1Spatial and Temporal Variability of Snow Depth Derived from Passive Microwave Remote Sensing Data in Kazakhstan显示文摘Snow cover plays an important role in the hydrological cycle and water management in Kazakhstan.However, traditional observations do not meet current needs. In this study, a snow depth retrieval equation was developed based on passive microwave remote sensing data. The average snow depth in winter(ASDW),snow cover duration(SCD), monthly maximum snow depth(MMSD), and annual average snow depth(AASD) were derived for each year to monitor the spatial and temporal snow distribution. The SCD exhibited significant spatial variations from 30 to 250 days. The longest SCD was found in the mountainous area in eastern Kazakhstan, reaching values between 200 and 250 days in 2005. The AASD increased from the south to the north and maintained latitudinal zonality. The MMSD in most areas ranged from 20 to30 cm. The ASDW values ranged from 15 to 20 cm in the eastern region and were characterized by spatial regularity of latitudinal zonality. The ASDW in the mountainous area often exceeded 20 cm.MASHTAYEVA Shamshagul DAI Liyun CHE Tao SAGINTAYEV Zhanay SADVAKASOVA Saltanat KUSSAINOVA Marzhan ALIMBAYEVA Danara AKYNBEKKYZY Meerzhan 2016Journal of Meteorological Research2016,30,6:1
