The pentad files:

were recreated on 27Sep2017 to correct a bias in the western tropical Atlantic.

The bias was caused by an analysis overcorrection in response to a
sudden and significant increase in the number of ocean profile observations
near Hurricane Irma.  The bias was corrected by rerunning the daily analyses
for the affected dates with additional data thinning in the pre-processing step.
