本数据集包含覆盖新疆及其周边缓冲区的地表温度每日合成栅格序列，空间分辨率为 1000 m，时间范围为 2000—2025年。数据包含 MOD11A1 12个子数据集：LST_Day_1km、LST_Night_1km、QC_Day、QC_Night、Day_view_time、Night_view_time、Day_view_angl、Night_view_angl、Emis_31、Emis_32、Clear_day_cov、Clear_night_cov。原始图像为 MODIS Sinusoidal 投影，经处理后统一为WGS84 经纬度（EPSG:4326）。\n数据的目录组织：包含origin、origintif、mos三个数据子目录，其中origin目录下是原始hdf格式的分幅文件，origintif目录下是由hdf数据文件逐数据集转换而成的tif格式数据文件，每个分幅hdf生成12个单波段tif文件；mos目录下是各分幅拼接好的覆盖新疆区域的地表温度产品，可以作为最终产品直接使用。origintif下由各波段转出的tif格式文件与orgin目录下的原始hdf文件是一一对应，可以根据实际使用环境选择不同的数据格式作为处理输入。

The original images were captured using the MODIS Sinusoidal projection, and have been converted into WGS84 latitude and longitude coordinates (EPSG:4326) after processing.\r\n\r\nThe data is organized in three sub-directories: origin, origintif, and mos. The origin directory contains the original hdf format files. The origintif directory contains tif format files that are derived from the hdf data files, with each file containing data for a single band. Each hdf file is converted into 12 tif files representing individual bands. The mos directory contains the combined surface temperature products for the region covering Xinjiang, which can be used directly as the final product. The tif files in the origintif directory correspond one-to-one with the original hdf files in the origin directory, allowing users to choose different data formats based on their specific needs.", "ds_source": "Using MODIS/Terra MOD11A1 as the data source", "ds_process_way": "After formatting conversion, projection transformation, band extraction, and image splicing processing,", "ds_quality": "This product inherits the inverted accuracy of the original L2-level products, which is ±1.5K.
