2026-09-18 Annual 1 km Maize Planting Climate Suitability Index Dataset for Northeast China, 1951–2025 doi:10.57760/sciencedb.012lw en This dataset provides annual gridded Maize Planting Climate Suitability Index data for Northeast China from 1951 to 2025, comprising 75 annual layers. Based on 1 km agroclimatic resource grids, it integrates growing-season temperature, precipitation, sunshine, and thermal conditions. The suitability of individual climate factors was standardized and combined to derive a 0–100 index, with higher values indicating more suitable climatic conditions for maize cultivation. Each layer is a single-band GeoTIFF at 1 km resolution in the WGS 84 Albers equal-area projection, retaining the original float32 index values and using −9999 as NoData. Quality checks confirmed a complete 1951–2025 sequence, consistent raster dimensions, grids, projection, and NoData settings across all 75 layers, an overall valid-value range of 1.2500–100, and no valid pixels outside the Northeast China boundary. The dataset supports agroclimatic resource assessment, maize planting-layout analysis, and studies of climate-change impacts in Northeast China. maize planting; climate suitability index; Northeast China; agroclimatic resources Song Yilin jiang he ping Earth Resource Data Cloud Wang Chunxu Tengyue PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
