CRU TS v4.09 Monthly Potential Evapotranspiration Data (1901–2024)

This file contains monthly gridded estimates of potential evapotranspiration (PET) from the Climatic Research Unit Time-Series (CRU TS) Version 4.09 dataset, covering global land areas from 1901 to 2024. The data are provided in NetCDF format and compressed using gzip. Each 0.5° grid cell records PET in millimeters per month, calculated using the Penman-Monteith method or related algorithms. PET is a critical variable for hydrological modeling, drought monitoring, agricultural planning, and climate impact studies. This dataset enables long-term analysis of atmospheric water demand and trends in terrestrial climate dynamics.本文件包含来自气候研究单元时间序列（Climatic Research Unit Time-Series, CRU TS）4.09版数据集的逐月网格化潜在蒸散量（potential evapotranspiration, PET）估算结果，覆盖1901年至2024年的全球陆地区域。该数据以NetCDF格式存储，并通过gzip进行压缩。每个0.5°网格单元的潜在蒸散量以毫米/月为单位进行记录，其计算采用彭曼-蒙特斯法（Penman-Monteith method）或相关算法。潜在蒸散量是水文建模、干旱监测、农业规划以及气候影响研究中的关键变量。本数据集可支持针对大气需水状况以及陆地气候动态变化趋势的长期分析。
