Data file search omits MODIS Aqua level-3 monthly binned SST for first 4 months of 2015

Using the Data File Search page (with "Generate checksum text file" checked) the .L3b_MO_SST.nc files for the first 4 months of 2015 were not included in the generated list although the files are available in the level-3 browser.

A few files had an incorrect status flag set, hiding them from the search utility....try again.

Thanks. I had already downloaded the files, but I'm happy to report that the shasums for files downloaded from the browser all check OK.

Using "File Search" on Friday for the period 2015-01-01--2015-04-30, pattern "A2015*.L3b_MO_SST.nc", level3-binned MODIS Aqua products, I was sure I saw sha1sums for all 4 missing files, but today, I noticed that April is missing from my saved sha1sums file. Running "File Search" again today omits April, 2015.

Using your query parameters returns April 2015 for me...

Edit: I was gently reminded that we're in the middle of reprocessing the daytime SST data,....
The April monthly was regenerated between when you queried and when I queried...

Thanks for the explanation. I see the checksums have changed from last week. Does this reprocessing get a new improved number or is it included in R2014.0.1?

It is bringing the older data up to R2014.0.1. I'm waiting on the SST PI to provide a blurb about the update before making the "official" announcement, but since the cat is out of the bag ... a flaw in the flagging criteria was identified and corrected. This went into the forward stream in March of 2016, but since then the impact was seen as having a broader impact necessitating the reprocessing.

Thanks. I'll be interested to see the PI's blurb when it comes.
