| Abstract | Remote sensing satellite images have the potential to monitor agricultural crops throughout the growing season and are, therefore, an important tool to provide relevant information for agricultural crop forecasting models. Leaf area index (LAI) is one of the most important variables to monitor the development of agricultural crops and can be estimated from remote sensing data. This work aims to compare three LAI computing methods using MODIS surface reflectance data. In 2006, 2117 samples were selected over planted sugarcane areas in Sao Paulo state. In 2007, these same areas were selected again this time over first ratoon sugarcane areas. After that, NDVI (Normalized Difference Vegetation Index) was calculated from MODIS/Terra surface reflectance 8-day composite (MOD09Q1) and linked to LAI via three different mathematical functions. For the two years of sugarcane growing season, NDVI ranged from 0 to 0.99. Larger NDVI values were observed throughout the rainy season. The harvest event varied for the sugarcane sampled fields in both years; however, the start point of the growing season was almost the same for both years. Different LAI values were obtained for each LAI computing method; however, these differences were merely mathematical. Methods 1 and 3 had good performance to estimate LAI whereas method 2 overestimates LAI values. Prior to the use of MODIS/Terra 8-day composite it is essential to detect and eliminate or minimize images noise. | |||
