WebMoreover, triple collocation provides the relative linear calibration (scaling) of the three systems. Also, assuming known (normal) error distributions and after mutual linear calibration (rescaling) of the distributions with the errors, matching of the cumulative PDF leads to higher order calibration as well (known as CDF matching).

WebTriple collocation is a method to estimate the unknown error of three timeseries with the same underlying geophysical variable [Stoffelen1998]. It is based on the following error model: x = α x + β x Θ + ε x y = α y + β y Θ + ε y z = α z + β z Θ + ε z WebThe triple collocation method is implemented using ASAR GM, AMSR-E, and a model (either AWRA-L, GLDAS-NOAH, or ERA-Interim). First, the significance of the relationship between the three soil moisture datasets was tested that is a prerequisite for the triple collocation method. Second, the trends in Tc related to the choice of the third ...
