Phenology pattern data indicating recovery trajectories of ponderosa pine forests after high-severity fires

This tabular, machine-readable CSV file contains annual phenometrics at locations in ponderosa pine ecosystems across Arizona and New Mexico that experienced stand-clearing, high-severity fire. The locations represent areas of vegetative recovery towards pre-fire (coniferous/pine) vegetation communities or towards novel grassland, shrubland, or deciduous replacements. Each sampled area is associated with the point location (latitude/longitude) as well as multiple calendar year phenometrics derived from the time-series of normalized difference vegetation index (NDVI) values in the phenology software package Timesat v3.2.

本数据集为可机器读取的表格型CSV文件，涵盖美国亚利桑那州与新墨西哥州境内经历过全林焚毁型高烈度火灾的美国黄松（Ponderosa Pine）生态系统各点位的年度物候参数。这些点位对应区域正处于火灾后的植被恢复阶段：部分区域恢复至火灾前的针叶林/松林植被群落，另有部分区域演替为全新的草原、灌丛或落叶植被群落。每个采样区域均关联有对应的点位坐标（纬度/经度），同时包含多组基于物候学软件Timesat v3.2中归一化差分植被指数（Normalized Difference Vegetation Index，NDVI）时间序列提取得到的年度物候参数。
