On 07.12.21 (2021.193) the Terra MODIS instrument experienced a data loss during a daytime orbit over Australia. Due to weather, the relay satellites TDE and TDS were unavailable starting with the 01:16:00z TDS contact. Blind acquisitions were scheduled in order to attempt to recover data. After the blind acquisitions were performed, there was still missing MISR and MODIS data. Currently, geolocation and L1B reflectance and thermal bands are impacted for granules 00:50 through 01:00 inclusive. At this time it is unclear if this data loss is recoverable, this note will be updated accordingly as more information becomes available. Below are the data segment start and stop times for the lost MODIS APID 64 data.
