四川省公里格网蒸散数据(2000-2014)

本数据集包含了2000-2014年15年的四川省公里格网蒸散数据，以空间分辨率为1km，时间分辨率为月，数据类型为栅格数据，tif格式，数据更新频度为12个月。该原始数据来源于NASA数据发布中心MODIS的地表蒸散产品16A2分幅数据，原数据格式为HDF格式，将原始HDF格式转化为tif格式，经投影转换为albers投影，并拼接裁剪生成2000-2014年四川省地表蒸散产品数据。模型算法主要参考借鉴基于InVEST模型的三江源区生态系统水源供给服务时空变化《应用生态学报》。主要应用于地理学、生态学等相关领域研究，以期为相关研究人员提供生态系统公里格网蒸散数据，顺利开展科研活动。

This dataset provides 15-year (2000–2014) 1-kilometer grid evapotranspiration data for Sichuan Province, featuring a spatial resolution of 1 km, monthly temporal resolution, stored in raster TIFF format, with an annual update frequency. The original raw data was obtained from the MODIS 16A2 tiled surface evapotranspiration products hosted by the NASA Data Distribution Center. The initial data was in HDF format, which was converted to TIFF format, reprojected to the Albers equal-area projection, then mosaicked and clipped to generate the finalized surface evapotranspiration product dataset for Sichuan Province spanning 2000–2014. The modeling algorithm for this dataset primarily draws reference from the study *Spatiotemporal Changes of Ecosystem Water Supply Services in the Three-River Source Region Based on the InVEST Model* published in the *Chinese Journal of Applied Ecology*. This dataset is primarily intended for research in relevant disciplines including geography and ecology, aiming to supply researchers with grid-scale ecosystem evapotranspiration data to facilitate their scientific research endeavors.
