Study of coastal water turbidity in Réunion Island
A lot depends on the definition of high resolution. If you can accept 250m-ish, and don't mind processing the data locally...MODIS Rrs_645nm might serve as a decent proxy for turbidity...300m-ish, MERIS with 709nm available...if you can live with 1km-ish, again MODIS and MERIS,...

There is nothing wrong with the products we produced, as the binner has no issues with them. The files you are passing to the binner have a problem.
You need to either figure out why they are suspect or remove the suspect files from your binning process.

Do L2 SNPP SST data have a flag to distinguish day/night SST?
For SST, the HISOLZEN flag bit of the l2_flags is set for solz > 90. So, if you are looking at SST products, you simply need to check the l2_flags to determine if the pixel is day or night. For ocean color products the HISOLZEN flag bit is set for solz > 70, so for those you would need t...

Well, that's the problem then. The L2 files are either corrupt or have too few pixels. Both cases will be a problem for the binner.

Loïc,If you use the apply_pal option in l3mapgen, the output TIFF image will be scaled to match the indexed color palette used in making the pretty picture.If you want to use the TIFF to represent geophysical values, set apply_pal=0 (the output will be grayscale, but the values will be floating poin...

MODIS/Aqua Reprocessing Version 2014.1
Bruce,
An estimate (although far from a good one) would be no earlier than mid-October. We are still polishing the cannon ball...uh...revising the calibration.
That is just about done, but there's a few other ducks to line up before we kick off the reprocessing.

Fedora26 should have no issues with running our code or connecting to our servers (I've not tested it, but it is the latest version and should "just work"). You mention you installed with sudo...you should not' do that. There is no reason to use sudo for installing the ...
