2026-09-10 Annual 1 km Agricultural Sunshine Zoning Dataset for Northeast China, 1951–2025 doi:10.57760/sciencedb.0121i en This dataset provides annual gridded agricultural sunshine-zone data for Northeast China from 1951 to 2025, comprising 75 annual layers. The layers are based on annual sunshine-related indicators in an agroclimatic resource product and assign each pixel an original zoning code from 1 to 4 according to the prescribed sunshine-zoning rules; 0 denotes NoData. Each layer is a single-band GeoTIFF at 1 km resolution in the WGS 84 Albers equal-area projection and uses uint8 encoding. Quality checks confirmed a complete 1951–2025 sequence and consistent raster dimensions, resolution, projection, geotransform, and NoData settings. All valid pixels contain integer zone codes from 1 to 4, and no valid pixels occur outside the Northeast China boundary, indicating that the rasters are already region-masked. The dataset supports analyses of agricultural sunshine resources, agroclimatic zoning, and crop-climate suitability in Northeast China. agricultural sunshine resources; sunshine zoning; Northeast China; agroclimatic resources Song Yilin jiang he ping Earth Resource Data Cloud Tengyue PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
