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
