中国山东禹城站2020年叶面积指数(LAI)数据
收藏资源简介:
2020年5-11月利用山东禹城站叶面积指数传感器网络系统SBLX-034进行观测。筛选位于有效观测时间的数据,并依据站点间的时空相关性利用时序神经网络NARX建模,剔除模型预测误差异常的数据,并利用LSTM神经网络对处理后的数据规律进行检验。最后对每天的数据进行平均处理得到长时间序列的LAI实测相对真值。
Observations were conducted using the leaf area index sensor network system SBLX-034 at the Yucheng Station in Shandong Province from May to November 2020. Valid data within the valid observation periods were screened out first. Then, modeling was carried out using the time-series neural network NARX based on the spatiotemporal correlations between stations, and data with abnormal model prediction errors were eliminated. Subsequently, the LSTM neural network was utilized to verify the patterns of the processed data. Finally, daily averaging was performed on the dataset to obtain the long-time-series measured relative true values of LAI.
