This data set provides continuous global average daily sun induced chlorophyll fluorescence (SIF) data in southwest China from September 2014 to July 2020 with a spatial resolution of 0.05 degrees (about 5 kilometers from the equator) and a 16 day temporal resolution. This product comes from the SIF observation of OCO-2, which is generated by training the artificial neural network (ANN) for the original SIF observation of OCO-2 and the seven band surface reflectivity corrected by MODIS BRDF along the OCO-2 track. Then, according to MODIS reflectance and land coverage, the trained ANN model is applied to predict the average daily SIF (mW/m2/nm/sr) of the blank area of OCO-2. The framework was stratified according to biological communities and 16 day time steps.
