Description: Dynamic Atmospheric Correction based on: 

  • Mog2D-G High Resolution barotropic model developed by Legos/CNRS for high frequency (i.e less than 20 days) 
  • an IB correction developed by CLS, assuming a static response of the ocean to atmospheric forcing, and neglecting wind effects for low frequency (i.e more than 20 days)
