Drylands present a challenging landscape for LAI and leaf chlorophyll (Chll) estimation.
LAI and Chll were retrieved with mean absolute errors of 12% and 16%, respectively.
Correction for adjacency effects reduced reflectances with up to 60%.
Considering adjacency effects and foliar dust reduced negative biases in LAI.
Integration of red-edge and empirical LAI helped constrain the inversion process.
