利用GRACE重力卫星反演2003～2013年新疆天山地区陆地水储量时空变化
|
摘要
利用2003-1~2013-12的GRACE月重力场数据来计算新疆天山地区陆地水储量的变化,采用去相关滤波和300km高斯滤波相结合的方法来滤除GRACE数据中的噪声,同时采用尺度因子的方法来减小GRACE后处理误差的影响,并利用Paulson模型结果来扣除由冰川均衡调整(GIA)对水储量反演结果的影响,把得到的最终结果与同期GLDAS、CPC水文模型进行了验证分析。结果表明,GRACE反演结果与两个水文模型的模拟结果变化趋势基本一致,在2003~2013年间,研究区域的水储量整体上呈现下降趋势,速率为-0.54±0.27mm/a左右,但期间水储量变化波动较大,在2008年10月份左右,该区域水储量较同期呈现明显减小,这与该时段的干旱事件相一致。
The terrestrial water storage changes(TWSC)in Tianshan Mountains,Xinjiang of China was inferred using the GRACE monthly gravity data from 2003 to 2013.The noise existed in GRACE data was filtered by the combination of de-correlated technique and 300 km Gaussian filter,and the GRACE post-process errors was reduced by the scaling factor,and the effect caused by GIA was cut down by the model provided by Paulson.The final GRACE result is consistent with the GLDAS and CPC hydrological models.The preliminary result indicates that the water storage present a decreasing rate which is about-0.54±0.27mm/a in the Tianshan region,However,the TWSC fluctuates largely,specially,it shows a significant decrease in October 2008,which coincides with the drought conditions in the same period.The spatial distribution of TWSC shows a downward trend in the most parts of Tianshan region,with the maximum rate of-5.6±1.6mm/aappearing in the middle of the Tianshan Mountains.
