研究概要:The authors studied the effects of the degradation of NOAA/AVHRR sensor sensitivity and the geometry concerning to the zenith and azimuth angles of the sun and a sensor on the monitoring of land cover conditions using multi-temporal AVHRR data. The effect of sensor degradation on calibration of AVHRR visible and near-infrared channels was tested using the data taken in a desert area where the surface albedo was considered to be stable. The effect of solar-sensor geometry was tested using the three temporal data which were observed within a week and in different geometrical conditions and regression analysis was performed to study the effect of geometrical parameters on the correlation of surface albedos and NVI among the three different data.
