Have you verified that your polar wander file exits and is up to date (i.e. have you recently run update_luts)?
It should be under $OCVARROOT/common/polar_wander.ascii

Sean

[lihao1991]

Thank you for your reply. I really haven't updated this file. Where can I download it?

[OB.DAACx - SeanBailey]

If you run the update_luts script, the polar wander file (as well as other required LUTs) will be retrieved and put in the correct ___location:

Code: Select all

$ update_luts viirsn
