西藏澎波灌区气象、土壤温度、土壤水分、作物腾发及渗漏数据集（2022-2023）

本数据集包含的气象、土壤水分、土壤温度、作物腾发和渗漏数据均在西藏自治区拉萨市澎波灌区监测获得。数据集包含了西藏澎波灌区2022年6月1日~2023年10月31日，以小时为序列的气象数据，由全自动气象站（编号：NHQXZ601）监测获取得到，其中包括降雨、气温、太阳辐射、相对湿度数据等。利用东方智感墒情仪（智墒）监测小黑麦地、燕麦地土壤水分及土壤温度变化，数据采集间隔以小时记，实测时间为2022.06.01~2023.10.31。土壤温度和土壤水分数据较为详实，利用统计学方法可以反映出土壤水分和温度在时、天、月、季、年不同时间尺度的变化规律，也可较好的满足农田水热运移模型的率定和验证需求。数据集还包括了作物腾发数据和渗漏数据，利用LYS80（圆柱形容器，不锈钢材质，直径60cm，高度60cm）蒸渗仪实测获得，此数据有助于解析西藏高寒地区农作物在整个生育期耗水量及不同生长阶段的耗水量及渗漏量，对明晰不同农田系统的水量平衡发挥重要作用。该数据集提供的西藏澎波灌区气象，土壤水分、土壤温度、蒸腾和渗漏数据，有助于揭示农田尺度、灌区尺度的水转化过程和充分认识西藏高寒区SPAC系统的水热传输过程，作物生长状态。

This dataset contains meteorological, soil moisture, soil temperature, crop evapotranspiration and percolation data collected via on-site monitoring in the Pengbo Irrigation Area, Lhasa, Tibet Autonomous Region.

The hourly meteorological data covers the period from June 1, 2022 to October 31, 2023 in the Pengbo Irrigation Area, Tibet, and was monitored by an automatic meteorological station with the ID NHQXZ601, including rainfall, air temperature, solar radiation, relative humidity and other related variables.

Soil moisture and soil temperature in triticale and oat plots were monitored using the Dongfang Zhigan ZhiShang soil moisture sensor, with hourly sampling interval, during the same period from June 1, 2022 to October 31, 2023. The collected soil temperature and moisture data are comprehensive, which can be used to reveal the variation patterns of soil moisture and temperature across different temporal scales (hourly, daily, monthly, seasonal and annual) via statistical analysis, and well meet the requirements for calibration and validation of farmland water-heat transport models.

The dataset also includes crop evapotranspiration and percolation data measured by a LYS80 lysimeter, which is a cylindrical stainless steel container with a diameter of 60 cm and height of 60 cm. These data help analyze the water consumption and percolation of crops during their entire growth period and different growth stages in the alpine region of Tibet, and play an important role in clarifying the water balance of various farmland systems.

The meteorological, soil moisture, soil temperature, evapotranspiration and percolation data from the Pengbo Irrigation Area, Tibet provided by this dataset contribute to revealing water transformation processes at farmland and irrigation area scales, and fully understanding the water-heat transport processes and crop growth status in the SPAC (Soil-Plant-Atmosphere Continuum) system of the Tibet alpine region.
