S1-GRiTS: Gridded Monthly Descending-Pass Sentinel-1 Backscatter Composites and Mosaic for Mainland Ecuador, January 2026

This component contains national-scale gridded Sentinel-1 monthly composite products for mainland Ecuador in January 2026, generated from descending-pass observations by S1-GRiTS. The data were produced as part of the S1-GRiTS Data Cubes and were used to generate the national-scale mosaic demonstration in the associated manuscript. The released files include MGRS-tile-level GeoTIFF products (UTM Zone), a portable VRT mosaic (EPSG:4326), intermediate reprojected VRT files, visualization outputs, and machine-readable metadata files. The total of tiles is 40. The VRT files use relative source paths and are intended to remain valid after the component directory is downloaded and extracted, provided that the internal directory structure is preserved.本数据集组件包含2026年1月厄瓜多尔本土的全国尺度网格化哨兵1号（Sentinel-1）月度合成产品，该产品由S1-GRiTS（S1-GRiTS）的下行轨道观测数据生成。本数据集作为S1-GRiTS数据立方体项目的一部分制作完成，并用于生成相关研究手稿中的全国尺度镶嵌演示成果。 本次发布的文件包含军事格网参考系统（MGRS）瓦片级GeoTIFF产品（通用横轴墨卡托（UTM）分带）、可移植虚拟栅格数据集（VRT）镶嵌文件（EPSG:4326坐标系）、中间重投影VRT文件、可视化输出成果以及机器可读元数据文件。瓦片总数为40。VRT文件采用相对源路径，仅需保留内部目录结构，在下载并解压数据集组件目录后，该路径即可保持有效。
