Manasi River Basin is located in the north submontane of Tianshan Mountains,Xinjiang Province,China.As a typical basin of the arid zone in the northwest of China,there are many glaciers developed in the high altitude areas and snow covered in the basin from winter to the following spring.Thus,it has great significance of the snow and glacier melt runoff to the industry,agriculture,ecology,and environment of the basin.Over the last five years,we im-plemented scientific investigation,snow observation,and satellite-ground simultaneous observation in the basin.The high-resolution optical remote sensing data,i.e.GF-1 PMS(Panchromatic and Multi-Spectral)/WFV(Wide Field of View)and HJ-1 CCD(Charge-Coupled Device)/IRS (Infrared Scanner),and synthetic aperture radar data with C band,i.e.RADARSAT-2 and ENVISAT ASAR were used in the study.The comprehensive radiation correction method was explored considering the rugged terrain of the mountainous areas.The snow recognition models were built to obtain snow cover extent,snow surface type,and snow situation of dry or wet.The snow retrieval models were built to obtain snow grain size,snow depth,and snow water equivalent.The snow change characteristics and snow cover recession processes were analyzed to realize the parameter optimization,simulation,and forecast of the snowmelt runoff model.The study fruits will provide scientific supports for the water resource utilization and man-agement of the basin.
