DESCRIPTION:Even though modern experimental techniques produce flow fields
  that rival numerically generated data in terms of spatial and temporal re
 solution\, the methods that analyze and quantify these experimental data l
 ag far behind the possibilities available for numerical simulations. The r
 eason for this discrepancy is the necessity of a model equation to extract
  relevant flow information using standard decomposition techniques. A new 
 data-based method will be introduced and demonstrated that\, using only sn
 apshots\, is capable of identifying dynamically relevant temporal and spat
 ial scales in form of spectral information and modal structures. Applicati
 ons of this method to experimental and numerical data will range from simp
 le flames to wake\nflows\, from acoustically active flows to a jet in cros
 sflow.
