NASA Daymet Project

This dataset provides annual climate summaries derived from Daymet Version 4 R1 daily data at a 1 km x 1 km spatial resolution for five Daymet variables: minimum and maximum temperature, precipitation, vapor pressure, and snow water equivalent. Annual averages are provided for minimum and maximum temperature, vapor pressure, and snow water equivalent, and annual totals are provided for the precipitation variable. Each data file is provided as a single year by variable and covers the same period of record as the Daymet V4 R1 daily data. The annual climatology files are derived from the larger d...本数据集基于Daymet Version 4 R1（Daymet V4 R1）的逐日数据，以1 km×1 km的空间分辨率，针对5项Daymet变量生成年度气候汇总数据，涵盖最低气温、最高气温、降水量、水汽压及雪水当量。其中最低气温、最高气温、水汽压与雪水当量提供年度平均值，降水量变量则提供年度累计总量。每份数据文件按变量与单一年份进行划分，其记录时段与Daymet V4 R1逐日数据完全一致。本年度气候学文件源自规模更大的d……
