A dataset of meteorological observations at Jilin Da'an National Field Observation and Research Station of Agroecosystem from 2017 to 2021
Meteorological data are essential for accurate weather warnings and are also of great significance to agricultural production.Jilin Da'an National Field Observation and Research Station of Agroecosystem(Da'an Station)is located in the west of Songnen Plain,characterized by a mid-temperate continental monsoon climate.This region boasts abundant sunlight year-round,with simultaneous rainfall and heat,which is conducive to crop growth.However,the widespread presence of saline-sodic soil in the region poses great challenges to agricultural development and ecological security.To address these challenges,we compiled the meteorological observation data from 2017 to 2021 into a dataset on hourly,daily and monthly scales through data processing and quality control of the original observations from the meteorological observation field at Da'an Station.The dataset covers temperature,air pressure,relative humidity,wind speed,rainfall,soil temperature(0-20 cm),total radiation,reflected radiation,photosynthetically active radiation,soil heat flux and sunshine hours.It is aimed to provide basic data reference for studying the saline-sodic soil in Northeast China,developing characteristic ecological agriculture in saline-sodic soil,ensuring food security and ecological security,so as to further provide data support for the treatment of saline-sodic desertification and comprehensive utilization of saline-sodic land in China.
