Hello, gnwiii, long time no see, have you been busy recently?
I would like to ask you a question, can you use seadas tool to adjust MODIS L1B data from 500 meters to 30 meters resolution?

Thank gnwiii for you answer

The first url link is available, I'll go over the report and try to find the answer,

However, this second website cannot open "a broken link to "modis_hires".

Thank gnwiii very much for your answer.

I has see the answer of the l2gen, But How can the low resolution image of 1km be improved to the high resolution of 500m? Setting the resolution to 500m is a parameter. What method does L2gen use to improve the resolution? Resampling or something.

Thank gnwiii very much for your answer?In the near shore and shallow water area, The depth of water and bottom reflectances don't know. This is a big question. I having to solve the problem with other answer.When I am using L2gen atmospheric correction, why do I need to input MOD021KM L1B data t...

Thank gnwiii very much for your answerWhile I was working on this problem, I came across another one.Does L2gen's TSM_SWIM algorithm work close to shore?Are there any parameters that can be adjusted in the TSM_SWIM algorithm in L2gen to better match the inversion of suspended sediment concentrat...

Thank gnwiii very much for your answer

In the nowdays,I have solves the question.Thank you very mcuh.

Now, I have a Seadas gpt?Graph Processing Toolkit?question.
How can I use it to reprojection in the nc format remote image, the image is the L2gen result.

Thank you for your answerI have adjusted the parameters to make the reflectivity of the estuary appear, but I don't know if the values obtained by this method are correct, I am look for  other data to verify. And I am looking for MOD23 - Suspended solids, on oceancolor couldn't find it,...

Thank gnwiii very much for your answer, I understand what you mean. At present, this problem has not been solved, but by adjusting parameters, some pixel values in the estuary area are not empty values. I have a question, L2 image by atmospheric correction of L2gen obtain the reflectivity value of w...

When I process L1b image of the estuary use the L2gen, I find the result image L2 have the NaN data in the estuary, And I look for the L2gen algorithm for the solve the problem.So I find the shallow water <30m of areas are not treated. the estuary and coast be contained to the shallow water.I would ...

the l2gen have the parameter water(ifile), and the L2 rrs data have the flat COASTZ parameter(shallow water<30m),
so the estuary and nearshore to become the NAN.
But I need the estuary and nearshore of L2 rrs data to make the study.
Can you give me some advices to solve the problem?
