Starting at 08:38 UTC PPS stopped getting data from the GPM Mission Operations Center. Data was resumed at 17:21 UTC. However, new GPS data was sent before older GPS data. The science data was sent out of order with the GPS data. This meant that about 125 mins of 1B and 1C GMI data had no geolocation and perhaps more after this had questionable geolocation. The same issues obviously also affected the radar and combined NRT which are just missing for the period between 8:30 UTC and 17:30 UTC.
All of these issues impacted the early version of the IMERG data. The late product will also be affected when its latency reaches the affected period without combined data.
You should use GPM data from the affected period with caution.
