摘要
采用EOS-Terra/MODIS数据对内蒙古的沙尘暴进行监测研究。通过分析沙尘暴的波谱特征和MODIS传感器通道的特点,采取基于双通道阈值的叠加分析法对沙尘暴进行提取监测。结果表明基于双通道阈值的叠加分析法有利于对沙尘暴信息的准确提取,为利用MODIS数据进行沙尘暴监测提供了有效手段。
In this paper, EOS-Terra/MODIS data is used in the study of monitoring duststorm in Inner Mongolia. By analyzing the spectral response characteristics of duststorm and the bands from MODIS sensor, the method superposition analysis based on the boundary limit values of two bands is put forward. The results showes that the superposition method based on the thresholds of two bands is an ideal method to accurately derive the information about duststorm and provides an effective means to use MODIS data.
