Hector simulation

• We found simulation largely depending on
• Model initialization scheme
• Lateral boundary conditions
• Physical processes represented in the model

Summary

• Two modes of simulation
• OF doesnt work too well in generality
• DA gives good agreement for a lot of cases, but
  the statistics show too low cloud fraction.
• Aerosol effects are present for the 6th February
  case.
• Need more simulations of different cases to see
  how robust this is.
