• There will be a data and imagery outage in GIBS and Worldview starting 10 October 2022 and will last 10+ days for layers created from the MODIS, MISR, CERES, and ASTER sensors aboard the Terra satellite.
• MOPITT NRT imagery will be unavailable for a longer period of time, from 3 October to 28 October 2022.
• Worldview will set the Aqua/MODIS Corrected Reflectance layer as the default layer for that period. Note that Aqua has a later overpass time (1:30PM mean local time) than Terra (1:30PM MLT10:30AM mean local time), so there will be a longer delay for Corrected Reflectance imagery to appear in Worldview.
• We will include notifications in Worldview to remind users of the outage.

The Terra satellite is scheduled to exit the “Morning Constellation” of the Earth Observing System (EOS) satellite program in October 2022. The initial Terra Constellation Exit Maneuver (CEM) is scheduled for 12 October 2022 around 7:30AM EDT and 19 October 2022. All Science and Near Real-Time (NRT) data will not be acquired starting 10 October 2022 until 19 October 2022. Post-CEM, more time will be needed to bring all Terra instruments back up to their nominal states and necessary calibrations and Lookup Table (LUT) updates will occur as needed. Users should exercise caution while using Terra data between 19 - 21 26 October as all instruments will still be recovering, after the outage. This will impact all sensors aboard Terra including MODIS, MISR, MOPITT, ASTER, and CERES.
