Land protection model dataset

Data used to model satellite-derived Normalized Difference Vegetation Index (NDVI) in response to precipitation on areas of the Brazilian semi-arid Caatinga biome under different protection levels. Variables: cell_id - Numeric ID of the pixel included in the analysis ndvi - Montlhy Normalized Difference Vegetation Index (NDVI) score of the pixel prec - Monhtly precipitation value of the pixel long - Longitude of the pixel centroid lat - Latitude of the pixel centroid protection_type - Catogrical variable indicating the level of land protection in the pixel, including no protection, sustainable use or full protection status.本数据集用于构建巴西半干旱卡廷加（Caatinga）生物群系不同保护等级区域内，响应降水的卫星遥感归一化差异植被指数（Normalized Difference Vegetation Index, NDVI）模型所需数据。 变量说明： cell_id：本次分析纳入的像元数值ID ndvi：对应像元的月度归一化差异植被指数得分 prec：对应像元的月度降水量值 long：对应像元质心的经度 lat：对应像元质心的纬度 protection_type：分类变量，用于表征该像元的土地保护等级，涵盖无保护、可持续利用及全面保护三类状态。
