摘要: The study applies the improved cloud-free Moderate Resolution Imaging Spectral radiometer (MODIS) daily snow cover product (MODMYD_MC) to investigate variations from Hydrologic Year (HY) HY2000 HY2013 in Amur River Basin (ARB), Northeast Asia. fractions of forest were 38%, 63% and 47% 2009 China (the southern ARB), Russia northern ARB) ARB, respectively. Validation results show that MODMYD_MC has a agreement 88% against situ depth (SD) observations (SD≥4cm). is about 10% lower at forested stations than non-forested stations. Snow Cover Durations (SCD) are 20 days shorter ground (SD≥1cm) stations, while they just 8 Annual mean SCDs areas 21 those nearby farmland SanJiang Plain.
