Proper Orthogonal Decomposition of Solar Photospheric Motions
Physical Review Letters, 2005 The spatio-temporal dynamics of the solar photosphere is studied by performing a Proper Orthogonal Decomposition (POD) of line of sight velocity fields computed from high resolution data coming from the MDI/SOHO instrument. Using this technique, we are able to identify and characterize the different dynamical regimes acting in the system. Low frequency

A Group Condensation Method Based on Proper Orthogonal Decomposition
Yuanzineng kexue jishu, 2023 The group condensation is a key process of the two-step method and is the guarantee of efficiency of the two-step method. However, the group condensation of the two-step method also reduces the energy resolution and leads to the calculation errors.
