In LAIr: Converting NDVI to LAI of Field, Proximal and Satellite Data

#' Dataset of empirical functions to convert NDVI to LAI in crops, forests and mixed vegetation.
#' @description Dataset of empirical functions to convert NDVI to LAI, compiled by [Bajocco et al. 2022](https://www.mdpi.com/2072-4292/14/15/3554).
#' It contains some arguments used by the [NDVI2LAI()] function to subset the conversion equations.
