Annual 1 km Maize Planting Climate Suitability Index Dataset for Northeast China, 1951–2025
Listed in ScienceDB
This dataset provides annual gridded Maize Planting Climate Suitability Index data for Northeast China from 1951 to 2025, comprising 75 annual layers.
Description
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.
