It is well known that microwave emission from soil is very well correlated to its moisture content. One experimental area near Changchun was selected for the research of retrieval of soil moisture from C-band microwave radiometer. Measurements were carried out on bare smooth soils, bare soils with ridge, dry grass covered soils and standing straw covered soils with different view angles. Soil moisture...
In this study, we present spectral measurements of soybean LAI and their estimation from reflectance spectra data in Songnen Plain. Soybean canopy reflectance and its derivative were subsequently used in a linear regression analysis against LAI on one by one spectral reflectance. It was found that determination coefficient for LAI was high in blue, red and near infrared spectral region, and it was...
