动力降尺度方面,国内外研究大多借助WaterGAP水文模型(WaterGAP hydrology model,WGHM)和陆面模型(land surface model,LSM),利用集合卡尔曼滤波(ensemble kalman smoother,EnKS)等数据同化算法,结合GRACE/GRACE-FO监测信息与模型模拟结果,生成时...

A self-proclaimed family person, she’ll undoubtedly tell you that she considers one of her biggest accomplishments include becoming the wife of actor Kevin Cheng and mother of their son, Rafael (with baby number two on the way). aaaaabbnn 晚照清舟 9 We recently caught up with Chan —...
proposes the surface response research framework for the evolution of underground space , and reveals the formation mechanism on the surface subsidence response model , thereby establishing an emerging risks prevention and control early warning mechanism for underground space security and realizing scientific...
We provide a new analysis of glacial isostatic adjustment (GIA) with the goal of assembling the model uncertainty statistics required for rigorously extracting trends in surface mass from the Gravity Recovery and Climate Experiment (GRACE) mission. Such statistics are essential for deciphering sea level...
(Loomis et al., 2019) C2,0 Stokes coefficients calculated using a time-variable gravity model derived from GRACE in the forward modeling of the SLR solution (Loomis et al., 2019), as opposed to the fixed background model used by Cheng and Ries (2017), which has been the standard ...
地球重力场随时间的变化来源于地球系统的质量重新分布, 在几年或更短的时间尺度上, 地球表面质量迁移主要产生于大气压力、海底压力和陆地水储量的变化。卫星重力计划的科学任务就是探测地球重力场并进而反演地球系统质量的重新分布等信息, 于2 0 0 2年3月成功发射两颗卫星的美德合作计划GRACE (Gravity Recovery And...
Under the christological model, sin is defined as that which is opposed to what God has done for humanity in Jesus Christ, whereas grace is defined as the gift of what God has done for us in Jesus Christ.Cheng, Patrick ShuHsiang
Mylk Labs founder and CEO Grace Cheng. So, why oatmeal? "I discovered oatmeal when I was 18, and I kid you not, I've been eating it every day since. It's been almost a decade. If I don't start my day with oatmeal, I don't feel right. I've been modeling for over a decad...
