泾惠渠灌区气象要素和潜在蒸散发量敏感性分析数据集

在1961-2011年陕西省泾惠渠灌区内泾阳、高陵、临潼和富平4个气象站逐日气象资料基础上，作者采用Penman-Monteith公式计算潜在蒸散发量（ET₀），采用无量纲的相对敏感系数分析ET₀对4个主要气象要素（相对湿度、太阳辐射、风速和气温）的敏感性，得到泾惠渠灌区气象要素和潜在蒸散发量的敏感性分析数据集。数据集包括：（1）泾惠渠灌区范围和泾阳、高陵、临潼和富平4个气象站点位置地理信息系统数据；（2）泾惠渠灌区气象要素和潜在蒸散发量的敏感性分析数据，包括：每个气象站气象要素（气温、相对湿度、风速和太阳辐射）多年（1961-2011）平均逐日数据（表1-表4）；1961-2011年各台站历年潜在蒸散发量（ET₀）数据（表5）；每个气象台站气象要素敏感系数多年平均逐日数据（表6-表9）；气象要素敏感系数多年平均逐日数据（表10）；气象要素敏感系数多年平均逐月数据（表11）。该数据集存储为.shp和.xlsx格式，数据压缩为204KB。该数据集的分析研究成果发表在《自然资源学报》2015年30卷第1期。

Based on the daily meteorological data from four meteorological stations (Jingyang, Gaoling, Lintong and Fuping) in the Jinghui Canal Irrigation District of Shaanxi Province during 1961–2011, the authors calculated the potential evapotranspiration (ET₀) using the Penman-Monteith equation, and analyzed the sensitivity of ET₀ to four main meteorological factors (relative humidity, solar radiation, wind speed and air temperature) using dimensionless relative sensitivity coefficients, thereby establishing a sensitivity analysis dataset of meteorological factors and potential evapotranspiration for the Jinghui Canal Irrigation District. This dataset includes: 1. Geographic Information System (GIS) data of the scope of the Jinghui Canal Irrigation District and the locations of the four aforementioned meteorological stations; 2. Sensitivity analysis data of meteorological factors and potential evapotranspiration in the Jinghui Canal Irrigation District, which consists of: - Multi-year (1961–2011) averaged daily data of meteorological factors (air temperature, relative humidity, wind speed and solar radiation) for each meteorological station (Tables 1–4); - Annual potential evapotranspiration (ET₀) data for each station during 1961–2011 (Table 5); - Multi-year averaged daily sensitivity coefficients of meteorological factors for each meteorological station (Tables 6–9); - Multi-year averaged daily sensitivity coefficients of meteorological factors (Table 10); - Multi-year averaged monthly sensitivity coefficients of meteorological factors (Table 11). This dataset is stored in .shp and .xlsx formats, with a compressed size of 204 KB. The research findings based on this dataset were published in *Journal of Natural Resources*, Volume 30, Issue 1, 2015.
