江苏省启东市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 such as air temperature, humidity and wind speed from smart agricultural weather stations manufactured by Zhejiang Top Cloud-agri Technology, to analyze and calculate the reference crop evapotranspiration (ET0), provide data support for farmland water surplus and deficit analysis, and guide scientific irrigation and drainage in farmlands, thereby improving crop yield and quality.
1. Data Source: The stations including models TP-WMS-1L, TP-WMS-1P and TP-WMS-1 perform real-time monitoring of air temperature, humidity and wind speed, and upload real-time data at a fixed collection cycle.
2. Data Processing: The collected data are deduplicated, merged, classified by region and statistically processed to derive parameters including daily solar net radiation (W/m²), average temperature (℃), average wind speed (m/s), average saturated vapor pressure (Pa), ambient humidity (%rh), atmospheric pressure slope and air humidity. Based on these parameters, the reference crop evapotranspiration (ET0) is calculated using the following formula:
ET0 = 0.408 * daily solar net radiation * atmospheric pressure slope / (atmospheric pressure slope + air humidity constant * (1 + 0.34 * average wind speed)) + 900 * average wind speed / (average temperature + 273.15) * (average saturated vapor pressure - ambient humidity) * air humidity constant / (atmospheric pressure slope + air humidity constant * (1 + 0.34 * average wind speed))
3. Data Application: Through long-term tracking and analysis of ET0 data, evapotranspiration monitoring of farmlands in the target region is implemented, providing data support for irrigation and drainage, thereby improving crop yield and quality.
