what is the problem about this picture?

hello everyone:
I do a aerosol forcing experiment by cam3.0,but the variable of total optical depth thickness is abnomal,I do not know what cause this problem?if someone give me some suggestion about it, I will appreciate very much,Thanks in advance!

The image you attached is very poor, could you try again. Is the problem the strong blue badning at what looks like the tropopause region everywhere?

thanks for help!I am sorry to my poor picture.I feel puzzled about this picture because the distribution of total aerosol optical depth in visible,this is a field of (lon,lat),but not about (lev),so i think the aerosol optical depth is abnomal... and i do not know why this problem happen and how to solve this problem?
In addition,this picture is the distribution of total aerosol optical depth in visible,the value is from 0 to 0.6,the intensive isoline is of small value,the smallest is 0,just near to the blue line.
