Data Assimilation

A hierarchy of data assimilation techniques are evaluated as a function of computational resources and prediction accuracy:

  1. the Optimal Interpolation (OI)
  2. the Parameter Matrix Objective Analysis algorithm (PMOA)
  3. the Reduced Order Adaptive Filter (ROAF)
  4. the Reduced Order Information Filter (ROIF)
