Infrared Sea Surface Temperature Data Reconstruction Using Dineof Method

Due to the influence of clouds and other factors on radiometers operating in the optical and infrared bands, satellite data of sea surface temperature (SST) usually has large areas missing. This will have a severe impact on its application. In this study, Data Interpolation Empirical Orthogonal Function (DINEOF) method was applied to reconstruct the missing values of SST in a region in Southeast Asia. The DINEOF was used to the 2019 Moderate Resolution Imaging Spectroradiometer (MODIS) Aqua L3 SST data, and its accuracy was assessed by comparing Argo data, satellite data, and reconstructed data. And Argo data was used to correct the reconstructed data. The corrected Std and RMSE were 0.3992 and 0.3951, respectively.
