ChinaCropPhen1km: A high-resolution crop phenological dataset for three staple crops in China during 2000-2019 based on LAI products

This dataset provides 1km-grid crop phenological dataset for three main crops (i.e., rice, wheat, and maize) of China from 2000 to 2019.<br> *** The format of provided data is GeoTIFF, i.e., the georefercing information was embedded within the TIFF file. Each file was projected to the Asia North Albers Equal Area Conic projection, with a spatial resolution of 1km.<br>*** The pixel value is the Julian Day of the Year (DOY).<br> *** Filename convention: CHN_CropType_KeyPhenologicalStages_Year.tif *** CropType: includes Maize, Wheat, Rice(SR&amp;ER) and Rice(LR), where Rice(SR&amp;ER) represents single-rice and early-rice, Rice(LR) represents late-rice only.*** KeyPhenologicalStages: GR&amp;EM: Green up &amp; Emergence date for wheat; V3: V3 stage for maize; TR: Transplanting date for rice; HE: Heading date for all the crops; MA: Maturity date for all the crops. *** Year: Values from 2000 to 2019

本数据集提供了2000年至2019年中国三大主粮作物（水稻、小麦、玉米）的1km分辨率栅格作物物候数据集。
** 所提供的数据格式为地理标记图像文件格式（GeoTIFF），即地理参考信息内嵌于TIFF文件之中。所有文件均采用亚洲北阿尔伯斯等积圆锥投影（Asia North Albers Equal Area Conic），空间分辨率为1km。
** 像素值为年积日（Day of Year, DOY）。
** 文件名命名规范：CHN_CropType_KeyPhenologicalStages_Year.tif
- 作物类型（CropType）：包含玉米（Maize）、小麦（Wheat）、单季稻与早稻（Rice(SR&ER)）以及晚稻（Rice(LR)），其中Rice(SR&ER)代表单季稻与早稻，Rice(LR)仅指代晚稻。
- 关键物候期（KeyPhenologicalStages）：GR&EM为小麦的返青与出苗期；V3为玉米的V3生长期；TR为水稻的移栽期；HE为所有作物的抽穗期；MA为所有作物的成熟期。
- 年份（Year）：取值范围为2000年至2019年。
