Re: Error Processing VIIRs - Ancillary_NASA()

This directory is under the uncompressed folder of polymer. You may try it again.

Good luck.

Re: Strips in Polymer VIIRS Rw image

Dear François, Thank you for your reply. I got it. In addition, I checked the corresponding VIIRS L2 data which included stripes too. But after I reprojected the VIIRS L2 data, the strips disappeared. So the reprojection method that I used was able to fix the strips in the L2 data. But I wonder why ...

Strips in Polymer VIIRS Rw image

Dear François, After I processed VIIRS L1C data by Polymer, the Rw images included many stripes. Take Rw551 for example. Then I reprojected Rw551 image using seadas, however, the reprojected image included strips too. Do you know what caused the strips and how to deal with them? Thank you. Kind rega...

Re: Error converting VIIRS L1A to L1C data

Dear François,

Thank you for your reply. Yes, you're right. Now I can convert VIIRS L1A to L1C.

Kind regards,

Error converting VIIRS L1A to L1C data

Hello,

I downloaded VIIRS L1A and GEO files from the NASA Ocean Color website. Then I tried to convert the L1A file to L1C file using l2gen and make_L1C.py separately, but both got error.

Could anyone tell me how to fix it?

Thank you.
Mengmeng.

Re: Error Processing VIIRs - Ancillary_NASA()

Hello,

I met a similar problem before and the solution was to create those two directories using this command (on linux): "mkdir -p ANCILLARY/METEO/".

Good luck.

Re: Modify Polymer scripts for CASI-1500 data

Hi François, I'm sorry for your confusion. My goal is to apply Polymer to my airborne data (CASI-1500). For now, the only difference that I wanna make to Polymer is the initial atmospheric correction, for which I used the 6SV ratiative transfer model which is able to simulate atmospheric parameters ...

Re: Modify Polymer scripts for CASI-1500 data

Hello François, To modify the Polymer scripts, maybe I can start with the codes after intial atmospheric correction. For example, for a given pixel radiance value from my CASI-1500 data, I can do initial correction with the parameters, such as total ozone transmittance, Rayleigh reflectance, direct ...
