Abstract

This study compared the use of both the MODIS LAI (MOD15A2) product, which provides directly the 8-day LAI at 1km spatial resolution, and the MODIS 8-day surface reflectance product (MOD09A1) in retrieving and estimating the seasonal variation of LAI for irrigated rice in the Mekong delta, Vietnam. The Soil-Leaf-Canopy (SLC) radiative transfer model was employed to invert MOD09A1 reflectance spectra to get LAI estimates through the look-up table (LUT) approach. The result showed that the dynamic evolution of LAI of irrigated rice during one cropping season could be estimated fairly well by the SLC model (R 2 = 0.69, RMSE= 0.9). This result is a great improvement compared to the retrieved LAI from MOD15A2 (R 2 = 0.07, RMSE = 2.1).
