Estimating bamboo forest aboveground biomass using EnKF-assimilated MODIS LAI spatiotemporal data and machine learning algorithms

•A novel model is presented to estimate bamboo forest AGB from MODIS data.•EnKF algorithm highly improved the accuracy of MODIS LAI products.•AGB estimated using assimilated LAI was more accurate than using MODIS LAI products.•RF model has solved the collinearity and overfitting problem during AGB estimation.
