Second try with full seaice adjoint 7 days integration from 2009/1/1 Difference from 1 st try:

Second try with full seaice adjoint 7 days integration from 2009/1/1 Difference from 1 st try: no OCCA climatology (to isolate sieaice alone) Note: 1) seaice dynamics ON in forward but OFF in adjoint 2) uniform uncertainty to calculate cost of misfit of model/obs seaice area

  1. Second try with full seaice adjoint 7 days integration from 2009/1/1 Difference from 1st try: no OCCA climatology (to isolate sieaice alone) Note: 1) seaice dynamics ON in forward but OFF in adjoint 2) uniform uncertainty to calculate cost of misfit of model/obs seaice area 3) atmos controls are {'atemp','aqh','uwind','vwind','precip','swdown'} adjusted every 2-day Looking at cost and associated sensitivity and comapring with 1st try 1) cost: SMR_area: 2.8457e+05 same, no OCCA 2) adj sensitivity of atmos fields look unstable at some regions

  2. Cost of model/obs seaice area (7 days accumulated)

  3. Surface ADJtheta (7days prior )

  4. adxx_atemp (7days prior )

  5. adxx_aqh (7days prior )

  6. adxx_uwind (7days prior )

  7. adxx_vwind (7days prior )

  8. adxx_precip (7days prior )

  9. adxx_swdown (7days prior )

  10. Time series of extreme value ADJtheta (k=1) Time series of extreme value ADJtheta (k=1) from 1-month adjoint run (w/ OCCA and ARGO)

  11. Surface ADJtheta (31days prior )

  12. adxx_atemp (31days prior )
