Note
On DOY 2020.279 (10.05.20) MODIS Terra experienced a PWA failure that affected two more PWA-41 (supersets 80 and 81), bringing down the total number of MODIS SS to 28. The current PWA failure event happened around 15:21:12z. FOT was able to move the two corrupt supersets to the bad superset list at the contact on 2020.280/03:28:00 - 03:46:00z. Science recording was disabled at 03:32:56 to handle the moving of the supersets and re-enabled at 03:41:56z.
Terra MODIS shows partial to full science data loss on 2020.279 for NRT and C6/C61 forward production over the following time ranges (15:05, 16:45, 18:30), where the data could not be played back because of recording on the faulty PWA-41. The image below for DOY 2020.279, shows these gaps across the globe for NRT.

UPDATE 07.06.21
************************************************On June 29, 2021 (DOY 180), Terra experienced another PWA failure (PWA-47), affecting the supersets of 92/93, bringing down the total number of MODIS SS to 26. The failed MODIS supersets from PWA 47 were successfully removed and operations were completed during the contact (181/01:55:09 - 02:05:44z) at 01:58z. Terra MODIS shows partial to full science data loss on 2021.180, and 181 for NRT and C6/C61 forward production. The overall impacted range for MODIS is: 180/13:06:23 - 181/00:07:41. However, MODAPS is currently working to fill in the data to the best possible extent, and more information will be posted to the forward processing note when recovery efforts have been completed. Images below for DOY 2021.280 and 2021.181 show these gaps across the globe for NRT.
