摘要:
依据对MODIS数据36个波段波谱值的研究,选择对雪深信息最敏感的两个波段(第1波段,第3波段),采用“度日法”及积雪消融过程中的实测资料,建立了雪水当量统计模型.通过实测数据的进一步验证,该雪水当量监测模型的精度达到了0.86,可以为融雪径流计算、融雪洪水预测预警等工作提供重要的参数,为相关部门提供决策支持.
Abstract:
Two wave bands(1st wave band,third wave band) were chosen which are sensitive to snow depths based on 36-band spectrum of MODIS data.A snow equivalent statistical model was established by using the degree-day factor and a lot of measured data.The accuracy of snowmelt equivalent model reached 0.86,which would provide important parameters for snowmelt runoff computation,prediction,snowmelt flood forecasting and warning and also offer advice for the relevant departments.
