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.

Question: Do L2 SNPP SST data have a flag to distinguish day/night SST?

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.

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.
