This function filters and gap-fills downloaded MODIS LAI data from the lpdaac AppEEARS download portal. There are several choices for processing this data:
The LAI data is processed using the phenofit R package https://github.com/kongdd/phenofit. A rough fit is done using a weighted Whittaker smoother and then curve fitting is done using an assymetric Gaussian function.
The LAI data is processed by using a Savitsky-Golay filter to remove noise and then missing data is interpolated with a spline.
The LAI data is processed by using a Savitsky-Golay filter to remove noise and then missing data is interpolated by fitting a double logistic curve using the greenbrown R package.
