In 2021, Hurricane Ida left over 1 million people without power, tornadoes tore across the American Midwest, volcanoes forced people to evacuate their homes, wildfires covered the American West and unusual flooding wreaked havoc on Central Europe.

Instruments, like this flux tower, are used by scientists to verify the accuracy of the data available in OpenET, a powerful new web-based platform that puts Earth science data about water use by crops and other vegetation into the hands of farmers and water managers.

Terra Data Offline September 22 for Solid-State Recorder Reboot

On Wednesday, September 22, 2021, Terra’s Flight Operations Team will be rebooting Terra’s Solid-State Recorder (SSR). Terra’s nominal SSR operations will be offline for approximately 10 – 12 hours. The purpose of the Solid-State Recorder reboot is to restore function to the printed wire assemblies that are currently offline. During this period, many of the instruments will continue to collect data. However, data collected during this period will not be available (except for MODIS direct broadcast data) because the Solid-State Recorder, which stores the data until it can be downlinked, will not be online.

  • MISR – Normal Operations
  • MODIS – Normal Operations (Direct Broadcast will continue to be available)
  • MOPITT – Normal Operations
  • CERES – Safe Mode (no observations); CERES on other platforms ­– Aqua, Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 satellites will continue to operate as normal.
  • ASTER – Standby (no observations; nominal maneuver configuration)

Once the solid-state recorder reboot is completed, it is planned that all instruments and data collection will be restored to normal operations, including MODIS and MISR whose data were impacted by the most recent printed wire assembly anomalies in June, 2021.
