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。
