Difficulties with accessing NOAA CPC 4-km Merged Global IR data resulted in the loss of IR data in IMERG Early Run for 12 November 12:00-21:30 UTC and 14 November 10:00-15 November 10:30 UTC, and in IMERG Late Run for 12 November 12:00-20:30 UTC and 14 November 10:00-15 November 09:30 UTC.  Subsequently, the IR data were retrieved for use in the Final Run.
