WebThe DINEOF method utilizes the spatio-temporal coherency of the data to estimate the missing values, and has been successfully applied to various ocean color data, including Chl-a, the diffuse attenuation coefficient (Kd), satellite-derived sea surface temperature (SST) and normalized water-leaving radiance spectra (e.g., [19,20,24,25,26]). WebJul 4, 2024 · This function is based on the DINEOF (Data Interpolating Empirical Orthogonal Functions) procedure described by Beckers and Rixon (2003).

WebThe statistical rival to frequentism is the Bayesian approach to statistical inference. If you’re used to working with priors and posteriors, and use the phrase “It is what you believe it is,” then you’re probably a Bayesian. Bayesian statistics were developed by Thomas Bayes, an 18th-century English statistician, philosopher, and minister. WebTo complete the picture, the gap-filling application uses a mathematical technique based on the data interpolating empirical orthogonal function (DINEOF) (Alvera-Azcarate et al., 2005; Beckers and Rixen, 2003). This technique exploits the coherency over location and time of the data from the two satellites to infer a value at the missing location."
