Hawkeye processing with MUMM

[tsm00]

Hi,

Does Seadas 8.2 have the capability of processing Hawkeye level 1 images to level 2 with the MUMM scheme?

Thanks!

Yes, the code works with Hawkeye...hasn't been evaluated with it, but it doesn't blow up, so that's a good sign

Hi Sean,

It blew up on one image we tried it on (Mac version). We have a few more scenes we'll try it on, and I'll respond back to this thread later.

Thanks!

[OB.DAACx - SeanBailey]

The error message indicates what went wrong
As a variant of the Gordon and Wang approach, the MUMM algorithm requires two bands to do the atmospheric correction.
The Hawkeye default configuration uses a CZCS-like approach and so specifies aer_wave_long and aer_wave_short as the same band (670nm). All you should need to do is set aer_wave_long=867 and aer_wave_short=752.
Keep in mind that the gains were defined for the CZCS-like correction, so no guarantees that they are appropriate for the MUMM approach.

Thank you so much, it is now working!
