In order to acquire more accurate crop yield information, the global optimization algorithm SCE-UA was used to integrate leaf area index derived from remote sensing with crop growth model EPIC to simulate regional summer maize yield and field management information in Huanghuaihai Plain in China. The results showed that the mean relative error of estimated summer maize yield was 4.37% and RMSE was...
Canopy interception of rainfall plays an important role in hydrologic cycling and water balance of ecosystems in arid and semi-arid regions. At present, most research focuses on the characteristics of interception at the stand or plot scale. Studies of canopy interception at the river basin or landscape scale based on RS and GIS are lacking because the factors influencing canopy interception such...
In this paper an overview of the main microwave characteristics observed on three forest areas selected in different areas worldwide is given. Microwave parameters were analyzed for a yearly cycle (2007-2008), paying particular attention to the seasonal variations forest leaf biomass, expressed as leaf area index (LAI), and climatic conditions. Some microwave indexes of polarization and frequencies...
