IMERG Real Time IR Outage

For the period 03Z August 21 to 16Z August 22, the IMERG real time system experienced an outage of CPC 4-km IR data.  Despite the outage, IMERG EARLY and LATE products continued to be produced but users should be aware that the quality of these products during this period may be suspect and should be used judiciously.  Furthermore, the products for the first few hours after the outage are less than optimal due to IMERG restart but should be acceptable for most users.
