榆中站2021-2023年大气环境要素日尺度数据集

本数据集为甘肃省榆中山地生态系统野外科学观测研究站典型草原观测点所收集2021年1月1日至2023年12月31日的日尺度大气环境要素数据集，包括（1）地面气象要素：空气温度、相对湿度、大气压、风速、风向、地表温度、降水量、日照时数；（2）辐射数据：入射短波辐射、出射短波辐射、入射长波辐射、出射长波辐射、光量子通量密度、净辐射；（3）通量数据：净生态系统碳交换、总初级生产力、生态系统呼吸、水通量、蒸散发、显热通量、潜热通量和土壤热通量等指标。

This is a daily-scale atmospheric environmental dataset collected at the typical grassland observation site of the Yuzhong Mountain Ecosystem Field Scientific Observation and Research Station in Gansu Province, covering the period from January 1, 2021 to December 31, 2023. The dataset includes the following three categories of indicators: 1. Surface meteorological parameters: air temperature, relative humidity, atmospheric pressure, wind speed, wind direction, surface temperature, precipitation, and sunshine duration; 2. Radiation measurements: incident shortwave radiation, outgoing shortwave radiation, incident longwave radiation, outgoing longwave radiation, photosynthetic photon flux density (PPFD), and net radiation; 3. Flux metrics: net ecosystem carbon exchange (NEE), gross primary productivity (GPP), ecosystem respiration, water flux, evapotranspiration, sensible heat flux, latent heat flux, soil heat flux, and other related indicators.
