The purpose of this paper is the introduction of effective parameters into the presumption of the amount of diffusing cedar pollen using remote sensing data obtained by artificial satellites. Due to the purpose, some methods to estimate the seasonal variations of vegetation areas are applied. One of the methods is the analysis of Normalized Differential Vegetation Index (NDVI) calculated from the optical and near- infrared image data, and the other is the analysis of back-scattering coefficients obtained by Synthetic Aperture Radar (SAR) image data. For SAR data, we propose the index based on entropy computed from the co-occurrence matrix formed by two seasonal images. The results investigated the relationship these parameters and the amount of diffusing cedar pollen are reported.
