BioClimPolar_1980-2000是一个包含生物气候变量栅格地图图层的数据集，该数据集是专门为北极陆地和环极地地区（北纬45度以北的陆地表面）开发的，开发过程中考虑了动植物合理的生态需求。数据涵盖从公元1980年到公元2000年，分为三个离散的时间段，空间分辨率为10公里。该数据集与另一个数据集BioClimPolar_2300相互补充，一个聚焦过去，另一个着眼未来。生成该数据集所用的R脚本也一并提供（在Scripts.zip文件中）。", "ds_source": "

BioClimPolar1980-2000 is a dataset containing grid map layers of bioclimatic variables, specifically developed for the Arctic land and circumpolar regions (land surfaces north of latitude 45 degrees north), taking into account the reasonable ecological needs of animals and plants during the development process. The data covers the period from 1980 AD to 2000 AD, divided into three discrete time periods with a spatial resolution of 10 kilometers. This dataset complements another dataset BioClimPolar-2300, one focusing on the past and the other on the future. The R script used to generate this dataset is also provided (in the Scripts. zip file).", "ds_time_res": "", "ds_acq_place": "", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
