resolution. These bioclimatic variables represent Annual Mean UV-B, UV-B Seasonality, Mean UV-B of Highest Month, Mean UV-B of Lowest Month, Sum of Monthly Mean UV-B during Highest Quarter and Sum of Monthly Mean UV-B during Lowest Quarter. We correlated our data sets with selected variables of existing bioclimatic surfaces for land and with Terra-MODIS Sea Surface Temperature for ocean regions to test for relations to known gradients and patterns.UV-B surfaces showed a distinct seasonal variance at a global scale, while the intensity of UV-B radiation decreased towards higher latitudes and was modified by topographic and climatic heterogeneity. UV-B surfaces were correlated with global mean temperature and annual mean radiation data, but exhibited variable spatial associations across the globe. UV-B surfaces were otherwise widely independent of existing bioclimatic surfaces.Our data set provides new climatological information relevant for macroecological analyses. As UV-B is a known driver of numerous biological patterns and processes, our data set offers the potential to generate a better understanding of these dynamics in macroecology, biogeography, global change research and beyond.
