DESCRIPTION
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 - PowerPoint PPT PresentationTRANSCRIPT

Second try with full seaice adjoint7 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 adjoint2) uniform uncertainty to calculate cost of misfit of model/obs seaice area3) atmos controls are {'atemp','aqh','uwind','vwind','precip','swdown'}
adjusted every 2-day
Looking at cost and associated sensitivityand comapring with 1st try1) cost: SMR_area: 2.8457e+05 same, no OCCA2) adj sensitivity of atmos fields look unstable at some regions
