DINEOF reconstruction

Daily Mediterranean Sea SST reconstruction using DINEOF


Geophysical data sets, such as those obtained from satellites, often contain gaps (missing values) due to the presence of clouds, rain, or simply due to incomplete track spatial coverage. There is a rising need, however, for complete data sets at the global, regional and local scale: several analysis methods, input for hydrodynamic models and data visualization are examples of applications where complete data sets are preferred or even necessary.

DINEOF is an EOF-based method to fill in missing data from geophysical fields, such as clouds in sea surface temperature. Based on Empirical Orthogonal Functions (EOFs), DINEOF uses an iterative procedure to calculate the values at the missing locations. The source code is open and available for everybody (see links below).
