About

pyDINEOF is a Python version of DINEOF.

DINEOF is an EOF-based method to fill in missing data from geophysical fields, such as clouds in sea surface temperature, and is available as compiled Fortran code.

For more information on how DINEOF works, please refer to Alvera-Azcarate et al. (2005) and Beckers and Rixen (2003). The multivariate application of DINEOF is explained in Alvera-Azcarate et al. (2007), and in Beckers et al. (2006) the error calculation using an optimal interpolation approach is explained. For more information about the Lanczos solver, see Toumazou and Cretaux (2001).
