triple collocation方法 Triple collocation (TC) 方法是一种用于比较并评估时空数据集之间相互一致性的方法。TC方法可以确定在多个数据集中测量与变化的一致性,并可以消除由于公共分辨率限制和不同传感器等因素导致的误差。该方法已经被广泛应用于水文学,气象学,地理信息系统和其他科学领域中,可以提高各种数据集之间的一致...
方法2 % In approach 2 we can estimate the triple collocation errors, the scaling parameter β and the signal to noise ratio directly from the covariances of the dataset. For a general overview and how approaches 1 and 2 are related please see [Gruber_2015]. %% Estimation of the error vari...
可以用三套独立的数据进行相互验证,称为三源匹配,这就是:Triple Collocation。 以下就学习到的内容对于Triple Collocation进行简单说明,如有不足之处,还请见谅。 通过现场测量、卫星海洋遥感或者数值模式模拟,可以得到对于某一研究变量真实值的三套估计值 X、Y、Z,每一套估计值均为时间或空间采样集合。假设估计值和...

Triple Collocation(TC)方法是一种有效的误差估计方法,以西江流域广东省肇庆—佛山段为研究区域,使用TC方法的理论公式对研究区域内的SMAP L3、SMOS L3和AMSR2 L3土壤湿度数据进行计算,求得3种土壤湿度数据的误差估计值,并将利用地面观测站点数据作为真值...
Triple collocation is a method that is now widely used to characterize systematic biases and random errors in in-situ measurements, satellite observations and model fields. It attempts to segregate the measurement uncertainties, geophysical, spatial and temporal representation and sampling differences in ...
Categorical Triple Collocation (CTC) is a technique for estimating the relative performance rankings of three measurement systems (e.g., satellite, in-situ and model-based products) based on their measurements of a binary/categorical variable with unknown true value (e.g., landscape freeze/thaw ...
Triple collocation TC (Gruber et al., 2016; Stoffelen, 1998) is a statistical method to estimate the random error variance of three independent datasets. A commonly used error model in TC approach is expressed as:i=αi+βiΘ+εiwherei∈[X,Y,Z] are three collocated independent datasets....
