CRU TS v4.09 Monthly Diurnal Temperature Range Data (1901–2024)

This file contains monthly gridded data for diurnal temperature range (DTR) from the Climatic Research Unit Time-Series (CRU TS) Version 4.09 dataset, spanning 1901 to 2024. Stored in NetCDF format and compressed using gzip, it provides global land-surface values at 0.5° spatial resolution. DTR measures the difference between daily maximum and minimum temperatures and is crucial for studying climate variability, energy balance, agriculture, and health impacts. The dataset supports long-term climate research, modeling efforts, and integration with other CRU TS variables such as precipitation, cloud cover, and mean temperatures.

本文件包含来自气候研究单位时间序列（Climatic Research Unit Time-Series, CRU TS）4.09版本数据集的气温日较差（diurnal temperature range, DTR）月度格点数据，时间跨度为1901年至2024年。该数据集采用NetCDF格式存储并经gzip压缩，提供空间分辨率为0.5°的全球陆面数据。气温日较差指每日最高气温与最低气温的差值，其在气候变率研究、能量平衡分析、农业研究及健康影响评估等领域具有重要意义。本数据集可支撑长期气候研究、气候建模工作，并可与CRU TS的其他变量（如降水、云量与平均气温）实现整合。
