江苏省淮安市金湖县参考作物腾发量分析数据

采集浙江托普云农智慧农业气象站设备上的温度、湿度、风速等数据，分析计算参考作物腾发量ET0，为农田水分盈亏分析提供数据支撑，指导农田科学灌溉和排水，从而提高作物的产量和质量。1、数据来源：通过浙江托普云农智慧农业气象站设备TP-WMS-1L、TP-WMS-1P和TP-WMS-1等，实时监测空气温度、湿度和风速,以一定采集周期上传即时数据。 2、数据处理 对采集到的数据进行去重、合并，按照区域分类、统计处理，计算出每日太阳净辐射量（W/m²）、平均温度（℃）、平均风速（m/s）、平均饱和蒸汽压（Pa）、环境湿度（%rh）、大气压值斜率、空气湿度等参数，基于这些参数，利用以下公式计算参考作物腾发量ET0： ET0=0.408*每日太阳净辐射量*大气压值斜率/（大气压值斜率+（空气湿度常数*（1+0.34*平均风速）））+900*平均风速/（平均温度+273.15）*（平均饱和蒸汽压-环境湿度）*空气湿度常数/（大气压值斜率+（空气湿度常数*(1+0.34*平均风速）））。 3、数据应用：通过长期ET0数据跟踪与分析，实现对该区域农田的蒸发蒸腾监测，为灌溉和排水提供数据支撑，从而提高作物的产量和质量。

This dataset collects data including air temperature, humidity, wind speed and other relevant parameters from Zhejiang Topcloud Agri-Tech's smart agricultural weather station devices, analyzes and calculates the reference crop evapotranspiration (ET0), provides data support for farmland water surplus and deficit analysis, and guides scientific irrigation and drainage of farmlands to improve crop yield and quality.

1. Data Source: Data are collected via Zhejiang Topcloud Agri-Tech's smart agricultural weather station models TP-WMS-1L, TP-WMS-1P and TP-WMS-1, which conduct real-time monitoring of air temperature, humidity and wind speed, and upload real-time data at a fixed collection interval.

2. Data Processing: The collected data are deduplicated, merged, classified by region and statistically processed. The following parameters are calculated: daily net solar radiation (W/m²), mean air temperature (℃), mean wind speed (m/s), mean saturated vapor pressure (Pa), ambient humidity (%rh), slope of atmospheric pressure value, and air humidity constant. Based on these parameters, the reference crop evapotranspiration ET0 is calculated using the following formula:
ET0 = 0.408 imes ext{Daily net solar radiation} imes ext{Slope of atmospheric pressure value} / ( ext{Slope of atmospheric pressure value} + ext{Air humidity constant} imes (1 + 0.34 imes ext{Mean wind speed})) + 900 imes ext{Mean wind speed} / ( ext{Mean air temperature} + 273.15) imes ( ext{Mean saturated vapor pressure} - ext{Ambient humidity}) imes ext{Air humidity constant} / ( ext{Slope of atmospheric pressure value} + ext{Air humidity constant} imes (1 + 0.34 imes ext{Mean wind speed}))

3. Data Application: Through long-term tracking and analysis of ET0 data, evapotranspiration monitoring of farmlands in this region can be realized, providing data support for irrigation and drainage, thereby improving crop yield and quality.
