2019-2021中国典型生态系统通量观测站配套辐射数据集

本数据集包括4部分：（1）半小时尺度辐射数据，包括2019至2021年60个典型生态系统（森林、草地、荒漠、农田、湿地）通量观测站点的总辐射、净辐射、光合有效辐射等观测数据，经数据质量控制、校正和插补的半小时均值；（2）日尺度辐射数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）日尺度辐射观测数据，是在校正和插补后的半小时尺度数据基础上，计算得到的各观测指标的日均值、最大值和最小值数据；（3）月尺度辐射数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）月尺度辐射数据，是在日尺度数据基础上统计计算得到的各观测指标的月均值、最大值和最小值数据；（4）年尺度辐射数据，包括2019至2021年60典型生态系统（森林、草地、荒漠、农田、湿地）年尺度辐射数据，是在日尺度数据基础上统计计算得到的各观测指标的年均值、最大值和最小值数据。This dataset consists of four components: (1) Half-hourly scale radiation data: This includes observed metrics such as global radiation, net radiation, and photosynthetically active radiation from 60 flux observation stations spanning five typical ecosystem types (forest, grassland, desert, cropland, and wetland) for the period 2019–2021. These are half-hourly mean values that have undergone data quality control, correction, and gap-filling. (2) Daily scale radiation data: This consists of daily-scale radiation observation data from the same 60 flux stations across the five aforementioned ecosystem types during 2019–2021. These datasets are derived by computing daily mean, maximum, and minimum values of each observed metric based on the corrected and gap-filled half-hourly scale data. (3) Monthly scale radiation data: This includes monthly-scale radiation data from the 60 flux stations across the five typical ecosystem types during 2019–2021. These values are calculated as monthly mean, maximum, and minimum values of each observed metric based on the daily scale radiation datasets. (4) Annual scale radiation data: This covers annual-scale radiation data from the 60 flux stations across the five typical ecosystem types during 2019–2021. These are calculated as annual mean, maximum, and minimum values of each observed metric based on the daily scale radiation datasets.
