2000-2022年中国高时空分辨率SIF数据集
收藏资源简介:
2000-2022年中国高时空分辨率SIF数据集(简称HCSIF),基于加权Stacking方法,结合MODIS反射率、温度、ERA-5气象数据、DEM数据生成。空间分辨率为500m,时间分辨率为8天,数据范围自2000年至2022年,缩放因子为0.0001。HCSIF的生成算法在测试集上获得了较高精度(R²=0.87,RMSE=0.057mW/m²/nm/sr),HCSIF数据集与OCO-2 SIF数据、GOME-2 SIF数据、塔基实测SIF数据以及GPP通量观测数据对比评估过程中也取得了良好的验证效果。数据集提供GeoTIFF和NetCDF两种存储格式,可按需下载。
2000–2022 China High Spatiotemporal Resolution Solar-Induced Chlorophyll Fluorescence Dataset (abbreviated as HCSIF) was generated based on the weighted Stacking method, combining MODIS reflectance, air temperature, ERA-5 meteorological data and DEM data. It has a spatial resolution of 500 m, a temporal resolution of 8 days, covers the period from 2000 to 2022, with a scaling factor of 0.0001. The HCSIF generation algorithm achieved high accuracy on the test set (R²=0.87, RMSE=0.057 mW/m²/nm/sr). The HCSIF dataset also yielded excellent validation performance during comparative evaluations against OCO-2 SIF data, GOME-2 SIF data, tower-based in-situ SIF data and GPP flux observation data. The dataset is provided in two storage formats, GeoTIFF and NetCDF, and can be downloaded as required.
