北纬18°以北中国陆地生态系统逐月净初级生产力1公里栅格数据集（1985-2015）

作者运用1985-2015年中国陆地逐月气象数据、全国土壤质地数据和基于MODIS和AVHRR遥感影像的土地覆被和植被指数数据产品，输入Carnegie-Ames-Stanford Approach(CASA)模型，研发了北纬18&deg以北中国陆地生态系统31年逐月净初级生产力1公里栅格数据集（1985-2015）。数据研发范围为18&degN-53.5&degN，65&degE-138&degE，该区间中国以外陆地部分和海域部分设值为零，其余部分数据均为NPP数值。数据存储为.tif格式，分辨率为1km x 1km。数据集由1488个数据文件组成，数据量为28.2 GB（压缩为6个数据文件，压缩后数据量为2.07 GB）。基于该数据集的相关研究成果发表在《Remote Sensing》2017年第9期。

The authors utilized monthly meteorological data over terrestrial China from 1985 to 2015, national soil texture dataset, and land cover and vegetation index products derived from MODIS and AVHRR remote sensing imagery as input drivers for the Carnegie-Ames-Stanford Approach (CASA) model, and developed a 31-year (1985–2015) monthly 1-kilometer grid dataset of net primary productivity (NPP) for terrestrial ecosystems in China north of 18°N. The spatial extent of this dataset is 18°N–53.5°N and 65°E–138°E. All terrestrial and marine regions outside of China within this boundary are assigned a value of 0, while valid NPP values are stored for the remaining areas. All data are stored in .tif format with a spatial resolution of 1 km × 1 km. This dataset comprises 1488 individual data files with an uncompressed total size of 28.2 GB; it is compressed into 6 files with a total compressed size of 2.07 GB. Relevant research based on this dataset was published in *Remote Sensing*, Issue 9, 2017.
